It's funny, with a title like "Corruption" you'd think I'd be talking about the philosophical corruption of the soul or how the industry is corrupt or we're corrupting young girls by feeding them eating disorders.
This is a followup to Corruption.
Opened up one of my full TIFFs with layers yesterday and found this:
It's supposed to look like this:
As usual the layers in this file are flattened (though they were not flattened when saved).
Oh and my flattened version of this file (also a TIFF) is also corrupted. It has nothing to do with the layers.
I haven't had this kind of file corruption since the original post. I previously suspected bad sectors on my SSD. Now I believe I have a better idea of what's going on.
In each incidence of this type of file corruption, I had several open PS files. In each case I discovered this problem after moving from either my home office to the studio or vice versa. Photoshop is either not happy with sleeping on open files OR it's not happy with attaching different displays when there are open files. The odd color shifting seems like it might have something to do with color profile attachments. But it could be something else entirely.
The irony is I just recently stopped saving duplicates of the TIFFs (full-layered and flattened) to save time. But now I suspect that the duplicates would also be corrupted because I believe the corruption happens during the save. The strange thing is that immediately after saving the TIFF to Lr and exporting a web-sized JPEG to the desktop, the export file is intact revealing no cause for alarm. But now when I examine the same file in Lr, it reveals that it's corrupted. Exporting this file also reveals a corrupted export. Not sure why that is.
Without doing extensive tests on the situational variables involved, I don't think I'll be able to figure out exactly what causes the corruption. But I suspect there's something going on with Photoshop and its ability to render files correctly either after sleep/hibernating and/or when connecting different displays while files are open.
