There is (to my knowledge) only one color negative 400 ISO available in 4x5", the Kodak Portra 400NC. I have used it for star trails photos and it works pretty well (really a lot of stars...). You...

The film holders of the D2400UF are in my opinion very well designed. The film is not touching at all the scanner window, and I have never seen Newton rings even on 4x5". I suppose this is one of...

I have tried the Fuji Quickloads for a while, but I found it inconvenient for the type of photography I am doing, i.e. travel and landscape photography. Three reasons for that:

I was told when using the Polaroid scanner that it was truly a 4000 dpi model which, considering its price, was possible. I did not check by myself on the web, but I should have.

For information, I have made a short comparison between two inexpensive flatbed scanners for 4x5", the 'old' Epson Perfection 1200 Photo and the new Canoscan D2400UF, and one film scanner, the...

I have also a pair of scanners: one film scanner for 35mm only (Canoscan 2710F, $500), and a flatbed for the medium and large format scans (Canoscan D2400UF, $500). They are providing very good...

Hi,

I have found today after a number of unsuccessful searches some sample scans of the new Canoscan D2400UF, announced at 2400 dpi optical resolution and $500. Here is the adress:...

Thank you for your comments, I will try this system (at least to see if it really works). Here is the way I think I will make the tests (as soon as I have some time available :-)) :

I am thinking of buying one of these small and cheap ($20~) laser pointers to use it as a focusing aid in the dark. They produce a fairly small and very bright red dot that can be aimed at the...
