This is super-interesting info! I wasn't able to use the IR channel within PS as of now. Could you explain how exactly do you perform the threshold correction (the 1st step)? Also how do you import the RAW tiff from Vuescan into Photoshop (without deleting the alpha channel)? Do you go through CameraRAW without a problem? Thank you!
I don't use CameraRaw (what is it?). I just open raw vuescan tiff file in PS.
I'm not at home so this is from memory:
- when you have opened the raw tiff in PS, select alpha channel
- go to 'Image - Adjustment - Threshold'
- move the slider so that you only see emulsion defects (it helps if you first set the canvas magnification high enough that you can see emulsion defects and observe how the threshold is working on your IR channel)
