Camera (Input) Profiles

Hi there,

Can someone advise which 'camera profile' is best for starting all enhancements? This is obviously crucial, as the colour values of the preview will determine the amount of adjustments made!!

I am shooting on a 1DS MKII, in the 'Adobe RGB 1998' colourspace ( images begin with an _ ), however in C1 v4, there is no 'Adobe RGB 1998' camera profile to select!!! I can only select the generic 1DS MKII profile, which is considerably brighter and more saturated than the 'Adobe RGB 1998' profile, which was available in v3.7. Under the Adobe list, I can select 'DNG neutral', which is less saturated! Would this profile be more accurate to start making adjustments? Or am I stressing way too much about this?

Thanks

  hello,
  
  The 1DS Mark II profile is going to be your most accurate starting point because it is created with the camera in a scientific environment to describe the cameras response. Adobe RGB is a generic color space that has no relation to the characteristics of the camera. When you set the color space in the camera it really only applies to shooting tiffs and jpegs. All that being said, if you prefer the colors from a different input profile, by all means go for it because color after all is subjective. 😄

  Did you set AdobeRGB as camera profile in C1 V3x?? It's the wrong way.
  In V3 you set the camera profile and the working space (AdobeRGB) in the same tab:
  In V4 you set the camera profile in the quick tab and the working space (output) in the batch tab:
  If you set AdobeRGB as camera profile, AdobeRGB is assigned as input profile. Result: wrong colours and much too dark.
  Why?
  Colours: the AdobeRGB profile does not represent the colours captured by your camera.
  "Brightness": AdobeRGB has Gamma 2.2 the phase camera profiles all have Gamma 1.8. So if you assign AdobeRGB intstead of the camera profile as input, the image is getting darker.
  They right way is setting the right input profile (canon 1ds mkII generic) and to convert the image in your working space. If you set cm-setting as shown above everything should be fine.
