    Camera Raw Profiles for Canon

    benjaminvingrief Level 1

      Hello,

       

      My post is to show that i think there is something wrong with the profiles created by Adobe for some camera (5DS / 5DSR / 5DMarkIV), and i will try to explain why here. It's a serious post, and not a whining post etc.

       

      I do a lot of retouching for many camera , and i'm stuck with the raw for 5DS/5DSR/5DMarkIV and not with some others (5DMark II/5DMarkIII/6D for example). No problem with Nikon/Sony at the moment.

       

      My problem is about tonal response curve included in the dcp profiles. The dcp profiles for 5DS / 5DSR / 5DMark IV are made with an "adobe98-look" tone curve. Resulting in crushed blacks, and to much contrast.

       

      Just to prevent some answers : it's not a calibration problem. I'm fine with all RAW for many camera, except 5DS / 5DSR / 5DMark IV, and i tested on many computers, mac and windows. And with different calibrated monitors etc.

       

      How to see the problem :

       

      5DMarkIII :

      When I open the raw in DPP (canon), the raw have a srgb look (srgb / srgb).

      When I switch to adobe98 (srgb / adobe RGB), the tonal look is "crushed" in black and contrasty.

      When I open this raw in Camera Raw with the "Camera Standard", the tonal look seems to be in srgb, like in DPP. It's fine so

       

      6D :

      When I open the raw in DPP (canon), the raw have a srgb look (srgb / srgb).

      When I switch to adobe98 (srgb / adobe RGB), the tonal look is "crushed" in black and contrasty.

      When I open this raw in Camera Raw with the "Camera Standard", the tonal look seems to be in srgb, like in DPP. It's fine so

       

      5DS / 5DSR :

      When I open the raw in DPP (canon), the raw have a srgb look (srgb / srgb).

      When I switch to adobe98 (srgb / adobe RGB), the tonal look is "crushed" in black and contrasty.

      When I open this raw in Camera Raw with the "Camera Standard", the tonal look seems to be in adobeRGB, NOT like in DPP. It's NOT fine so

       

      5D Mark IV :

      When I open the raw in DPP (canon), the raw have a srgb look (srgb / srgb).

      When I switch to adobe98 (srgb / adobe RGB), the tonal look is "crushed" in black and contrasty.

      When I open this raw in Camera Raw with the "Camera Standard", the tonal look seems to be in >> adobeRGB <<, NOT like in DPP. It's NOT fine so

       

       

      To summarize :

       

      For some canon camera, you have edited your dcp profile to match dpp very well (6D / 5D Mark II / 5D Mark III), but for 5DS / 5DSR / 5DMark IV, the match isn't fine, because it is matching an "adobe98" tonal curve, and not a "srgb" tonal curve.

       

      Is it possible that Adobe, makes "srgb look" dcp profile and not "adobe98 look" dcp profile ?

       

      Thanks.
