When to use noise reduction

Chuck289

I just got a D3100 and have been learning and practicing with it. I was wondering what the downsides are of using in-camera noise reduction and when should it not be used?

Levels of noise and in-camera noise reduction amounts are both very personal issues and vary from individual to individual. I prefer not to use in-camera noise reduction at all because it tends to be of less quality, and certainly less controllable, than software noise reduction algorithms running in a full computer.

I would only recommend using in-camera noise reduction for those situations where you need to deliver JPG images immediately following a shoot with no opportunity for post-processing. Only testing beforehand will give you feedback on what levels are acceptable but the more detail in the original scene the less you want in-camera noise reduction. (In-camera noise reduction tends to be less discriminate about image detail and tends to kill fine detail more than the best noise reduction software running on a computer.)

Thanks. I guess I'll play around with some images to get a better feel for it

The only time I use in camera noise reduction is for long exposures at high ISO. Typically 15 seconds or more. This tends to get me to a good starting point and I still have to use NR in Lightroom. Just remember that for most DSLRs when you use in camera NR your camera will be "tied up" for an equal amount of time to the exposure. For example if you take a 30 second exposure you camera will need 30 seconds to complete the NR.

Hope this helps.

Thats when I started wondering about noise reduction. I was taking some long exposures of the stars and I was playing with the NR. I'm not sure if I noticed much of a difference.
