Holy crap.
I finally figured out what was going on with my colour profiles.
Here's the story:
I use iPhoto 5 (waiting for iLife '07, Leopard, Photoshop CS3, New Macbook Pros to arrive and pounce on a new setup). I've been having a few colour profile issues.
Basically, what I have figured out is that iPhoto 5 does not embed colour profiles into the images. It tags the iamge as having been taken in RGB colour space, but does not actually embed the files on import with the ICC profile. I believe iPhoto 6 has the option. But here;s the kicker - when you use the built-in editor, it assigns the Generic RGB profile to the file. Which changes the viewed colours somewhat.
Anyway, this means that my entire history of photos I ahve taken to date have no colour profiles assigned to them. Which is not really a problem, becuase the fact is the files have not been 'damaged', just don't have the appropriate colour assigned to them for viewing. IT just annoys me, because I have created a workflow that involves me not having to reproduce too many files - i Like iPhoto for it's non-destructive ordering - and it means that, to date, I have been showing a lot of my photos to people with them looking a lot less than they could be.
But I ahve now learnt a lot more about colour profiles. And, I have now learnt that iPhoto 5 CAN embed the color profile, but I have to do a bit of hacking around in the .plist for iphoto5.
Any way, I'm happy this is the 100th post, so I can inform people who are as stupid as me to not use a proper editing program, and an old buggy one (I hear iPhoto 6 doesn't have these issues).
Time to share:
On left(top) is the picture as I shoot it with the built-in Camera RGB profile embedded (I think - this profile only appears when I have my 350D connected). On the right(bottom) is the version that has no profile embedded, and is utterly dependent on your Display profile (ie, how close it is to my camera RGB - if I understand it correctly - so if your display profile matches my camera profile, the colours will look the same, but for me these look quite different - right is a lot more subdued). Please let me know what you see.
so...anyone else actually pay attention to the colour profiles? This is all new to me - I just did a lot of experimenting and reading... please let me know if I have got this all wrong or not.
