I think it depends on how poorly you make the original exposure.
I shoot RAW
without noise reduction at the lowest ISO that allows a proper exposure with the hold technique available--funny how well that gets drilled into a person after thirty years. I think Lightroom is fine for routine photographs, Photoshop is best for 'work for hire' and various other softwares have particular strengths that make them valuable from time to time in either venue.
I shoot fast with a great deal of spontaneity and any in camera processing impedes the effort; besides the computer is both faster and residence to much more powerful graphical routines. I chimp only the first few frames of a new situation, but I have twenty-five years of film shooting and processing experience---I usually know what I captured and when I'm done.
I don't know your source, I would probably suspect it's validity and I seldom need to refer back to anything I've read either during the shoot or the processing. One thing I don't do is create more work for myself by doubling any effort.
Of all the extras on the modern digital camera, I most frequently use ONLY the white balance (and I suspect that's unnecessary some of the time). WB is one of the two primary ingredients delivered to the RAW converter for it to make an RGB file--the other being the RAW data itself.
In short I don't let the camera make decisions or process beyond what is necessary to get it to my computer. Once it's on the computer I make as few changes/corrections as possible. I'm very old-school!
Originally posted by Kemal I've read to shut off in-camera noise reduction when shooting at high iso's. Has anyone shut it off for all kinds of shooting (100 iso) when knowing you will process the photo in raw mode? I see the options and default settings for sharpening and noise reduction in lightroom- would it be better to avoid doubling these efforts and just have lightroom do all the noise reduction and sharpening?
