when I im[port images from my converted camera everything is ok until previews are built ...my images take on a magenta cast (something I corrected for by using a custom white balance in camera)..help..please
You can use the Adobe DNG Editor to create a variation of your Adobe Standard profile that has a WB adjustment to better convert your IR images. Look at the information, here:
The issue is that the WB in LR and ACR has a minimum of 2000K which is now low enough to match the IR color temperature so adjusting the WB negative in a profile allows the effective WB to be lower than 2000K.
thanks I will try that latr meanwhile I'm just usung a infrared filter in lightroom..again it's just in the preview
