Morning all.
I installed the latest version of Photoshop CC on the big boy computer. I was really hopeful that it could open the huge tiff file but 36 gig tiff files are way to big for Photoshop. I did export a 20 gig part of the image and I could open it in Photoshop but it will not write a tiff file that big.
If can open the file, and then just try to save as, and it will not write any file except the .psb format which none of the mapping programs can use.
From the reading is looks like the little bitty 4 gig tiff files are as big as it can handle.
