p.1 #1 · Canon 5D and red colors.

Hi everyone,
I have found that the 5D and I think digital in general do not like the color red. I recently had a fashion shoot and the model wore a brilliant red gown. I shoot raw and I tried to process the photos first in CS3 and the red was washed out. I have the latest Camera Raw 4.5 (beta). I also tried my old faithful Capture one, close but no cigar. I finally tried the conversion in my version 1.42 of Breeze Browser and then I got the correct red.

What have you found when you process brilliant reds. Can you suggest any other program.

Digital sensors are very sensitive to bright reds (and yellows) - they very often blow out.

Check out the new ACR 4.5 and the revised camera profiles from Adobe. They were intended to fix reds on Canon bodies, among other things. I haven't yet tried them - still waiting for my boxed copy of Lightroom 2 final.

In ACR 4.5 you must download the new beta camera profiles from Adobe (new last week).

Selecting the beta standard works much better for me.

Also try Canon's own DPP with the 'Faithful' rendering. I read somewhere that Canon's sensors do not have very strong colour filters over the RGB sensor sites - this is to maximise light transmission but is at the expense of colour fidelity - could be BS as it was from a MF digital company man.

WOW - I've just downloaded the ACR beta camera profiles - at last they have got their act together and we now have the possibility of descent colour output!

I am curious as to what raw conversion program BreezeBrowser is using. I know chris did not code it himself?

Gotta add another wow for the camera profiles located at http://labs.adobe.com/wiki/index.php/DNG_Profiles - the color rendering is now dead on to what DPP will do... with really minor differences. This is for my 1dsmark2 by the way.
This is definitely a step up for ACR and no doubt a reverse engineer coup for the ACR programmers!

Well Phil,I think this is really something you should try out for yourself...
I happen to use DPP for 98% of what I process, with the remaining 2% alloted to those files that are just a little bit more tricky to deal with... and it's a bonus to have the extra flexability of ACR with the color rendering of DPP... so that is why I happen to find it amazing. Try it yourself, and let yourself be the judge

All they need to do now is fix the crude demosaicing algorithm and ACR with be the king of RAW processors

What's so crude about it? Other than the fact that it isn't omniscient, that is.

It's got bad anti aliasing on detail with diagonal lines - well DPP is the same, C1 seems to do it better.
