I'm wondering why this picture is so grainy. It was shot at f16, 1/125 seconds, with an ISO of 100. I underexposed it to maintain the highlights in the sky but that is what I always do, and it doesn't end up looking like this! I edited it as I normally do in camera raw/photoshop, but I didn't take any other measures in post because I just wasn't sure what to do about it there, either. It seems unsalvageable. The other ones in the batch seem to be showing signs of grain, also. So I would like input on how to
- prevent this from happening
- ameliorate the situation in post, if it does.
Thank you! @null, I managed to add another photo. It is grainy--sorry, noisy!--also, but not as bad. It was shot at 1/160 seconds, at f/16 and ISO 100. Looking at the histogram I now see that they really are too underexposed--sorry to have bothered everyone with such an easy question! Never had so much noise before in landscape and I sort of panicked rather than putting on my thinking cap!
