Is in-camera high-ISO noise reduction worthwhile?
Should this be done using image processing software like Photoshop or the built in function of the camera ?
It seems a program like Photoshop would use a much better algorithm than what would be available in the camera, or does the camera do something else before taking the image?
Isn't the logic here the same as the logic for digital zoom (usefull only when shooting in a compressed format, as the zoom is done before compressing)? Or is there something else?
