AuthorSubject: Camera profiles via the Digital Dog method   [Go to Bottom of Page]
Allen Pacheco
Posted on Mon Sep 15, 2003 7:27 PM


Some time ago, I came across Andrew's Digital Dog site to read the color management articles and one of them stuck with me. The one titled titled "Using Photoshop 6/7 to create custom camera profiles." At the time I was using Canon's D30 and after playing with the method a bit I abandoned it. My results were not worth writing home about. I noticed that the article showed up on this site as one of the first few selected.

Well, now I'm using the 10D so I got interested in pursuing this a bit again. I often use Capture One and I wanted to improve one of their generic profiles which seems to be color challenged as far as handling neutrals. They have a fondness for the color blue even where it ain't supposed to be. Shows up in prints in particular and why use a custom print profile if the camera profile is hell bent on messing things up? No, it's not the camera...it is really the profile.

Andrew's article demonstrates how to modify an existing RGB working space in Photoshop. As he mentions, "while it is not a substitute for a true, stand alone camera profile packages, this tutorial is helpful for those users who's camera may capture into an "established" Working Space (sRGB) but may need modifications to produce closer, more accurate color."

So, I experimented a bit and got something that at least is well behaved in that R=G=B when it is supposed to. There is some color modification but nothing really drastic.
The same post-processing adjustments I had to do before still hold true. I used a utility that is meant to handle display profiles, not camera's, but it opened the generic and sort of "reduced" the profile down to exactly the parameters that Andrew's method requires.


I'd like to know if there are any drawbacks to using this technique. I know it is not a real camera profile and I'm not arguing that it is a great replacement for one.
But for my usage it doesn't seem to demonstrate any problems with tonality, soft-proofing, and display/printing.
What can the potential pitfalls be?
