In the first part of this exercise, I took three images of a hanging basket, with the images taken in sunlight being significantly more yellow. Undoubtedly, the sunshine shots look warmer, ans I think I would have changed the the white balance on the shaded image. Compare the original and the same shot with white balance moved to +19:
The right hand image looks considerably more like the image taken in full sun, albeit without the texture. I think in this case, it looks warmer and more natural. It does emphasise the power of the white balance adjustment tool in Photoshop RAW.
For the second part of this exercise, we are required to consider what corrections might be required in a scene. This time I took three images of the same subject in the high sun, shade, and low sun scenes as before but this time took three images, one with white balance daylight setting, one with shade setting, and one at Auto.
Taking a cue from the example in the notes, I chose an artificial flower arrangement on the dining table,
The first group of three were shot in high sun:
 |
| Auto WB f13; 1/125 |
 |
| Daylight WB f11; 1/125 |
 |
| Shade WB f13; 1/125 |
There is little difference in appearance between the daylight and auto settings, although the table looks warmer in daylight shot. The shade setting looks warmer, in fact quite close to the evening shot (see below) and is my favourite - the enhanced orange suiting this image.
Next, the arrangement was moved to the right, into the shade and the same sequence repeated:
 |
| Daylight WB f9.5; 1/125 |
 |
| Auto WB f9.5; 1/125 |
 |
| Shade WB f6.7; 1/125 |
In this case the image simply does not work without a shade setting, and even then the detail of the flower is lost. In this respect, this is a slightly false image; in reality I cannot think why one would take this image without some light enhancement on the flower.
Lastly, three images taken in late sun:
 |
| Auto WB f13; 1/125 |
 |
| Daylight WB f11; 1/125 |
 |
| Shade WB f13; 1/125 |
In this case, the image taken with Shade White Balance is too orange - it looks as if the shot has been saturated clumsily. The daylight shot looks a little flat and yellow; auto probably gives the most natural and appealing shot.
This exercise emphasised the importance of white balance, in particular how it makes the light relate to the colour of the image.
