Neither of those two scanners can do 16bit. Both are 12bit.
I don't have the scanner but the math should be pretty simple. If the limiting factor is only max. filesize (3.5G), saving to tiff (lets assume plain format - no compression) uses 16bits (2 bytes)...

Well, you CAN do it without the tool. All you need is a drum and lots of time since you won't be able to do adjustments in "real time". Instead, you bring the drum in position (so the drum is between...
FYI, you can put together a PC and use a number of SCSI cards that are proven to play nicely with Howtek scanners. All that for half the cost of a Ratoc SCSI-USB adapter alone.
I posted what I have a few posts back. I'm not aware of any other version of field service test for 4000/4500...

Can fellow DPL users share experience on max. horizontal dimension (in direction of drum rotation) of scans with DPL?
Whenever I scan anything that is longer than 10.992px (so that would be like...
Replacing Fusion drive with a SSD in an iMac is not something you can do on your own without voiding warranty (besides the fact that it involves a few steps that could easily damage the computer).
I was having an intermittent problem with banding in red channel. It would cure itself eventually (well, I did various things like changing bulbs, cleaning and greasing the rails and lead screw,...
Isn't Precision II 5.760dpi for 35mm, 3.200dpi for MF and 1.800dpi for 4x5" film?
Thank you!
Not sure if I will attempt to open the shutter to find out what's broken, though...
Newbie in LF here.
I got a Rodenstock Grandagon 90/6.8 with Copal 0 shutter from eBay a couple of months ago. Not knowing this stuff I thought everything was OK, until I developed first film...
