Firstly, I purchased a forest scene online and changed its colour scheme and lighting. The fog and ambient lights were applied according to the parameter values set by the fog_test I had done earlier.
Then I added two lights to the wolf’s eyes, trying to achieve a sense of darkness that cast a faint light. This scene expresses the patient’s mood when he is in a state of depression, and I added two point sources of light to express that although one is in darkness, there is always a little light to fing.
Then I discovered that I could set key frames in the Aifog where the parameter values were adjusted. This allows the size of the fog concentration to be adjusted as the shot and the feeling of expression requires, creating a visual change.
Then I composited this short test image in adobe after effects and cranked the speed in premiere pro to find the most appropriate timing for the change.
