I was interested to read on your website that Epson Scanners work best at multiples of 360dpi.
So in a way, 8x10 sounds like the ideal way to get maximum detail into film-based images for scanning, at least for those of us who are not blessed with drum scanners! (And yes, I'm very much aware that the consensus is that above 2400dpi, I will likely be hard-pushed to spot any real life gains at all - while resource-hogging will be very real.)įrom what I've learned during this little exercise, I assume that 8x10 users who scan on Epson flat beds would likely max-out at 2400 dpi for single image scan file sizes? Of course you'd very much benefit from the higher film resolution and less grain using only half the enlargement. With that knowledge: If I set custom resolution on Vuescan to 4800dpi, I do get 4800dpi scanned files which open fine, and are around 2GB.Īt these levels, of course I see some grain in shadows long before I see pixels, and it does all become a pixel-peeping exercise at enormous enlargements to spot any differences at all - so I think I'll settle for that and do some processing to see if I can notice any difference at all further down the editing line between 2400, 32dpi scans. which of course is the file size limit for TIFF files! So at 6400dpi, it would be four times that file size, either just above or just below 4GB. Having thought about this all, looking at those numbers, this is all likely based on a bit of a school-boy error on my end though:Īn uncompressed 48bit RGB TIFF at 3200dpi 4x5 gives me file sizes of 1.2GB, a TIFF using compression is just under 1GB.
Vuescan cost software#
Epson scan software doesn't let me select 6400 dpi (well, it does, but then says 'file size too large' and doesn't start the scan.) It does let me select and scan at 4800 dpi, but then it produces a file which Photoshop can't open ('unexpected end-of-file'.) Some people might suggest going to a Mac, and I do have that option, but it would simplify things greatly for me if I could get this to work on Windows. So if you have encountered the same problem and managed to solve it, or even if you have just from the beginning been happily achieving 6400dpi at 4x5, it would be great to know your settings! I would be keen though to scan at the highest optical resolution possible (6400) and then to reduce file size in PS - even if just to compare the results. I do realise that many people suggest that scanning above 3200dpi with the Epson flatbeds won't give you additional image quality, and I do respect that oppinion. I have increased the 'image memory' size setting in prefs, to more than 9GB, which should be plenty I believe, but without success. I found a 5 year old thread to this topic here on the forum, but without any clear-cut solution at the time other than scanning parts of the image separately and then stitching them together - which I would be keen to avoid. I do get 6400 dpi files from 6x7 medium format without problem.
Vuescan cost 64 Bit#
I'm using an Epson V800, latest Vuescan version (on a Win 10 Pro 64 bit PC with 16GB RAM) - and have no problem choosing the 6400 resolution in the interface, but the image files produced are only 3200 dpi. Are there any forum users which use Vuescan on a PC to scan 4x5 negatives at 6400dpi on an Epson flatbed?
