Before leaving Exercise 3.2 and the representation of motion, I will post a few examples of some of my earlier (pre-OCA) experiments.
The first image is not, strictly, a multiple exposure but a sequence of images (1/1000s with the camera in ‘machine gun’ mode) montaged in Photoshop. The focus blur on the rearmost image is accidental but seems to ‘work’. My montaging technique is not perfect, so there is some uneven colour in the sky around the kite-lines.
The next set is of an Irish Coastguard helicopter that was doing training exercises with a car ferry that I was travelling on, which gave me the chance to experiment with the effect of shutter speed on the rotors are depicted. In the first image, at 1/1000s, the main rotor is ‘frozen’ which gives the uncomfortable feeling that the engine has failed and the helicopter is about to fall out of the sky
At 1/400 we see some blur but the rotor is still effectively static. At 1/15s we lose it almost completely. The intermediate images with shutter speeds of 1/100s to 1/50s work best for me.
Slow shutter speeds and moving people can produce results ranging from delightful to bizarre, with quite a lot of ‘interesting’ in between. The two dancer images have exposure times of 0.8 secs, resulting from the very low light in the hall, but which capture the movement of the veils (which is the object of this dance)
In crowd scenes with an exposure of about 1/2s as with the examples below, people walking will blur but not disappear. This sort of image emphasises the stationary people and is a way of emphasising stillness in the middle of bustle.
Shutter speed is critical as there is a very odd effect which occurs at exposure times of 1-2 seconds. No matter how fast a walking or running person is moving, the foot on the ground is stationary. At these shutter speeds, a moving crowd becomes a sort of fog full of disembodied feet, which is very disturbing.
The final image is made with a pinhole camera and an exposure of 5 minutes. This is Maidstone’s main shopping street on the weekend before Christmas. The grey ‘fog is a crowd of moving shoppers. Only the group taking a breather are recognisable.
