Exercise 32 Cloudy Weather and Rain

This is a multi part exercise. In part one we are asked to look at how exposure changes between sunlight and shadow caused by cloud. the following series of photographs show this change in a landscape.

Fig 01 Clouded Over - 1/125 at f14, - .67 stops, ISO 100

Fig 01 Cloud – 1/125 at f14, – .67 stops, ISO 100

Fig.02 Sun Breaking Through - 1/160 at f/14, -.67 stops, ISO 100

Fig.02 Sun Breaking Through – 1/160 at f/14, -.67 stops, ISO 100

Fig. 03 Sun - 1/200 at f14, -.67 stops, ISO 100

Fig. 03 Sun – 1/200 at f14, -.67 stops, ISO 100

Fig. 04 Shade 5 hours later - 1/60 at f/16, -.67 stops, ISO 110

Fig. 04 Shade 5 hours later – 1/60 at f/16, -.67 stops, ISO 110

This part of the exercise shows that cloud cover, even on a sunny day, significantly impacts exposure. There is a 2 stop difference between the same scene lit with full sun and when the sun is covered by cloud. There is a further 3 stop difference between shade at 11 am and shade at 5 pm. The dark marks in the sky in fig. 04 are swallows.

The third part of the exercise asks us to take photographs in the rain.
