Visual Experiment: Keep on Increasing Contrast, Gaussian Blur, and Inversing the Photo
A fun experiment I’ve been doing in Procreate on my iPad:
Choose a photo I like, then keep adding contrast, Gaussian blur, and inversing the photo and seeing what happens to the image.
This is what happened:
Thoughts:
- All shapes and forms eventually abstract into a simple and curved shape.
- We don’t actually perceive straight lines as straight — eventually with enough blur and distance, they are perceived as curved blobs.
