I've noticed that if I take digital images involving a plain or single colour eg, blue sky, a white table top, etc it looks pixelated. How should I describe it... For eg, in an image with a blue sky I get these concentric lines appearing across the sky with slightly different gradients of blue.
Hope I make sense above. I don't think it's bcos of the resolution (It's quite high anyway) bcos the other subjects within the same image appear acceptable.
Is it bcos of the screen resolution? Even if so, how come it only affects uniform colours but not others?
