AcrCalibrator version for CS4 ?

[gdh]

Will current version also work on CS4?

[steve sprengel]

The AcrCalibrator script is obsolete, having been superseded by the DNG Profile Editor from Adobe Labs:

The script may run in CS4/ACR5.x but it won't be programmed to work in anything but compatibility mode which doesn't reset the sliders to 0 and the curve to linear like it should, so it is better to use the DNG Profile Editor than to use the script.

Using the DNG Profile Editor, you can use two images of the color-checker taken in incandescent (3650K) and D65 (6500K) lighting to make a single camera profile that works with all lighting conditions.  If you are more picky, you can create a custom profile for your various lighting conditions.

If you don't have a ColorChecker or it is old, you might consider buying an XRite ColorChecker Passport which contains a mini colorchecker in it's own little protective case, and software that will also create custom camera profiles, where it does not have the restriction of 2650K and 6500K lighting dual profiles like Adobe's software does:

You can download the ColorChecker Passport software free of charge by registering on X-Rite site.

 

Here is the link for downloading the software.

Also, I have ColorChecker Classic and the software seems to work with the ColorChecker Classic.

 

I believe you can shoot the ColorChecker Classic or Passport first. Make a temporary profile from that first image using X-Rite software and then applying the color profile to all the pictures that follow in the same shoot assuming the same lighting.

 

This should avoid having to make the  two images of the color-checker taken in incandescent (3650K) and D65 (6500K) lighting.

 

I found this blog entry on the X-rite site very informative.

However, Steve is the authority on this subject.

 

Steve, I am very interested two here your thoughts on this. Also, is there another group that you are following on this subject?

 

Thanks.

Yes, I neglected to remember the free-ness of the CCPP software if you already have a CC.  It easy to use and works well.

Using a situation-specific profile is likely to give the best color, but it requires making a new profile for each situation where this can work well if you have a small number of lighting conditions you work with.  I have speicifc profiles for regular incandescent, reveal incandescent, cool-white fluorescent tubes, modern compact-fluorescent-light bulbs, sunlight summer, sunlight winter, sunlight before sunset, shade, cloudy, twilight, sodium vapor.  However, I also have an incandescent-cloudy dual profile and use that most of the time. 

I am not a member of other forums that are specific to this color-calibration methodology.  I occasionally see some players I recognize commenting on new camera ACR conversion issues on various places, but it's been since the 7D first came out so don't recall where, now.
