Visual Effects: Colors, Contrasts, and Perception

The video tutorial explores how visual effects can be created using simple patterns like concentric rings, leading to phenomena such as moiré patterns. It delves into contrast adaptation, explaining how high contrast can temporarily alter perception, using a bike image as an example. The tutorial also examines how varying contrasts in images can mislead our perception of sharpness and size. Finally, it discusses how context can change our perception of brightness and shapes, highlighting the brain's role in visual interpretation.
