In short, I am satisfied.
I scan flat and do all of my processing in photoshop. Including cleaning, I don't use any of the scanner's presets. This scanner will scan every scratch and dust particle, and you will want to firebomb your local lab if you are not processing your own film.
The drawbacks are:
Grayscale scans lack depth.
Film holder could be much better, no way (so far) of scanning the negative borders (I'm thinking of cutting my holder)
Every defect on the negative will be visible. (I decided not to use any of the built-in dust removal technology, I prefer to do it by hand and have a sharper scan)
On the plus side:
Cheap
Responsive Customer Service
"Sharp" scans (almost scans the grain)
Small and light (almost portable?)
Fast
On the sharpness side, I've been using a little bit of unsharp mask in photoshop, but after viewing them on
my flickr, I find that there is too much edge contrast. It might be the conversion from .psd files to .jpg.
If you do have a look on my flickr, all the negative without the edge are scanned by the Plustek. the few that show the border are scanned by drum scanner. And please excuse the mess, I'm in the process of organizing all of my pictures.
I'm certainly satisfied for web and small prints, I have not tried large prints with it yet.
Hope this helps.
