Hi all,
I recently have had several pictures screen and rejected, and there are 2 of the reasons which I don't understand what's wrong:
Digital noise is visible. Grainy sky.
Here is an example picture that sees the problems:

I just wanted to say that despite noise and grainy skies I have no clue how/why they occur. They've only become obvious after post editing and typical edits such as added saturation and cropping. In my original RAW picture these noises were almost invisible. The ISO setting was also extremely low when taking these shots - ISO250, f/8. What's wrong with it please? Is there anything I could do about it at all please?
Advice appreciated.
Thanks a lot,
Alex Fung
