How to set Red and Blue Color Adjustment in RAW Format Preferences in 1.8.6 ?

[pdarmody]

Hi,

I just upgraded to 1.8.6 and would like to re-establish my Red and Blue Color Adjustment settings for the RAW format.  How do I do this in 1.8.6 ?  The dialog box in my earlier version of PI looked like the attached screenshot.  I had two sets of red/blue adjustments:  one set for each filter that I used with my Canon T2i.  This screenshot is from my OneNote notebook, so all of the text you see is notes to myself to help me remember all of this stuff.

I don't see the Red and Blue Color Adjustment fields in the new RAW Format Preferences dialog box.

Thanks,

Pat

Hi Pat,

I removed these color balancing parameters from the new RAW tool in PixInsight 1.8.6. Applying multipliers to raw CFA data is unnecessary because you can—and should—use the PhotometricColorCalibration tool to achieve consistent colors in your integrated linear image. You can use also the PixelMath tool to multiply the channels of your image by arbitrary constants, if this is what you really want. Finally, if you work with an unmodified camera, where default camera white balance factors are meaningful, you can enable the 'camera white balance' option in RAW Preferences.

Hi Juan,

Thanks for the reply.  I use a full-spectrum modified Canon T2i when shooting DSLR. So, I don't use the "camera white balance" option in PI (I even made a note to myself not to do that.  I had tried it once and the results were not good.)  Nowadays I always shoot with the IDAS LPS-D1 filter to keep UV/IR and light pollution in check.

I have always used ColorCalibration, but was not aware of PhotometricColorCalibration.   My PI workflows have always been pretty simple, but have gotten the job done. 
Still, I am happy to learn new things.  Is there a good tutorial or posting on PhotoMetricColorCalibration that you could recommend?  Same question regarding tutorials/postings on PixelMath for color balancing.   (I have never tried PixelMath either.  I know that I am a very basic user...)
