Hi all,
Well, I got my 'new' HP5370c scanner c/w Transparency/Negative adapter and masks. The flatbed seems fine. I scanned a few bar codes, which are probably as good as anything for checking the focus, and they seem nice and crisp. But when I tried slides, with the resolution screwed up to max (only 1270, but I thought that would be good enough for what I want to do), they are all fuzzy. Haven't looked at them for a long time, but I don't remember them being out of focus - and certainly not all of them.
Any advice for using these adapters?
Regards - John
ps "Work Bench" doesn't say "Camera Work Bench" !

John, are your slides mounted? Some of mine are mounted so my flatbed doesn't focus on them well which I'm sure it's because of the space between the emulsion and the surface of the glass. This is why I resorted to the technique Peter posted a while back. (actually, a variation of it) www.geocities.com/stevegrob/copy.htmlI have an Epson 2400 with a TPU but the masks for it are not ideal, so I never use them. The problem is that they don't hold the neg/pos flat against the glass. I went down to the Dollar Store, bought a picture frame and took the piece of glass out of it. I use the piece of glass to hold the transparency flat on the glass. Also, Rick posted some good pointers on scanning: See "It's spring here" located in the Sights of the Season folder. Steve

Thanks Steve,
I thought it had to be something to do with the distance from the receptors. Actually the slides are mounted in thin card rather than plastic frames, so it may not be too bad. Will try putting them directly on the glass instead of using the supplied mounting masks (which raise the distance even further). If that improves it, will try negatives directly on the glass. You'd think the hardware would adjust the receptor height when using the adapter and mask.
Or maybe it's supposed to, but isn't, and thats why I got the scanner so cheap !!
Regards - John

John,
Watch out for Newton's rings if you put the transparencies or negs straight on to the glass. I thought all scanning lenses had a reasonable depth of field. Also, make sure you have the slides the right way up. An easy mistake to make, and I've done it more than once.
Peter
