| p.3 #4 · High ISO still life 5D3 vs. 1DX |
FYI, Adobe ACR appears to be adjusting the exposure of 5D3 images up by about 1/3 stop when I compare the 1DX vs 5DM3 raws, when both are using the Adobe Standard profile. I've seen this same behavior on the D3s vs the D800. So to produce comparable images the raws need to be processed using ACR's Camera Neutral profile (which mimics Canon's Neutral DPP profile). Without this normalization the 1DX will have an unfair advantage over the 5D3 when comparing the images side-by-side.
It's quite interesting how different ACR is rendering the files from the two cameras when using certain Adobe cloned Canon profiles. 'Camera Standard' for instance causes the 5D3 file to be more saturated and applies a contrastier tone curve.
I took a look at all the images in DPP and the color, contrast, and exposure rendering was near identical, as you would expect.
However, I *stongly* dislike Canon's new default sharpening approach, which creates visible halos and edge artifacts and generally makes the images look really artificial.
So if using DPP to evaluate images, you may want to switch everything back to the legacy sharpening algorithm. (Unfortunately, there is no way to make this an application default.)
That must have been what I was noticing re tonality, wish I had the curve expertise to neutralise the difference.
