I have just made my first medium format scan with my new Konica film scanner, and I have to say that I am very impressed. The native scan resolution of medium format film is 3200dpi (4800dpi for 35mm) and I scanned the 645 black and white negative as a 48bit colour file, saving it as a .DNG file. The output at 300dpi was roughly 60cm x 50cm with a file size of 300Mb (RGB).
I have been very keen to get this scanner since I purchased it from a seller on ebay in the USA. Thanks to a friend currently living in New York (and some other friends who were kind enough to bring it back to Aus with them), I managed to get around the expensive part of shipping the scanner here to Australia.
Comparatively to the Nikon 8000 and 9000 scanners, the Konica is much smaller, which makes moving it around much easier (it is roughly the size of a regular shoe box). The scanner took a few minutes to prepare itself and with VueScan the scan took about one minute (with another 2-3 minutes to process the .DNG file). The scanner come with SCSI Ultra and Firewire 400 and it worked flawlessly using a Firewire 400 to 800 cable on my Macbook Pro.
The negative I scanned is a portrait of Tim Keeble and Dennis Mortimer, the duo behind the recently closed Artists' Shed in Queanbeyan. The photo was made in 2013 at The Phoenix in Canberra before the bar was closed due to a fire in an adjoining restaurant. Dennis and Tim were both instrumental to my photography gallery The Photography Room starting a few years ago at the Artists' Shed and I have a lot to thank these guys for. Perhaps this portrait will be a good start.
I have more rolls of b&w 120 than I care to count, and needless to say, I have many hours of scanning ahead of me. But with results like this, it's not a bad thing at all.
