This is the image you referred to:  and I can see where the "grainy" comments come from. However I don't think it has anything to do with resizing the image. Perhaps the image was underexposed to begin with and you boosted the exposure, or maybe you pushed certain colours or contrast too much? I can't tell without seeing the original.
It's certainly not a common thing in your workflow - none of your other images that I checked have the same issue.
Does the image look OK on your screen, do you not see the reason for the graininess comments? If so, try looking at it on a different computer, perhaps your screen is off. |
