[filmscanners] RE: Lines in scans



HI, All!

I think I can safely say that dust/debris/bad pixels on the CCD will result
in lines along the direction of CCD travel (or film travel) and
processor/bus contention (lost data in bursts) will be perpindicular to the
CCD/Film travel axis.

Oddly enough, my flatbed scanner, a Umax Astra 2400S will have lots of
(generally Magenta colored) lines along the scan axis on the first attempt
at scanning after power up, which go away upon subsequent scans.
(regardless of what software I use!)  Never figured that one out, but it's
not a big deal, since I do 99% filmscanning now (Scan Multi II)

Hope this helps!

Guy

Here it was definitely some background utility I was running. If only I
could remember what it was! But once I removed it, the lines disappeared.
