Re: filmscanners: Canon 4000 scanner VS Nikon LS4000 >Mikael
Its the same problem with my 2 scanners ls2000 and Ls 4000 regarding sharpness/ dept of field problem. If you are pleased with your Ls2000 stay with it and wait and se what's coming. The difference between LS2000 and a extrapol. picture from 2700ppi up to 4000 ppi and real 4000 ppi from Ls 4000 are not huge. In fact I have done some test pictures and asked other photographers which one are a 2700ppi picture from the beginning. No one could se and tell for sure the difference from the 2 scanners, Fuji 100ISO slide film and 30 x 40 cm copies . The noice is lower and colors are better in LS4000 than LS2000.

Mikael - thanks for this useful info. It is interesting that the different generations of scanners have the same depth of field although they have totally different optics. Means that Nikon must be holding a firm line against other constraints (such as LED brightness).

The "analog gain" option in NikonScan only changes the CCD exposure time. I've traced the commands that NikonScan sends to the scanner, and the field it changes is definitely the CCD exposure time field. In addition, the scan speed is proportional to the "analog gain" setting, which it wouldn't be if NikonScan were only changing the brightness of the LEDs. Regards, Ed Hamrick

Nikon might be approaching the limits of linearity in the LEDs. They also need to be able to have a range of brightness available to them for the "analog exposure" they offer. Since Blue LEDs are (or at least were) the least bright, they might be the limiting factor. Art Julian Robinson wrote: > Mikael - thanks for this useful info.

It would get irritating, Ed. You do good work!
