This is driving me nuts and I cannot seem to find anything regarding it. I'd use TWAIN happily, but my scanner doesn't seem to have a 64-bit twain driver. So I'm stuck with WIA. But, the thing that drives me crazy is that WIA always creates the file with an arbitrary name and format which I always end up having to delete later. I much preferred the old TWAIN method that just scanned it directly to Photoshop without any file made until you saved it from Photoshop. So, this may actually be more of a Windows M$ question than Photoshop, but I'm giving it a shot here.
Is there anyway to scan directly into Photoshop CS4 64-bit without WIA creating a file at all?
There are no 64 bit TWAIN drivers on Windows.
I think the WIA interface from Microsoft always creates an intermediary file.
Give Vuescan a try. It supports direct scanning into 64 bit Photoshop. www.hamrick.com
