That's certainly the basis behind Picture Styles, ALO, etc. But, are you suggesting that if I use the same NR settings in DPP with different cameras, I will get different amounts of NR? Certainly, the defaults vary by camera. So, for example, the defaults for ISO 3200 are:
- 5DII - luminance 6, chrominance 6
- 7D - luminance 5, chrominance 12
- S95 - luminance 15, chrominance 16
- S100 - luminance 17, chrominance 17
Say I set DPP to luminance 8, chrominance 8 for all for cameras, are you suggesting those same numerical settings would be applied differently to the different images, based on the sensor/body? I'm not sure that this is the case (but knowing Canon, I wouldn't be surpirsed in the least).
Hey, thanks for writing back. :-) I'm always happy to see someone else do a review as well. :-)
fyi, looks like in the link I posted earlier for low light -http://forums.dpreview.com/forums/readflat.asp?forum=1010&thread=39700614
And for a listing of all my s95 vs s100 comparison threads -http://photography-on-the.net/forum/showthread.php?t=1110007
I had thought the "View Original" link was turned on, it's turned on now.
Back to noise reduction, there are 2 separate things that I'm saying -
1. As you noted, different cameras have different defaults. For example, from the s90 to the s95, at iso80, detail noise reduction was by default set to "0" on the s90, but on the s95 it's set to "2" (in my opinion sensor noise was the same but with 0 blue skies were often slightly noisy, with 2 they were clear).
2. However, on an entirely different note, the actual noise reduction algorithm used by dpp is entirely and completely different
based on whether the raw file was shot with an s95 or an s100. If you are used to how the s95 shots looked, and take high iso pics of people indoors, the differences are very
I imagine Canon came up with new noise reduction with it's new processor, and wanted files converted with dpp to look about the same as in-camera jpg's, so they apply the new noise reduction to s100 files and the old noise reduction to s95 files. The s100 noise reduction nearly completely eliminates noise, but can sometimes give peoples faces a plasticy, or "to much makeup" look. The s95 pics never have this look. (On the other hand on other photos the s100's noise reduction manages to eliminate noise without giving people or objects this look, so sometimes it's an improvement and sometimes it's worse). It doesn't matter whether you shoot raw or jpg (for my comparisons I shot RAW+JPG so I would have both) - dpp converts them differently. And you know it's the noise reduction because if you turn off the noise reduction in dpp the s100 files no longer have that different look, they look fairly similar to the s95 files.
