Exercise: Cloudy weather and rain.

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. 

ISO 100 f/5.0 1/160s

ISO 100 f/4.8 1/250s

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.


ISO 1250, f/9.0, 1/125

ISO 140 f/8 1/125

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.


ISO 360 f/8 1/125s

ISO 100 f/8 1/350s

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. 

This image demonstrates how the diffuse light of a cloudy day penetrates every nook and cranny rather than having areas deep in shadow or brightly lit.

As with the image above it, this second image is evenly lit, meaning that even the darker areas are visible without the lighter areas being blown out.

I used this image firstly because it was a bright cloudy day so fit the brief perfectly, and secondly because it is a good example of how a building is lit very differently when there isn't a direct light source, such as the sun ona clear day. This building would certainly have much lighter and much darker areas pretty much throughout the day on a clear sunny day.

The third part of the exercise requires me to take 2 images in rainy conditions.

I liked this image as it shows the evidence of rain in droplets on the saddles as well as indirectly by the reluctance of people to rent the bikes when the weather is bad. Also there's a rhythm to the saddle heights which I found quite attractive.

A stream (probably a little too out of focus) has appeared after heavy rain in Sheffield. There is evidence also in the droplets of rainwater on the handrail.
