All I meant was that the effective resolution increase available from the Polaroid was not terribly significant; just barely there. Remember that the dpi ratings of scanners are not really true resolution numbers, it only tells you what size file you can create. Just like with conventional film when taking pictures; if you use Tech-Pan, and it can resolve 400lp/mm (I just made that up; I don't care what the exact figure is) then your negs will not have a resolution of 400lp/mm. There are a _whole_ bunch of other factors at work, all of which degrade the final result to some extent. >Velvia can be tough to scan if you have a really dense piece of film. >Maybe thats why I use negative film a lot. Negative film is definitely easier on a scanner, especially CCD scanners. An LS-30 does a very good job with negatives for example, but is marginal even for transparency films with low Dmax. I still have a lot of Kodachrome to scan, and even the newer 100ISO films will have shadow detail that gets ignored by all present CCD scanners, even ones like Imacon Flextights. I just want to get everything out of the film that my budget allows, and extra shadow detail is more important to me than the small amount of increased resolution that I was able to achieve with the Polaroid. Plus the batch mode thing with the Nikon, which is a huge timesaver for me. >Glad to hear that your Nikon works so well for you.

They've had some 1600's in, but not the firewire model. Maybe soon... * Henning J. Wulff /|\ Wulff Photography & Design /###\ mailto:henningw@archiphoto.com |[ ]| http://www.archiphoto.com
