Used Tom For's ACR Calibration Script w/ my EOS-20D

[danaltick]

I've never created an input profile for my Canon EOS-20D because it just seemed like too much trouble to do.  But after discovering the ACR Calibration Script, I decided to give that a try to see if would make a difference with my RAW images.  I took a well lit shot of my MacBeth card in outdoor overcast lighting and ran the script on it.  It took almost an hour to complete, but the results were awesome.  The greens are greener and the other colors match beautifully.  So now I have two separate ACR settings, EOS-20D No Auto and EOS-20D Full Auto.  I'm using the EOS-20D Full Auto as my Camera RAW defaults.  Just thought I would pass this along.  It's definitely worth using.  Thanks Peter for posting a link to it at your site.

Best Regards,

Dan,

If you do a lot of indoor flash photography, it probably makes sense to take a shot of the MacBeth card with a flash and run the calibration on it as well. I have a 20D and 580EX and have always had problems with reds. I just ran it last night and have only played with the result a bit. Just like the outdoor calibration, it is much less flat (color-wise) than the preset, though to be honest, I haven't tested it enough to decide whether it is materially better for flash shots than the original calibration.

Hi Steve,

Thannks for letting me know about this.  I do actually do macro photography and use a Canon MT-24EX twin-lite flash.  I will take your advice and do a flash shot of the card as well.

Dan,

I played around with both calibration sets this afternoon, using some indoor flash shots for an informal test. I notice a slight difference (primarily in the reds), similar to if the WB was adjusted from one version to the next. I'll probably use one or the other depending on the image; nice to have an easily accessible choice. Oh yeah, 50-60 minutes sounds about right for the calibration, imagine how long it would take if you were crazy enough to go for that level of precision manually.

P.S. Off to download your Genie backup software and give it a spin.

Thanks for the info and good luck with GBM.  I plan to do a flash calibration as well when I get the chance.

I suggest that you save the calibration as a Camera Raw subset.  That way you can apply it from Bridge (or Camera Raw) independent of other settings you might use on the file.

[danaltick]

Yes, most definitely.  Thanks for letting me know.

Peter,

I also followed your advice in the book and went ahead and added strong curve contrast with the Camera Raw Defaults setting and removed that from the Full Auto and No Auto subset for my camera.

I must say, these RAW proofs are really starting to look good now .  I'm really anxious to get started with the migration.

Wait a few days for RapidFixer.  You may think it is a good addition to the workflow.
