Secondary colours

This is part two of this exercise to produce images dominated by one of the primary and secondary colours.


All of this set  was taken on different locations and under various light conditions. I have noted the shot details for each of the colours.




1/6 sec

ISO 100
The green set was taken at some nearby woods, on a bright sunny day with no clouds and using the camera set on a tripod to maintain a consistent viewpoint . I maintained a focal length, aperture and ISO any changing the shutter speed to adjust the exposure. I was going to try to find a more ‘pure green but as suggested in the course text; I tried to find more natural occurrences. When you look at the trees generally our brains see the green whereas in reality trees are made up of many shades of green and many other hues.



1/8 sec

ISO 100
This second image was the ‘average’ exposure for the scene



1/10 sec

ISO 100

This is the darkest of the 3 images (half-stop exposure difference of shutter speed) being the fastest shutter speed. The differences in the 3 exposures appear to be very subtle compared to other similar shots I’ve taken. Although the differences can be more clearly seen in the image below.


55mm f/5/6 0.3 sec ISO 100
Out of all the sets in this exercise I like the violet ones the best. The image is of a towel taken indoors with light coming through a window from the right side of the scene; I used a tripod to maintain the same viewpoint and as I like to shoot in the lowest ISO using the tripod reduced the chance of camera shake at such slow speeds. I just really like the abstract feel to it and the way the textures and depth of view make it more interesting for the eye.
55mm f/5/6 1/4 sec ISO 100

55mm f/5/6 1/6 sec ISO 100
Again the differences were quite subtle for the half-stop differences although clearer than the tree shots. I’ve created another version below so that they can be compared next to each other and you can see the differences more clearly


84mm f/11 1/125 sec ISO 100
This shot is my least interesting to be honest. It is the seat of my daughter’s swing in the back garden, however it serves the purpose of the exercise in filling the frame as much as possible with orange. The image was taken on a bright sunny day with no clouds and I used the camera on a tripod and framed it in camera (although the swing did move slightly in the wind for each shot). I found that the differences in the exposures clearer show the levels of saturation much clearer in this set, compared to the average exposed shot (below) this first shot has a faded weak colour.
84mm f/11 1/180 sec ISO 100

This was the averaged exposed image

84mm f/11 1/250 sec ISO 100

The fastest shutter has created the image with the most depth of saturation and the least brightness of the orange hue

As with the previous posts I’m still struggling to stay as focussed on the colour section. I’m not saying I’m not making progress with it, but just that progress is slow in relation to to. It’s been a busy time recently with my daughters birthday and starting a new job as well as some personal photography projects (still to be written up for blog!)that I’ve been exploring. While I don’t mean this to be an excuse for not being ‘on the ball’ with this section I “am” taking longer than I have during other exercises, so it’s a case of being patient with me for a while longer…

Primary colours

The idea behind this exercise is to produce some images that are dominated by one of the primary and secondary colours. To make the exercise more interesting it was suggested to take different exposures of the same subject and identifying one of these as matching its corresponding colour on a  standard colour wheel.

I’ve broken this exercise into 2 parts. The reason being how long I’ve spent on this! since the last assignment other distractions have taken priority and I have been unable to concentrate as much time to the course. Added to which the line ‘take your time and don’t rush’ from the course text played on my mind and made it an excuse for not putting as much time in..

Anyway enough of the excuses; I’ve added the ‘Primary’ colours in this update and will add the ‘Secondary colours’ when I finish it!


All the colour sets are taken on different days and locations. I have used the same ISO and lens (although different focal lengths) throughout in order to keep some consistency; For the Red and Yellow photo sets I took the shots handheld and the blue set I used a tripod.




1/125 sec

ISO 400

This is the second shot I took in the ‘red’ set. I’ve placed the images in order of exposure though (this is the same through this exercise). Keeping the shutter speed constant this image is with the widest aperture. You can see the edges of the petals are paler than the other 2 images
250mm f/6.7 1/125 sec ISO 400

This image was the first shot and I took the exposure level from the camera (exposing the aperture from a manual setting of 1/125) you can see that it is less pale that the image with wider aperture
250mm f/8 1/125 sec ISO 400

This last image is with the smallest aperture of the set and the petal leaves have a much greater saturation and depth of the red. To me this is the more ‘satisfying’ red of the 3 images


225mm f/13 1/125 sec ISO 400

For this set rather than change the exposure setting for the aperture, I kept this constant and changed the speed, just to show a different approach to the exposure settings. In this first image (second one taken in the set) the yellow is bright and especially around the edges has started to lose detail in the highlights.

225mm f/13 1/180 sec ISO 400

As the shutter speed has increased, the yellow has become more satisfying colour with a better balance of detail in the highlights 

225mm f/13 1/250 sec ISO 400

The third version where the shutter speed has increased further the yellow has become flat and lacks contrast; although the image is still apparent as yellow it lacks the vibrancy of the middle image.


55mm f/6.7 1/60 sec ISO 400

The image is of some curtains at home. This time I went back to changing the aperture and keeping the speed constant. This shot was with the largest aperture. I liked the use of the curtains as the folds and patterns created different ‘blues’ to be compared for the different exposures. The wider aperture produced the lighter of all the images

55mm f/8 1/60 sec ISO 400

With the smaller aperture the lightness was subdued however the detail is still clear in the pattern and stitching of the blue material

55mm f/9.5 1/60 sec ISO 400

For the final image with the smaller aperture the centre of the image is close to losing  shadow detail, any further and the shadow could turn black.

As noted above I’ve struggle to concentrate on this exercise, leaving too much time between taking shots and I’ve still got to do the second half of this for the secondary colours! I’m wandering if I’m trying too hard at the moment, but having said that it has still been interesting.

Building a library of colours

The next section is about assembling a colour collection of photographs that are dominated by a single or distinct colour. The idea being to ‘train’ myself in recognising colours and becoming more sensitive to it in photography
