Can anyone help me understand what is going on? I'm a relatively new DSLR owner so I'm guessing it's something I'm doing wrong or I'm not understanding the way things work. I noticed that I got what I thought was a lot of noise at 400 ISO so I just stayed at the lower ISOs. I recently took pictures at a March of Dimes walk and it was a rainy, dreary day so went up to 200 ISO thinking I'd be okay. Some of my pictures have more noise than I would have expected. I've attached a cropped photo - I didn't feel comfortable posting people who haven't given their permission to be put out on the internet. You can see the noise in the the background. I shot in shutter priority since I didn't want to be caught with a slow shutter speed and end up with a lot of blurred pictures. Alot of the pictures weren't bad but some were. Is the noise more a result of inadequate light than the ISO which I though would correct that, but maybe I should have gone higher? Would the moisture in the air affect noise in photos? Any insight?
Thanks for any comments!!
