I recently picked up the Color Checker Passport in the hopes of improving overall color presentation in my images. I'd be very interested in hearing from those of you who are using this product to hear how you get the best results.
I'm using Lightroom 3 and the CCP allows you to create camera calibration profiles, which can then be applied to images. Is it best to create a new profile for each and every shoot? Or is it only necessary for each body, or body/lens combination? If it's necessary for every shoot, it seems like managing the list of profiles is going to become a pain pretty quickly.
On a more fundamental level, what is the difference between how the profile operates and setting the white balance correctly impacts images. Aren't both mean to create accurate colors?
