multi sampling NUDGE option on Epson 4990
PostPosted: Thu Aug 03, 2006 8:48 am
Hi to all at the forum.
I have an Epson 4990 and scan large format transparancies at a resolution of 2400dpi in 16bit mode. The scan size is 498MB. despite having 4gb of ram, a 2.4ghz dual core processor, a 250gb hard disk and setting up a separate hard disk partition for Silverfasts Scratch Disk for multiple samples, & increasing virtual memory to its maximum in Windows. If I multi sample 8 times or more the resulting scan is blurred as the system is struggling to compute the large amount of data. Reducing the scan resolution to 1800dpi or less cures this problem.
It would be nice to have a manual alignment option either in Silverfast or HDR where the resulting multiple scans can be nudged/aligned by hand using the arrow keys.
I can see this being a completely separate software application, but wondered if anyone else had encountered this issue
