Normal map is a kind of texture used in 3D modeling, which can map 3D information to 2D planes, restore part of the 3D bump and height information on 2D planes, with a perceptual sense of traversing space. I have been recently working on modeling, and use normal maps quite often, so I was touched by its bluish, clean and clear color experience. Therefore, I had a try, to craft ordinary photos into the style of Normal. The performance of Normal style on everyday pictures produced the exact opposite effect of its original function - flattening and symbolizing the information in three-dimensional space. As far as I am concerned, the photos are visually pleasing and have a mischievous and playful feeling.
