Exercise: Control the strength of a colour

For this exercise, I've chosen a yellow framed pictured in a yellow wall as subject. I've used a manual exposure metering instead of the camera's metering to set the average exposure values. I've set an ISO 800 and 1/60 as shutter speed and the metering has given an aperture of f/8. So using such values I've varied the aperture, shooting two underexposed and two overexposed pictures according to my exposure metering. So here are the results:

    
ISO 800
1/60   f/5,6
20 mm

ISO 800
1/60   f/6,7
20 mm

ISO 800
1/60   f/8
20 mm
ISO 800
1/60   f/9,5
20 mm

                         
ISO 800
1/60   f/11
20 mm

So the conclusions I've made after the exercise are that saturation  increases (the yellow is stronger) when I've underexposed the image but brightness decreases. On the other side, when I've overexposed the image looks brighter but also less saturated, so the yellow is washed out.

Tutor report comments

I agree with every word. Tutor says to revisit picture about vertical&horizontal lines to notice how vetical lines convert in diagonal. He's right but I didn't have any other picture to reflect horizontal&vertical lines. Anyway as soon as I get it, I'm going to replace it.

I found the Assigment a little bit hard to complete and I think this is because I chose flowers and plants as subject. They never appealed me too much and I wanted to try a new "world" for me because I think trying new things is the best way to learn. So I agree that I was not able to capture the essence of the subject as well as anyone who has some experience on it.

Tutor advises me not to be so literal with the subject and I think it's one of my biggest handicap because I tend to be like that. I tend to be very explicit and descriptive myself and I think this is reflected in my photography as tutor guessed. So I'll try to give my pictures a new point of view.

Overall Comments


You have chosen from the module flowers and plants, as a subject, to explore the design elements within a photograph. This is fine but you need to be aware of comments made by Michael Freeman in his opening to this section. These concern focussing of attention on to the graphic elements of the photograph, with this subject, and many others, it can become quite challenging to obtain simple and elegant compositions that exploit the elements you are looking for.

Images like the ones you have submitted would benefit from research and referencing to other photographers work. In this case the flower images of Robert Maplethorpe would have been an appropriate inspiration for you as would the black and white images of tulips by John Blakemore. I will comment more about this at the end.

Since your feedback on assignment one the OCA have introduced a slightly amended feedback form, this incorporates a statement to indicate your assessment potential, should you be hoping to submit work at the end of The Art of Photography for formal assessment. Ideally you should have this after assignment one but I include it on this feedback form.

Feedback on assignment


1. Single Point. Good use of shallow depth of field to isolate the subject. Michael Freeman talks about how colour can be used as a tool in composition and in this case it is colour that is helping to isolate the single point. As a graphic shape the white centre of the flower is where the eye comes to rest and as such this becomes the 'point' in the image. What does become problematic is the fairly complex background and detail of the leaves which detract from the 'purity' of the single point. Although in this case the strong colour helps to direct the eye towards the 'point' detail such as the yellow leaf behind the flower also starts to act as a point and becomes distracting.

2. Two Points. I like your comments concerning use of portrait format which is appropriate for this subject. This image successfully illustrates how two points occurring in nature can be photographed and the graphic qualities of these shapes can be exploited within a photograph. This is part of 'seeing' as a photographer and you have seen this potential and captured it, well done. Your choice of aperture to isolate the subject from the background is appropriate but as you mention in your comments this is not entirely successful, the foreground framing works well and helps to lead the eye into the composition. I find the strong diagonal branch that is behind the flowers slightly distracting, this raises questions such as: 'Should the photographer rearrange nature or capture it as seen' and also starts to ask questions about truth in photography, you will need you to research into this later on in the course. If you could not remove it before taking the photography simply placing a leaf on to the branch, to appear natural and to break the line on the right would help to reduce its strength and distraction.
As the D90 has a sensor which is not full frame means that you need quite large apertures to start to get really shallow depth of field. So shooting at f4.8 is starting to achieve this but f2.8 or even larger would produce a greater result. With the larger (full frame) sensors the light is spread out over a greater surface area which enable you to achieve shallow DoF with much more control.

3. Several Points in a deliberate shape. Your comments about the difficulty of this exercise are well founded. It is far harder to purposefully arrange a subject to appear as 'natural' than to actually photograph nature - or is it? (see comments above!). I actually really like your composition, your choice of colours and the confined colour palette you are working with and shapes work well together,  you have produced a natural looking and sensitively arranged photograph. Your reflective comments illustrate how your thoughts and the process you have gone through to achieve this result have led you to a successful outcome, well done. I like the soft and uncomplicated light in this image as it creates no harsh and potentially distracting shadows. What works very well is your decision to allow some elements with the image to extend out of the frame, this allows the eye to roam around the image and contains it within the frame and is an effective part of your composition.

4. A combination of vertical and horizontal lines. A simple image that has partially captured these elements, although the main horizontal in this case is a diagonal and it is the diagonal that gives this image a dynamic quality.
The stone background is effective as it has an ambiguity and is interesting but is not distracting, I do find the foreground leaves problematic (as your own comments). Several of the leaves have lines which are also diagonal. So not entirely successful Eider and I suggest re-visiting this exercise.

5. Diagonals.  This is a graphic image with a strong diagonal. The use of a diagonal will often introduce a dynamic quality to an image. It is the dynamic that will lead the eye through the composition and generate a sense of movement and excitement. Diagonals occur naturally and photographers often tilt the camera to create a diagonal where one is perhaps not occurring naturally. This  can often be seen in editorial architectural photographs also in motor sport photography. In this case you have seen and interpreted this strong diagonal, which does have other diagonals within the image. This satisfies the assignment and 'ticks the box' but the image itself lacks a strong dynamic quality due in part to its busyness and unstructured shapes that are occurring. The image lacks context, you describe a narrative that attracted you to the picture but it is not evident in the picture itself. The white cloud is interesting as it adds an ambiguity but I find it distracting.

6. Curves. This is a well seen image and the macro technique works hard exploiting the natural geometry and form of the plant. I like the ambiguity of this picture as it requires thought and investigation from the viewer. These subtle curved  shapes have an intrinsic elegance which you successfully make use of within your framing. Great use of shallow DoF. I will criticise the slight lining up with the foreground leaf and the way it 'just' intersects the curve on the left. Careful observing (can be difficult at macro level) of how shapes and lines intersect need to become an important addition to 'seeing' an image. Try to get lines and shapes to intersect on purpose or look for a viewpoint that will avoid that occurring. If they do intersect then make sure, if possible, that they do not 'just' touch but demonstrate a deliberate overlap. So in this case the slight intersection becomes distracting if it crossed into the curve very slightly more it would be less distracting, this may mean moving the camera just 2mm (at macro) to the left before shooting but not enough to lose the small amount of white background showing. At macro level all movements become very small to  effect the final image quite dramatically.

7. Distinct, even if irregular, shapes. The two circles work well here and the insect breaks the rhythm of the petals quite successfully along with the petal at the bottom which is bent slightly.. I like the out of focus fern as a diagonal as this leads the eye into the central flower. I find the stem above the flower which travels out of the frame distracting, it would have been useful to remove this at the time of shooting. As mentioned above it is surprising how much attention to detail is required when shooting at macro level.

8. Shapes - light. Interesting composition and I really like the use of shadow which balances the subject and the strong lines of the tiles add a dynamic quality to the image. Your comments about the shapes are valid but I find the subject slightly confusing. What is the orange mesh? and are there some hidden labels or gift tags behind it? The leaves intersect with the mesh to make a large area that is confusing and difficult to look at. When shooting this style of still life photograph attention to detail is essential. Have a look at the still life work of Irving Penn, his work appears to be casually occurring but is in fact highly considered and constructed but retains a natural and casual look.
Not sure about your focus on this image as the front rose looks to be either slightly soft or it may have some camera shake or movement due to your 2 second exposure.

9. Shapes - Irregular. Good use of shallow DoF to isolate the subject. I like the curve of the pot that can be seen as this introduces some dynamic into the picture. The flower does poses an inverted triangle that works in the composition. The brown leaf that intersects the flower is distracting, again it is lacking in attention to detail. When you shoot apparently simple subjects they demand the utmost attention to detail from the photographer. The viewer has nothing to distract them or allow the eye to look at and enquire after - so they look very closely and critically at the subject, which needs to be perfect. The foreground leaves on the right work well on this as they are slightly ambiguous and interesting and help to direct the eye into the image, not so sure about the leaves on the left as the bottom one has the intersection problem as already mentioned in image 6 above.

10.Trapezoid. Well seen as a trapezoid and an interesting composition using that shape. The image is ok but for me looks like the type of image you may see on a packet of seeds from a garden company, it is a simple record of four flowers, as such it describes the flowers very well but lacks emotion or narrative. You describe an interesting narrative that led you to take the photograph while out walking but this is not evident in the actual picture. This often happens where images are not planned but just taken in passing. Think about the surroundings and the narrative you describe, how could you incorporate that into this picture?

11. Implied triangle 1. Well seen in terms of the triangle shape and I like the background on this, it is sufficiently out of focus not to be distracting yet holds interest in its ambiguous shapes. The viewer has to look and try to work out what is happening or where it was taken, the image starts to have a narrative, unlike the image 10 above. The main triangle works as a composition device in holding the three flowers together the second triangle of the leaf is simple and does help the composition by stopping the eye from drifting of the frame.

12. Implied triangle 2. A similar image to 11 and one that demonstrates an implied triangle. As above the out of focus shapes in the background are interesting and help the picture to start to have a narrative. Good rationale for choice of camera settings. This is a technically well presented and photographed image but lacks in originality or style. This really comes back to research and looking at other photographers work to inspire and inform you.

13. Rhythm. I like this image and rhythm is evident within the flowers, the rhythm creates a tempo or beat which allows the eye to travel through the  picture. What often works in photography is to break the rhythm at a suitable point in the composition - may often be on a third within the frame. In fact in this image the slightly blurry flowers caused by the wind? are starting to break the rhythm, you comment about should have used a faster ISO and shutter speed - think the opposite - use a tripod and a slower shutter speed so that you deliberately allow the wind to break the rhythm for you. This again comes down to planning and thinking ahead about what you want the image to say and achieve. I find the earth showing through at bottom left distracting and interrupts the pattern, slightly moving your viewpoint to avoid this would have produced a simpler and more effective image.

14. Pattern. Good use of natural patterns and textures and interesting sunlight on this picture. This helps create an atmospheric photograph which holds your attention. I like the dead leaves as they break the rhythm, I feel that there is too much space on the left, quite often when deliberately setting out to photograph pattern then filling the frame is an effective away of framing the image. I do quite like this space but it is slightly too much and the curly branch is too distracting and draws the eye away from the pattern. I am pleased you have commented about your focus issue - attention to detail Eider! In this case that leaf is actually the focal point of your image and should be the sharpest part!


Sketchbooks
Consider creating a scrapbook / sketchbook to collate images torn from magazines, flyers and brochures of exhibitions and gallery visits and other photographic ephemera. Combine this with some brief annotation and reflective thought and this will build into a valuable tool of reference and help to illustrate your learning journey. You should develop the habit of correctly referencing research material, provide details of the author, the source you obtained the information or image and include the date you accessed it. Ideally this should follow the Harvard Referencing method, details for this can be found on the OCA student website in the form of a PDF published by New Bucks. University.


Learning Logs/Critical essays
Well written and thoughtful reflective comments, I like the fact that you list the technical details and comment why you chose those settings, this is good practice. You now need to expand those comments to discuss how you think you could improve the shot and has it fulfilled the assignment criteria as well as it could? So you need to look at and inquire into your image more. I attach a Word document that has some bullet points on to help you start to criticise your own and others artworks.
You also now need to develop your research and critical appreciation of other photographers work. At degree level this is vital, you need to immerse yourself into the work of critically acclaimed photographers (historical and contemporary) and also look at the work of acknowledged emerging new talent. This work will start to 'inform' your own practice and should be referenced within your blog / log and commented upon how it may have led you to undertake a project with a certain direction or style. This route will enable your own style and direction to develop and make you much more aware of different creative approaches and genres which in turn will enhance your own creativity and develop your self confidence and direction. By noting this into your blog you will develop this as a valuable learning tool that will provide you with material and stimulate creativity and perhaps just as importantly will allow the assessors at the OCA to see how productive your journey through the course has been and provide an excellent indication as to your abilities.

As already mentioned the images you have produced are ok and tick the box's for the assignment but they appear to lack much in terms of planning and reference to others work. This would have let you experiment and take some 'risks' with your images by stimulating your own creativity, trying new techniques and pushing your creative boundaries.

Suggested reading/viewing

Explore Irving Penn's still life work. John Blakemore (tulips) and look at the flower photography of Robert Mapplethorpe. Robert was a very complex person and photographer,  he is often known for his very controversial depiction of his gay lifestyle which resulted in some quite shocking images. His flower photography is of a very sensitive and sculptural nature, it would be a good exercise for you to look at and indicate the shapes, triangles and points you can discover in Mapplethorpe's flower pictures and relate them back to your own.

This is a good starting point from the recommended OCA booklist:
Cotton, C. (2009) The Photograph as Contemporary Art (2nd revised edition). London: Thames & Hudson.

Here is a reference to a recent OCA 'Blog of the week'. Look at the two links as one is used for the research and planning of shoots.




When referencing and using others works of art within an educational context copyright issues may still arise. I attach some information on this.

Pointers for the next assignment

·      Expand commentary on the visual content of your images, has it fulfilled the assignment brief? How could you improve it? Why you like it or do not like it? Photography is about 'seeing'.
·      Try and avoid being too literal with the subject, develop 'seeing' and narrative. Plan and sketch ideas (keep in your log) in advance of the photography.
·      If you decide, on reflection, the image you take for an assignment is not quite right then allow time to shoot the photograph again, until you are happy with it. This may require returning to a location on another day, or waiting for the weather / time of day to produce a result that fulfils your vision.
·      At degree level it is vital to immerse yourself in imagery - good imagery. Look at the work of critically acclaimed photographers, you may wonder why some  are critically acclaimed so ask and debate those questions within your learning log and or blog.
(List of websites attached - use as a starting point)
·      Start to develop some visual references on your blog that point to research and images that inspire you.
·      This research should start to 'inform' your own practice so acknowledge this in your reflections.
·      Be aware of copyright issues in using images for research, Develop good habits about correctly referencing research material.
·      You must start to develop the research element of your work and include pointers, annotation and reflective comments to this within your learning log and blog.
·      Along with research is the obligation to reference the source material correctly. This is usually achieved by using a notation system developed by Harvard University. I attach a brief document about this and potential copyright issues. Further information is available as a PDF, published by New Bucks. University, from the OCA student website.
·      Send me some prints for assignment 3 including some from this assignment 2 - Email me when you send them so I am aware they may be coming.
·      Re-visit image 4, horizontal and vertical - publish this with a commentary on your blog and email me when you have done this.

Project 2: Elements of design

I had some doubts about choosing a subject for this project and finally, I selected the flowers and plants group. After having finished the project I have to tell that it was surprisingly fascinating the new world I've discovered.

So now let's explain the final compositions:


  • Single point dominating the composition.

Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/25   f/11
ISO 200. No flash, no tripod.
I found this flower in a windy afternoon. The wind was a little obstacle to get the picture, but it didn't stop me so finally I got the shot I wanted when the wind calmed. I set the aperture to f/11 because I wanted the whole purple flower to be sharp, specially the blue and yellow parts, while I wanted its backgroung blurry to focus the attention on the flower.

Here the flower is dominating the composition because its color is contrasting with the dominant green in the scene and in my opinion, it makes the photograph so beautiful.


  • Two points

Camera body: Nikon d90
Lens: Nikkor 70-300 mm f/4-5,6
Focal length: 200 mm
Exposure: 1/125   f/4,8
ISO 200. No flash, tripod used.

I saw a couple of plants growing in the edge of the road. I looked at them and realized that although their root was placed in the same point, one of them was riper than the other because one was completely red when the other had a gradient between green to red.

If we compare the two points in the scene (the two plants here), we can see that the left one has more contrast that the other because the right plant has some green as the background. So the main point here would be the red plant.

I chose a large aperture because I wanted to focus the attention on the two plants while I separated them from the background but I'm afraid of not having solve this problem because the camera was too close from the points.

The vertical framing and the lines drawn by their stems (also vertical) simbolize the idea of growth, which is emphasized by their colours because it means that the riper plant (the red one) has grown earlier.



  • Several point in a deliberate shape

Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 10 sec.   f/22
ISO 200. No flash, tripod used.

It has been by far the most difficult exercise in this project. I think that shooting to something you find in nature is easier than creating a situation that you like to get shot. And of course, you need more time (most times, depending on what you're shooting) to think the composition and to prepare it. 

What I most like about photography is when I've decided my subject and I start thinking about where to position the camera, think about if it's gonna be a low angle, high angle or eye level shot and so on. Here in this exercise the challenge was another one because first I placed the camera and chose the point of view and then started filling the frame. To be honest I didn't believe that I was able to get a great shot because I had no idea of how to begin. But when I placed the first point and then another one, and another one, my mind started viewing different shapes like triagles and curves that helped in the final composition.

  • A combination of vertical and horizontal lines
Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/80   f/5,6
ISO 200. No flash, no tripod.

I was photographing a flower near this leaves when I saw it and I liked its highly saturated green colour against the stone so it got my attention very soon. The tricky part of getting the picture was that it was in the border of the river so I had to think about how I was going to place myself to get this point of view. Finally I decided to take a bird's eye shot. If there is any problem in this picture is that the foreground leaves are a distraction, but I there was nothing to do with them.

The combination of vertical and horizontal lines help to lead the eye in the right direction and make to look throught the image.

  • Diagonals 
Camera body: Nikon d90
Lens: Nikkor 70-300 mm f/4-5,6
Focal length: 70 mm
Exposure: 1/1250   f/4,5
ISO 200. No flash, no tripod.

I took this shot when I was going back home after a walk. I heard some birds and looked up when I saw some branches iluminated by a warm summer light and I became a little nostalgic so I got the idea about the composition of the shot. I chose a branch to be my diagonal I placed creating  a triangle with the edges of the frame to give more power to the picture. 

Here the main diagonal works pretty well to draw the eye through the image.  But there are also a lot of more diagonals in the picture drawn by smaller branches and leaves. They intersect with other diagonals creating a sense of action because the lines make the picture confusing.


  • Curves
Camera body: Nikon d90
Lens: Tamron 90 mm f/2,8
Exposure: 1/100   f/11
ISO 200. No flash, tripod used.


This is a plant's close up. I took out my camera and the tripod to the balcony and started experimenting with the macro lens. It was rainning so I wasn't very interested in taking pictures with such a gloomy environment. After a while, the sun appeared and I took this picture because I liked how the stems' "hairs" were iluminated by the sun as well as I liked its light curved shape. 
The only problem is the distracting leave on the top left corner because it's not in focus altough I used a small aperture the macro lens is a little bit more difficult to work with. 

  • Distinct, even if irregular, shapes

Camera body: Nikon d90
Lens: 70-300 mm f/4-5,6
Focal length: 300 mm
Exposure: 1/400   f/11
ISO 400. No flash, no tripod.

I was photographing the daisy when I realized that it was a small insect in it, so I used the telephoto lens. Here we can see two circles: the outer circle is implied  by the petals and the inner one is real (yellow). 

As when using circles in a composition, they attract the whole attention, so I tried to place it in the middle to balance the composition.

Camera body: Nikon d90
Lens: Nikkor 18-55 mm f/3,5-5,6
Focal length: 48 mm
Exposure: 2 sec.  f/16
ISO 200. No flash, tripod used.


Here I used the shape of a rose in the composition. The shape creates another element in the picture for the viewer eye to look through and helps to fill the frame.

Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/60   f/16
ISO 200. No flash, tripod used.
This flower's irregular shape captured my attention as well as its saturated color. I tried to focus the whole plant while blurring the background so the shape of the flower gets sharper and draws an inverted triangle.

Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/125   f/11   EV-1
ISO 200. No flash, no tripod.

I found this plant containing four flowers when I went for a walk. It was very windy that afternoon so the flowers didn't stop moving. I needed a quick shutter speed to freeze their movement as the same time I needed the flowers to be in focus. I also was afraid of the exposure because the flowers are nearly white and I didn't want to overexpose them, so I set the exposure compensation to   -1. 

Here the flowers draw a trapezoid and the hanging pistils are lines suggesting movement because of their direction: the upper flowers' pistils make a curve towards the right bottom flower.

  • At least two kinds of implied triagles 
Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/500   f/5,6   EV -1
ISO 200. No flash, no used.
I composed the image to get one flower higher than the other two, while these were at the same heigth, so the implied traingle with the appex at the top is quite obvious here.

It's another triangle in this shot just in the top. But this one is a real triangle because it's the shape of the green leaf.

If we take another look to the image, an oval can be seen also. We can see the top flower inside the oval, so it attacts the viewer's eye to it.

I've used a large aperture to separate the flowers from the background and lead the eye to them, because the contrast between the white cover and the pink flowers has a lot of power in the picture.  

Camera body: Nikon d90
Lens: Tamron 90 mm Macro f/2,8
Exposure: 1/400   f/11
ISO 200. No flash, tripod used.

In this picture the implied triangle is also drawn by the three flowers but I think the appex is inverted (the centre of the bottom red flower), so it would be a triangle built in perspective.  

Although the dominant point is the pink flower because it is larger and the color is different from the others. Other reasons would be that it's placed following the rule of thirds and it's shape can be seen better.

I used this aperture because I wanted sharpness for the three flowers but I also wanted to separate the background and to blur it.

  • Rhythm
Camera body: Nikon d90
Lens: Nikkor 70-300 mm f/4-5,6
Focal length: 70 mm
Exposure: 1/30   f/16
ISO 200. No flash, tripod used.

I don't understand very well the difference between rhythm and pattern. Well, I know in theory that rhythm is related to movement while pattern is static but in practice I don't see much difference sometimes. 

I took this picture, which I think is an example os rhythm because I think the eye moves around the picture getting a sense of depth. To get this sense of depth I used a small aperture, such as f/16, which gave me a shutter speed of 1/30. This was a little bit dangerous speed because it was slow in my opinion, and that's why  some flowers in the picture are blurry. 

Now that I'm lookin at the picture, I'm asking myself why I didn't set a higher ISO to get a faster shutter speed.



  • Pattern
Camera body: Nikon d90
Lens: Nikkor 70-300 mm f/4-5,6
Focal length: 135 mm
Exposure: 1/60   f/11   EV -1
ISO 200. No flash, no used.
This is my example of pattern. I've chosen a repetition of different leaves which gives me a static sense. I chose a f/11 aperture to get everything in focus and I thought it was when I checked in the camera viewer but when I reached home and loaded the picture in my laptop I saw the dark green leave in the upper right side wasn't sharp enough. 


Exercise: Rhythm and Pattern

To be honest, I've to tell that I haven't understood the difference between rhythm and pattern yet. I know that in rhythm the eye follow a direction and pattern is a more static concept but I find them very similar.

I've chosen this picture for rhythm because I see a dynamic repetition in the opened windows and they create diagonal lines as the eye crosses the image from side to side.

Camera body: Nikon d90
Lens: Nikkor 70-300 mm f/4-5,6
Focal length: 190 mm
Exposure: 1/160   f/8
ISO 200. No flash, no tripod.













For "pattern" I've selected the following photograph. It's a detail from the Vatican ceiling. I cropped it to leave outside the frame the ceiling edges, so the repetitive tiles fill the frame. 

Camera body: Nikon d90
Lens: Nikkor 18-55 mm f/3,5-5,6
Focal length: 18 mm
Exposure: 1/125   f/5
ISO 400. No flash, no tripod.

Exercise: Real and implied triangles

  1. Triangular subject. I found this fountain in the Peterhof Gardens. It reminds me to the Christams tree because of its triangular shape which is more evident because I used a slow shutter speed to show the water movement.

    Camera body: Nikon d90
    Lens: Nikkor 18-55 f/3,5-5,6
    Focal length: 18 mm
    Exposure: 1/60   f/22
    ISO 640. No flash, no tripod.

  2. Triangle by perspective, converging towards the top of the frame. I've used an old style narrow street as my subject in this picture and I've placed myself in the middle of the street to converge the lines as they go away and draw a triangular shape.

    Camera body: Nikon d90
    Lens: Nikkor 18-55 f/3,5-5,6
    Focal length: 24 mm
    Exposure: 1/15   f/8
    ISO 200. No flash, no tripod.

  3. Inverted triangle by perspective, converging towards the bottom of the frame. I've choosen this picture taken in the Chicen Itza's surroundings. The picture cold be included also in the category described above (triangle created by perspective converging towards the top) if we pay attention to the piles and the floor, but in this case the saturated sky contrasts with the grey stone pile and the shape of the triangle is very marked as we can see. This effect would be clearer if the trees on the right wouldn't there. 
Camera body: Nikon d90
Lens: Nikkor 18-55 f/3,5-5,6
Focal length: 18 mm
Exposure: 1/4000   f/3,5
ISO 200. No flash, no tripod.

1- Still-life arrangement to produce a triangle with the apex at the   top.



Camera body: Nikon d90
Lens: Nikkor 18-55 mm f/3,5-5,6
Focal length: 30 mm
Exposure: 1/8   f/4,2
ISO 200. No flash, no tripod.



The triangle is drawn by the black rounded parasol and black the light meter to the blue glasscase which forms the appex of the triangle; so the appex is at the top.

 2- Still-life arrangement with the apex at the bottom.

Camera body: Nikon d90
