Re: neg scanning

I'm thinking of keeping the Jessops 8ookb for my neg bakups for those
negs that are not ever going to be blown up above 6*4. For the others I'm
not sure quite what to do. Many of my negs are now battered and scratched
and I noticed that an 800kb scan at the shop removes the scratches,
whereas my scan would take a very long time to scan and remove scratches
at the same time. I don't have the time to scan at very high resolution
and use ICE. My other concern relates to wether the higher resolution is
going to make a noticable difference for a A4 size print. My friends
compact camera produces jpeg images of about 4-5MB, his Nikon F70 of about
2MB. When he prints images from the diffreent cameras at A4 size the Nikon
wins, always. As I said, any comments appreciated, before I start
scanning. There are about 1000 scans to do!

Hi.

You seem to be giving some mixed information here.

When you speak of file sizes do you mean a Jpeg which has been compressed
and the size is being read off the Icon, after the image has been closed.

I suspect so, because a Nikon D70 will produce an image size of about 18Mb.

6Mp sensor working in 3 colours, 6x3 = 18mb

If Jpeg compression is applied the file size on disc (closed) could be 2Mb,
( or less), but when opened for printing or editing, in a program it will be
18Mb.

There is no way anyone can give you advice based on the closed file sizes of
compressed Jpegs.

Not only that but the Compression process will discard information, and the
quality will suffer.

When an image is open for printing, you need a resolution of 300 Pixels per
Inch for a good quality print. For a 6 x 4 that means 6x300x4x300 Pixels (
2.1Mb).

As I said earlier a Minolta 5400 is capable of producing a 230Mb scan from a
35mm frame. It can do so in 45 secs without the use of ICE or Grain
Dissolver. This time does not include Preview Scans or time for Adjustments.
Using a lower resolution scan will not really save any of that time.
