In this exercise we look at how cloudy weather impacts on light levels and exposure values. Also how the diffuse light of a cloudy day allows subjects to be lit more evenly and from more angles than on a sunny day, when bright sunlight is much more focussed in one particular direction, creating shadows. I have also been asked to show images of rain and rainy weather.
The first part of the exercise requires me to take 3 pairs of images; each pair should have one image taken in sunlight and one under cloud.
Interestingly the above images have very similar exposure values. In actual fact, looking at the image on the right, I'm wondering if I had a polarising filter on the lens as it is only 1/3 stop lighter and should in theory be at least 2 stops. The lack of reflection from the water, and the change in depth of blue in the sky from left to right suggests that this is the reason for the similar EVs.
This is a bit more as should be expected ... the difference between the two images here is 3 stops. Clearly the situation on the right is the brighter of the two.
In the final pair the image on the right is again around 3 stops lighter.
The second part of the exercise requires me to take 3 photographs in overcast conditions where the diffuse light illuminates parts of the image where direct bright sunlight might create dark shadows.
The third part of the exercise requires me to take 2 images in rainy conditions.
