Today’s Tech Tip: Help For Scanned Microfilm Images That Won’t Open — 7 Comments

  1. A microfilm scanner is a new piece of equipment to me. None of our local libraries (that I know of) has them. Do they come out clearer than the print versions? I ask because the microfilm printers at our state archives library always seem to have dust, lint, strands, and flecks on the screen which show up on the printed copies. Oh, for clear microfilm images! Thanks for the tip. I’ll remember if it I ever have the opportunity to use a microfilm scanner.

    Aside from converting tiff files to jpg, what do you think of Irfanview?

    • Hi Nancy,

      As I’m sure you’ve experienced, microfilm readers rarely print with the quality that we see on the screen. Some printers are better than others, but all in all, unless the film is very crisp and clear, the printed version of that image may not be of the best, most readable quality.
      The microfilm scanner software, on the other hand, captures the image almost exactly as you see it on the screen. If the filmed image is not the greatest, scanning gives you some more options. Once you have the image in the computer, you can see what it looks like and then manipulate brightness, contrast, and other parameters to make it more readable. Even if you only want a printed copy, this saves you the trouble of dropping another 25 cents each time you would have played with the darker/lighter button on a regular printer — and ultimately, you have more control and get a much better image. And you don’t even need a single coin (unless you are also printing it)!

      Of course, you also have the option to just save that image to a flash drive, and you have a permanent digital image that you can them edit using Photoshop or whatever other software you would normally use.

  2. Chris, are you saying that you saved jpg files with tif names? If that is the case, you could just rename them individually. It’d take longer, but not require an extra program. Of course you’d need to know that. 😉

  3. Hi Jean,

    The scanning software (CapturePerfect) gave you the choice of file formats (tif, jpg, pdf, and a few others). I didn’t look at all of them, but with tif selected as the format, you had a choice of saving it with no compression or with jpg compression. Starting off, I was saving it without compression, but it took so long to process that I changed it to use the jpg compression (but it was still a tif file).

    I did try renaming the files to jpg, but it wouldn’t open them that way, either.

    In retrospect, I think I should have been scanning at a lower dpi (300 instead of 600) and saving as uncompressed tifs. (Side note: scanning at 600 dpi also required the reader to actually scan it twice. 300 dpi was done in one pass.)

    And an update about deed platting is forthcoming 😉

  5. Irfanview is my favorite batch conversion utility. It has saved me tons of time throughout the months I have used it. Please, anyone who tries it to convert files, save the results in a new folder. Certain errors choosing settingscan cause pain, don’t let this happen to you.
