I've never noticed an issue with reading the fiche I have - but then most of my fiche came with the reader and so obviously matched up. But I do have some fiche that came to me separately (not all DEC fiche, but all DEC-related) and that all looks good too. How can you tell whether fiche is intended for 42x or 52x or whatever? (I had a quick look at one or two and I couldn't see anythig obvious ...) BTW: I did semi-catalogue what I have (i.e. listing the fiche part number and the documents contained therein).

That's true, but Al was talking about programs processing those images. While the file may be compressed, when opened and read into memory the full uncompressed image is generated. And it might well be a byte per pixel even for B images, because that makes the code simpler and much faster. That said, images in the 100 megapixel range are not much trouble for modern computers. Lots of gigapixels, that might be different. paul

Just a stupid question, as we are on the microfiche again ;-) Is there no "modern" format of TIFF or similar, which could save the whole microfiche as one picture?

Re: Micro Fiche Library.
This is the one I have. It may be overkill because I think it goes to 8 x 10 transparency. A 5x7 format scanner will work just as well for fiche. If you plan to do aperture cards, you will need a longer dimension that 7" to cover that. The Epson 4990 apparently has that. i looked forward and saw Jorg's posting as well. If you find a good fiche reader that may work. Your current reader may work if you can get the image quality up enough. Here is one fiche I scanned, a WW2 unit war diary. It was done with the V800 scanner you mention and my method of a previous post. I think the results are pretty good. thanks Jim http://vpb208.org/diary/fiche1/page_01.htm On 10/4/2016 10:48 PM, Rod Smallwood wrote: On 04/10/2016 16:53, Dave Wade wrote: Jim mentioned that dedicated microfilm scanners are expensive.

Re: Micro Fiche Library.
I could scan a fiche in about 10 min with an Epson transparency scanner. I think Al may have an actual digitizer but they are expensive. As to the fiche reader you got, I've never seen one with a plastic carrier. They always had glass in my case. On the one I have you can pop out the view screen, and the lens is about the size of a small microscope objective. Mine came with one for fiche, and one for aperture cards. The lenses were easy to slide out and swap. See if you find one for the scale you need for DEC on epay maybe? I am glad you have the magnification value, I've only had ones which were multiples of a base size, so 1x, 1.2x etc. The Epson I mentioned has the XP era driver to allow their software to create a template for scanning. Once you have identified the size of a page on the media, I found it easy to just move it to plop over top of each of the other images, then could scan the fiche as fast as the scanner could run. It was one of their Precision models which could do 5.7 transparancies. I created a small guide to position the fiche itself in the same spot, so I only had to build up the template once.
