I am curious about the Camera RAW Graphic User Interface displaying white point "Color Temperature". Higher color temperatures yield a "warmer"(redish) looking white point in the UI. This is false. Higher color temperatures in Kelvin yield a "cooler" (blueish)looking white point not a "warmer"(redish)looking white point. This is confusing for those who calibrate and profile their monitors to standards like D50 and D65.

The Color Temp slider is indicating what white balance the shot was taken under. . .not the correction being applied. So, you are thinking about it backwards.

I'm in need of a work flow to set some personal white balance files for my 1ds
after shooting a macbeth target what would i do next.....because when i try to open a raw file and put it back on the micro drive the camera cannot read the file

thanks barry

I don't believe that it is possible to do what you are proposing. The output from ACR isn't a Canon raw image and is therefore unreadable by the camera.

I would add that I think that creating WB presets kinda defeats the pupose of ACR. Given that ACR allows you to WB images VERY accurately a time of conversion you shouldn't really not get too worried about presets. Typically I would capture one image with the Gretag chart included and process it in ACR then batch process all other images taken under the same conditions using the Droplet technique discussed by Russell Brown at:

BTW: use the second white square for WB rather than mid grey as demonstrated in the video.
