But if the rules were such as:
1) all RAW adjustments set to neutral (no noise reduction or sharpening either)
2) white balance as measured by the camera
3) straight conversion to sRGB without any tweaking
4) high quality JPEG or PNG web output, ca. 600x600 pixels
5) 100% crop of one to three representative details as selected by the photographer
Then I guess we could see something. I'm not sure what, though.
And I may have forgotten something here.
