Photoshop with large files
My wife and I had been hunting down a wedding photo of my parents and finally got one yesterday (thanks Grandma!). I quickly scanned it at her house at 2400dpi into TIFF to make sure I had everything possible for correcting it and enlarging the 5x5" print to 11x24". Luckily, I had my laptop to transfer the 300MB file.
As one would expect, the photo is riddled with color decay, red spots across a large section, and dust and scratches all over it. I've been editing all morning with nine layers adjusting colors and such. Suddenly, Photoshop gives me a warning about being unable to save past the 2GB boundary. Never fear though, switch to Adobe's "Large Document Format" (aka PSB) and keep working. Unfortunately, PDB is likely to be less compatible with non-Adobe products though.
Hope this helps...
