Re: [Digital BW] Re: Scan a roll at a time

Hi Lew,

The lid has a light source for transparent materials and there is 
another for opaque things in the box - and you tell the software which 
you are scanning.

I've used several types of page over the years, but mainly the 
Clear-File brand which are more or less as the name suggests. Also some 
others slightly less clear. Both seem to work pretty well. The only 
things that don't are the old glassine? paper ones, and I simply re 
rehouse the negs in clear filing sheets. Some of those old filing sheets 
are falling to pieces anyway, so it seems a good idea in any case.

There might be a very slight loss in quality, but they certainly look 
pretty good on screen - and I did a batch to send to a museum earlier in 
the year and they were find. You do have to carefully set the black and 
white points to get them right, as the auto setting on the scanner which 
works fine for most things will try to reproduce the empty areas outside 
the film as well, and you have to limit it to the range on your negs.

I've not had problems with Newtons rings. Probably the dust on my negs 
helps:-)

Regards,

Peter
