I've got two photos rejected due to the different reasons. It's confusing because both of them have been shot with the same camera settings and the same lighting conditions (shot in the same direction within few minutes, so lighting conditions are identical). Image size and compression settings are the same as well.
Rejection reason of first photo: color soft
I don't understand what is wrong with color here - is it oversaturated or white balance adjustment is wrong ?
What must be sharpened to fix softness rejection?
Rejection reason of second photo: grainy compression
I don't find what areas should be corrected to fix grainy rejection - sky or aircraft surfaces ? Compression rejection is also confusing because compression settings are the same as in all recently uploaded my photos.
Your opinions will be appreciated.
