ADOBE DNG PROFILER AND INFRARED

4 August, 2008 (08:02)

“Infrared-modified cameras and extreme lighting conditions can cause an image’s white balance to fall below Camera Raw and Lightroom’s temperature limit of 2000 K. This tutorial explains how to use the White Balance Calibration feature to bring the white balance values into the standard range for these special cases.”

Luke sent me this link to a DNG PROFILER from Adobe.

And yes, initial tests (5 minutes this morning) show that you can get corrected white balance from the infrared RAW shot with this utility.

I don’t want to have to repeat all the instructions in this post, but here’s the link to the beta version of the profiler which creates Recipes and eventually Camera Profiles that can be used in either Lightroom or Photoshop (given the correct versions of everything).

Here’s the link to Adobe Labs DNG Profiler that got me through the process.

Thanks - Luke. As mentioned, this is Beta, and I’ll post more about it as I go along. Although I did get it to work - please don’t ask me any questions about it yet - as I’m still working my way through the steps. The main point, is that Photoshop and Lightroom clip the color temp. at 2000, and the profiler gives you a way around this for infrared and I suppose other special color balance situations.

This just gives you some idea of what is possible with the DNG Profile Editor. Neither shot has been altered at all in PS or LR, other than that in the camera calibration, I chose the “Park Avenue Profile” in Lightroom.
