Exercise: Primary Colours

In this exercise we are asked to take 6 images, 3 of which are dominated by the primary colours ( red, blue & yellow) and 3 dominated by the secondary colours (violet, green and orange). Furthermore each photo is to be taken with auto bracketing for -0.5 stops and + 0.5 stops as well as the metered value of 0 stops. To make this more palatable for blogger I have split this exercise into two for primary and secondary colours

We are then to take the exposure that matches the primary / secondary colour that is shown  on our colour chart on page 87 of the course notes.

My normal camera set up is to have a non-default of zero compensation for contrast and saturation, I normally then add this during the raw conversion as required. For this exercise I chose not to change any of the default raw settings giving an 'as shot' version of the colours i.e. with no boost to contrast or saturation.

Primary Colours


For the first exposure I was not sure which one really captured the red on the circle, it certainly was not the over exposed shot, not much in it but if I were to choose then it would be the one taken at -0.5 stop, slightly under exposured.


Blue definitely looks more intense under exposed and I have no reserves on choosing the under exposed shot here.


The final colour of this exercise is yellow, again I took advantage of a brightly coloured flower. In this the final example, I have to plump for the over exposed  image. The yellow in the book and the yellow of this flower are both bright and vibrant and this is the closest match by a mile, so for the final image I would choose over-exposed.

Exercise: Secondary Colours

This is the second part of the exercise showing secondary colours

Secondary Colours


Violet was hard to find and I had to resort to a close up of a flower. In this particular example I think that the normal exposure is the closest to the purple on the ring.


For orange I chose a wall that contained some very orange bricks, they were used with red brick to make a pattern. Again, I think that that colour that matches the examples is the one without any exposure compensation. The under exposed image looks too drab and the over exposed too washed out.


Again green looks more like the circle in the most under exposed form of a picture of a fig leaf. I took this one because of the lines and curves, does this mean I am learning? It seems that so far all the primary colours look best under exposed!

Exercise: Control the strength of a colour

This is the first exercise of the section on 'Colours'. This was one of the sections that drew me towards this course and I am pleased I am now starting it.

In this exercise we are invited to explore the effects of colour by controlling or manually adjusting the exposure. We are asked to take 5 photos of the same image by varying exposures, these range from the metered value to +0.5 stops and +1 stop and - 0.5 stops and - stop. I took five images of a brightly coloured kitchen cleaning product trying the fill the frame as much as possible. 

The first image was taken at -1 stop off the metered value at an aperture of 4.0, the exposures are then increased  by 0.5 a stop each time giving he range of 4.0,4.5,5.6,6.3 and 8.0, the metered value being 5.6.

Obviously the less light that is reflected from the object on to the cameras sensor will will means that its brightness is lower, but we are asked to comment on how this affects the 'colour'. It can clearly be seen that the over exposed images (lower aperture) do not have the same level of richness or intensity of the image at the standard metering, and those images that are under exposed (higher aperture settings) have a much more intense appearance, giving a more saturated or richer feel to them, this is maybe more evident in the red rather than the orange parts of the image.

I therefore feel that this exercise is demonstrating to us that we can control the level of saturation of colour in an image by under-exposing the shot. Of course this can also be done post processing of the image, but I think that the same level of moodiness would be lost, therefore quite an interesting concept that I was unaware of until now.

Assignment 2 Complete with Feedback

I took too long in getting the second assignment completed. I found this section harder than the first  and I had less time but overall I am pleased with the results and my tutors comments. I must however think more of what the image is saying and be more descriptive on the narrative.

I have learnt a lot from this section - to be honest I think that all of it was new to me and I will try and employ the techniques used here for the rest of this course, it is now just a question of automating the processes....

I have also published the Assignment at should anyone wish to view these. I will also try and get the Assignment 1 images up there as well.

I have already started taking photos for the next section 'Colours' this looks a lot more intuitive to me and I already understand many of the concepts - so here's to getting this one finished earlier.....

Exercise: Rhythm & Pattern

I found this exercise interesting and something I had considered before but with no real thought. Now that I understand the concepts I will look for more types of these shots as I find them very interesting.

For this exercise we are two produce an image for a pattern and rhythm. Rhythm having that optical beat that the eye would follow through an image.

For rhythm I chose  a number of interesting slippers hanging off a wall. I guess this could also be described as a pattern, however I find that the eye does follow the slippers around. Also the notes indicate that a pattern should not have depth of field for which this image does, concentrating the viewer on the in-focussed slippers.

My second image, representing pattern, was of a penny fall in an amusement arcade. This is quite a messy image and I could have cropped it closer just to the coins but I decided I wanted to keep it as is representing one section of the machine.

Exercise: Real & Implied Triangles

This exercise explores the shapes of triangles which are often considered to be the strongest of shapes within a photograph. In this exercise we are asked to produce 6 photographs, the first is of an object that itself is triangular. For this I chose a landscape with some triangular trees.

The second image is of a triangle made by perspective converging towards towards the top of the frame. For this image I used three flowers grouped together to make the triangle pointing towards the top of the frame.

The next was an inverted triangle, this one was a lot harder as most of the natural triangles tend to point towards the top of the frame. Then I saw my son climbing a couple of trees and moved towards the left to make a triangle by perspective that points towards the bottom of the frame.

Then I found another shot by cropping another effort of making an inverted triangle of a fairground ride...

The next set of images are to be implied triangles using a still life arrangement to produce a triangle with the apex at the top of the image and the second at the bottom of the image. For this I used some colourful kitchen ornaments and arranged them as required. I think that the first is a much better, more balanced image than the latter. In the last the central pot looks drowned out and not in harmony with the other two vessels.

Finally, we are to arrange three people on a group picture in such a way that the faces or the lines of their bodies make a triangle. This proves to be a very easy yet successful way of making a portrait that I had not considered before.
