Whats up with this

Okay. I have no idea why but all my shots from this morning were pixelated/ had terrible noise. I shot most of them with a low ISO, normal length exposures which I thought was the main cause of grain etc. Does anyone have any advice on what could have caused it? I took photos of everything from lightning to rainbows to the sunrise and they all had it. Thanks in advance.

WONDERFUL picture! I looked at it at full size, 4,160 pixels wide...to me that looks like the detail smearing/smudging that is caused by High ISO noise reduction. I have not pulled the file into an EXIF reader, since this computer does not have one, but I can spot High ISO noise reduction without it. My guess is the camera's ISO was set very high.

Thank you for the reply…it looked like that to me too, but I'm positive my ISO was 200 ( I went back and checked just to be sure ). Any other ideas? I'm drawing a blank. So frustrating.

Yep... 200 ISO according to the EXIF data; did you try and increase the exposure in post? That can often lead to nasty noise in the image, especially in the blue channel.

Was this severely under-exposed in-camera? Did you perhaps have a lot of Minus exposure compensation dialed in?

Do you have in-camera Noise Reduction set to HIGH? What is the camera model? This is a simply dreadful image quality from a technical standpoint...from a pictorial point of view, I think it's very lovely, and really a nice shot, but the pixel-level detail looks like some heavy-duty noise reduction has been applied...there is that weird "smudgy" look to it.

You guys are awesome. I had been messing around with my in- camera noise reduction settings a few evenings ago and apparently left it on, for every photo, not on auto. Face palm to self. Thank you for the help.
