Your perception of time is skewed by what you see

When people look at larger, less cluttered scenes — a big, empty warehouse, for example — they think they viewed it for longer than they actually did. Similarly, people experience time constriction when looking at more constrained, cluttered scenes, such as an image of a well-stocked cupboard. The study of 52 participants also showed that people are more likely to remember the images they thought they viewed for longer.
