Are they 35mm slides/negatives? If so then 800 dpi won't be enough resolution. You should scan at the maximum optical resolution that your scanner is capable of - what model do you own?

I couldn't find anything about this scanner via Google - just the 9900F model. How old is the 990F?

Hi, Its new bought it a few weeks ago, Jessops recommended it. Just scanned a few slides at the most resolution it would take and it took ages, but did print out better.

OK - you will definitely want to scan at the 3200 dpi optical resolution, even if it does take a long time smile.gif

Scanning resolution usually depends on the size of the image you want to print, and you would normally want to print at 240 - 300 DPI so for a 10 x 8 print you would need a scan of 2400 - 3000 PPI (or thereabouts) for a decent print. That said, I always scan at the higest possible resolution and maximum bit depth (16 bits if your scanner is capable of it).

Now consider how much you value your time.

Each time you need to do a scan it takes you the better part of ten minutes for low quality but you will never want to save them.

Scan at the highest quality because, you should Scan once, Burn to CD once.

Me? I am frustrated by anything slow, but more so by having to do the same job twice.

I agree with the scan once at a large files size, more specifically at the highest *true* optical resolution for your scanner (not interpolated or marketing hype numbers). With some scanners, even if you scan larger than you need and then reduce, there can be the added benefit of what appears to be a reduction in noise that occures during the size reduction process.
