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!

Notes:

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.


Red

250mm

f/5.6

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

Yellow

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.

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

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.

Blue

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

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. http://grahambakerphotography.com/


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.
