Hi,
My dad has finally got around to buying a decent enough slide scanner to digitise his 10 thousand slides <- long job.
He got an Epson V700 flat bed.
He read somewhere that he should scan at 3600dpi, but when he does, each image TIFF is like.. 1 GB..
At 2400dpi the tiffs are 450MB, even at 800dpi they are 40MB which seems pretty big.
hes barely computer literate by the way..
I suggested to him; he might want to keep a small ish jpeg and a TIFF for each image. jpeg for general viewing and sharing and the tiff for projecting or printing. Really he wants to chuck his slides once hes scanned them all so needs to find a decent method and stick with it.
Having played around we can barely tell the difference between a 4MB jpeg and a 450MB tiff. It seems to come down to the quality of the slide, and when zooming in the image gets blury way before the pixels are visible. perhaps on sharper more recent slides this might be different but even so.. the jpeg from an 800dpi scan zoomed in could almost fill the wall before you could distinguish it from a high dpi tiff.
Does he really need to be forking out for umpteen 1 terabyte hard drives to save massive files? Or can he make do with small jpegs? Does he really need to scan at large resolutions? Or will 800dpi do?
any advice from *** with more experience would be great, including your own prefered methods
thanks in advance! -sorry for long post
