I think it's worth pointing out that in all the Nikon Scan TWAIN controllers I've seen, the "Output Resolution" defaults to "1350 pixels/inch". Hoever, it is fundamental to realise that this is at the default output SIZE of 1.79x2.64 inches, ie 2x the size of a 35mm neg. On this setting the scanner is scanning at maximum optical, 2700 dpi (1350x2). I have often seen people put the output res box up to 2700- without changing the "output size"- and thus scan at an interpolated 5400 dpi. As has been pointed out, optical is real info, interpolated is not. Quite why Nikon do this, as it seems a bit of a pitfall for the unwary, I don't know. And I'm not saying that either Pascal or anyone else is unaware of this. However we have trained a number of people on the Nikon, and they always get caught with that, so I thought it was worth flagging up. The correct way to control the scan res on this TWAIN interface is to leave the defaults alone and adjust the scaling- a horizontal slider under the output res box. Hope it helps Cheers Rod
