The images in this posting continue my Exercise 3.2 work, but viewing clouds in motion rather than water. I was fortunate enough to visit the Angel of the North on a breezy day with broken cloud. My viewpoint is downwind of the Angel, with the intention that the clouds would be advancing toward me.
The first set of images, effectively, repeat the water exercise with single exposures at shutter speeds between 1/800s and 40 secs.
Clouds are slower-moving than water and I saw no significant blur at shutter speeds faster than 1 second. The 20- and 40 second images give an impression of motion but introduce a second problem, clouds have rather softer definition than water and the motion blur tends to smudge into a featureless highlight.
In the final two images below, I have used the E-30’s multiple exposure facility to capture four images on a single frame in-camera. A function named ‘automatic gain control’ has handled the issue of total exposure, presumably by reducing the effective ISO sensitivity.
The second version, with multiple short exposures gives the best definition but a sense of staccato movement. My preference is for the first image, combining reasonable definition with some motion blur.
