I've found out that some of photos take with my 5D MkII have more shadow noise than I like. I know there are some obvious settings that affect this, such as ISO a noise reduction settings. But there are some other image processing functions that probably raise noisiness of the images.
This was shot at ISO 400, and kind of underexposed. Other settings I believe might be relevant:
- High ISO NR: low
- Highlight tone priority: disabled
- Auto ligting optimizer: low
- Peripheral illumination correction: enabled
Now, is there some kind of tuning of all this I could do to achieve pictures with which I can postprocess a bit without getting noisy results, or should I consider this normal and focus on taking pictures rather than thinking about chroma noise?
