This is Glaze. The tool that protects images from ai. Unfortunately, to protect the image, it must be changed. Sorry but no. I'm the first of being in pain for this, but is not what I call 'imperceptible to the eye' changes. #noai

The only use I could reccomend to this tool, is that if you make #digitalilustration, and you are making a commission, and the client asks you for an early sketch, you could use this as a watermark to protect it. So he doesn't use ai to finish your sketch and cease to contact you.
