I'm very new in the world of photography, and I want to know the name of this problem.

enter image description here

I know there is a word and I searched but I could not find it. If someone knows the word then please enlighten me.

That's color banding. It can be caused by posterization due to insufficient bit depth for smooth gradations in a small color range ­— or can be a common artifact of JPEG compression.

  • While 95% of the things on this site that people mistake for color banding is not color banding, this really is (and is a clearer example than in the linked duplicate)! – thomasrutter Dec 12 '17 at 00:32
