General / Making masks with photoshop then importing into photoscan

« on: April 09, 2015, 07:42:18 PM »

I am using a green screen to take JPG images with a fixed camera and a turntable.  For whatever reason I can't get photoscan to use a standard JPG photo as a mask with good results.  So, I turned to Photoshop where I can create a macro that quickly masks out the background and creates an alpha channel.  The problem is this... I'm not sure what is the best way to incorporate the photoshop mask.  I can't embed it in the jpg without altering the exif data, right?  I also don't want photoshop to re compress my JPG introducing more artifact.  I could use the RAW data but that would be new to me, and I still don't know what format Photoscan would want the file in.  I tried importing the PSD file but PhotoScan didn't want to do that. 

So, the question is, what works and what works well?

I know this is a simple question, but I couldn't find anything in the manual about good ways to do this and I couldn't find anything by searching.

Thanks a lot.
