At the moment I am testing a Canon Mark V out and thats is very nice indeed, focusing issue is much better and colour is spot on. Having said all that if I had to buy my own kit tomorrow I would buy Canon, both cameras have there pros and cons.

The “Adobe Standard” and “Camera Standard” profiles provided by Adobe in the Calibration Panel of Lightroom have a huge impact on both the color rendering and overall contrast in your images. Adobe has tried to provide accurate profiles, but large differences in sensor color balance exist within the same camera model (i.e. your Rebel may be different than mine!).

If you “truly” are that concerned about color balance (as I am!) in your RAW images, I suggest purchasing an X-Rite Colorchecker Passport ($100) and profiling YOUR specific camera’s sensor! I did this for both my Canon Digital Rebel (300D model) and Canon 5D MKII bodies. Please also keep in mind that lenses (and even UV filter use) contribute to the overall color balance, with lenses from the same manufacture’s line having variations (i.e. a simple 50 macro may be different than a 70-200mm zoom). Lenses form 3rd party manufacturer like Sigma will have larger differences than your camera manufacture’s lenses.

NONE of this is complicated stuff, when you use the Colorchecker Passport to create custom camera profiles for each body and perhaps different lenses you use with them. One important step that X-Rite does not stress is the need to “White Balance” each profile as well. The camera profile does NOT contain “White Balance information, this must be done as a separate step. You can then save this as a “Devlop Preset” in Lightroom, by checking just “White Balance” and “Calibration” and then saving. “The Colorchecker Passport can also create “Dual-iluminant” profiles for Daylight + Tungsten balancing- WOW!

The results I have obtained with CC Passport completely blow away the Adobe Lightroom provided profiles, with better color rendering, saturation and contrast balance. NO, I do not work for X-Rite, but have been a serious photographer (and engineer) for 40 years!
