Canon image quality/rendering
You can get them to look close, but there are small things that don't match up, Canon has very different kind of noise from Nikon for example, I find Canon noise pleasant whereas Nikon noise leaves me cold. Probably not a big deal (or even noteworthy) from some, just something I pay attention to in addition to all the other things.
I shoot RAW and PP noise reduction with Photoshop CC, Topaz DeNoise, and Nik's Define...so noise quality is basically the same regardless of brand or model...in the final product. For someone who uses predominately in-camera PP (JPEG) or little PP NR... I can see what your saying, but more model than brand differences when shooting RAW
My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
