[filmscanners] RE: Flatbeds for 6x6 negs.



Charles,

I use the Expression 1680 pro. The purchase was made just after the 2450 was
launched in the UK - my decision to go for the 1680 was based on a
discussion with technical support at Epson - the question to them was what
do you get for your money in the 1680 Pro over that found in the 2450. They
highlighted 3 main issues :

1. Dual focus mechanism
2. Higher Dmax
3. Higher quality interpolation in the scanner when used 1600x3200.

I do not regret the purchase. I have no focus problems and no issue with
noise. The scans a as sharp as a tack.

Hi,

Everyone with Umax Powerlook III seems happy.  The reason I was finding the
Epson 1680 more interesting is that is does 1600x3200 dpi as opposed to the
Umax 1200x2400.

Will that extra resolution of the Epson transfer anything from the negative
to the electronic image or will it just generate more noise?

Ta.
Charles
