The effect is created in camera normally. However using After Effects something similar can be created from either moving video or time-lapse.
This video was recorded within the college using a tripod. The interval was one image per 3 seconds and the exposure was 1/15 to obtain blur to reduce flickering.
The resultant images were uploaded as a sequence to Adobe After Effects and dragged into a composition.
An adjustment layer was created.
I feel I am starting to feel more at home using this programme and it is gradually revealing more secrets. It does however, continue to frustrate when it does unexpected and the solution is difficult to find working independently.
