I learned in in HS in 1970. Then had if for a few classes after that. Essentially never used it since. but stull remember it.
Now if I could remember my German words I've been using in excersizes weekly for the last four years.....

I like to think I've learned something over the years.....

It seems to do a better job that the cheap 35 mm scanner I was given. It will do a variety of formats. See their site for details.
Of course it is slower than the small 35 mm version. And really slow if you crank up the dpi....
