Dang Adobe's hide and the Photoshop limits on Tiff file sizes!!!!
OK, I will admit this is not a typical snapshot, but I was editing along and saving successfully. I then did something Photoshop decided it did not like, and all of the the sudden it decides the file is too big.
Of course I had some really good edits and it was a over an hour before I had last saved. Evidently I was skating along at just under the 4.0 GB tiif file limit for Photoshop. Something pushed it over the limit, and no more saving. Argghh
So I jump through a bunch of hoops to save it as a PSB which is only a Photoshop format, cut it into two pieces as tif files, drop my edits on top of the halves, save those, go back to my mapping program and bring in the halves, and make a Tiff file with no problem. Then open that is Photoshop and I will be damned, Photoshop is happy again and it opens and saves as before. There were no layers, channels, paths. Arghhhh. Why Adobe why?
The good news is I managed to endeavored to persevere!
