Basic question..(Very!) - from a guy that's been in and out of photography for about forty years, but still a novice with my p.c. and digital stuff, after about six months - self-teaching. I scan my 35mm negs at 4800dpi for inkjet prints (my max. size-A4) -and get nice results, ...but tho I have put a few digital images on Ebay, I have never uploaded from a neg. and need to know what is the optimum resolution to go for, to give a decent display pic. on the forum, (or anywhere!) -obviously the size of file I'm getting now would take forever to upload!, Thanks and regards, Dave
P.S. Although I've got reasonably profficient with the inkjets, they don't stand comparison with the products of my old Durst enlarger! - b+w that is ! ( colour always was a bit too much hassle in the wet smelly stuff, for me!! )

Make them 72 ppi resolution, then size 144 px wide it will come out 2". 300 about 4 "
Or just put in the width in inches you want.
Image -resize- pick using above- use bicubic sharper. Then sharpen. Save as JPEG.

Dave,
You and I are definitely on the same wavelength---your questions mirror my own,although as yet I don't have a scanner capable of dealing with negs.,my own thoughts have already touched on this sort of uncertainty.
I'll follow the advice you get with great interest.
BTW.are you involved in ship photography up in your part of the world, by any chance?

just convert the scanned image to ~800x600, and save as a jpg. You don't need to mess with dpi or width in inches or anything like that. A browser is only going to display it at 72dpi anyway, and the width in inches depends on the size of the viewer's monitor and their screen resolution.
Scan as normal at 4800 dpi, then reduce size by 50%, and reduce again by 50%, repeating until you get the long side around 800 pixels. That's probably going to take three times for 35mm negatives. That should make the file size as a jpg within the allowable range, and the final image will be large enough to see details, but not bigger than most people's screens.

if you have photoshop you can just use "save for web".

Thanks for the tips, gents, - I'm slowly getting there! .....and yes,-the carbon inks sound interesting ?

If you're using CS2 why not go Image, Image size... change the pixel dimensions to 600px on the long side, then OK, save as... and post?

Uh, I think the OP asked *what* resolution, not *how* to get that resolution.
For me, 700 pixels hits the spot for uploading to websites (flickr for me mostly).
I use Picasa 2.0 (free download from google) Export feature for most of my resizing.
However, I find that 80% of the time I need to run the resized picture through a mild Unsharp Mask to regain the sharpness lost during the resizing. For that I've been meaning to write a small script that will drive Imagemagick's convert program, but haven't get around to it, so I just opened them in Paint Shop Pro and apply the USM manually.

Or use Photoshop and when resizing - use "bicubic sharper" resample algorithm. It works for me fine. No additional USM needed.
