Noise reduction: in camera or on post-processing?

I'm planning to shoot in a low ambient light and thinking of increasing the ISO to 800-1600.

In order to get the optimum noise reduction, which one is the best practices?
- apply noise reduction in camera only.
- apply noise reduction on post-processing (in-camera noise reduction is turned off)
- both (in-camera noise reduction + post-processing noise reduction).


thanks.

If you do it in camera, then the camera will be making the choice for you (and maybe not the choice you would like made). Post process lets you analyze which noise reduction (luminance, etc.) to use and how much without risking softening the picture before you see it for aftershoot work.

I gues it's a matter of available time.

How much energy do you want to put into postprocessing your photos?
1. If you are going to work on all of them -> shoot raw, turn off jpeg.
2. If you want to store / print them right out of the cam, turn off RAW, experiment with the camera settings to your liking (sharpness, colour, noise reduction) and leave the settings alone thereafter.
3. Are you somewhere inbetween; use the last approach and press the RAW button for the ones you think you really want to do PP on and get yourself a proper piece of software.

Success,

- Bert

PP for example can allow you (if you are willing to spend your time) to apply different noise reduction techniques/parameters/etc to different parts of the image based on what you want to achieve.

thanks for all the replies.

I had several shots using high ISO (1600) and after looking at the results (just raw conversion via Bibble without any noise reduction) ,
I was surprised with the noise and made me thinking,
is this still acceptable, OR
is there anything that needs to be done to improve the IQ

In camera noise reduction will lose detail in the image, and it cannot be brought back. Noise reduction blurs the image so that the noisy pixels are smoothed out. If you leave it until post processing, you have all the image details, and you can decide how much of the detail to drop out to smooth the noise.

Shoot raw, post process noise reduction, gives you max control of the finished result.

i say try them all out and see for yourself and decide what YOU want.

but if you want the cleanest output with lots of detail, you should shoot in RAW and do your own noise-reduction in post-processing.

i am personally very happy with the noise/grain of the lowest NR setting for jpegs in the K20D in high ISOs for personal shooting.

also make sure you expose to the right. underexposure at high ISO results in nasty noise.

While I sometimes enjoy the photo-like 'grain' of the 20D's output, I would recommend RAW and photoshop.

On my K10D I have in-body NR turned off, shoot RAW and post process in LightRoom with custom levels (usually not a very high setting).
