home made negative scanner (sort of)

March 21st, 2009 by richard

For a while now, I’ve been trying to get a flatbed scanner working, to no avail, to try and create a long time pin hole exposure shot like Justin Quinnell.

The other reason for the scanner was to create contacts sheet from negatives that I have, to prep some scanning sessions on the negative scanner I got for my Dad recently. So then I got an idea…

What if I simulated, my own scanner, well sort of!

  • The idea goes as follows.
  • Create a white image that fills the entire screen
  • View the white image in full screen mode, you might need to maximise the level of brightness and contrast
  • Blue tack the negative holder to the screen
  • Take a picture with regular camera of the whole sheet, or individual sections of the negative sheet.
  • Load pictures onto PC
  • If working from black and white negatives, convert the image to greyscale
  • Invert the image – hey presto!
  • Depending on the quality of your negatives, you will have to adjust a) levels b) curves to get the best out of the image.
  • The overall result does not give you highest quality image, but it is certainly not bad for no extra cost or extra hardware.

Here are some example shots

Overall, a rather good result
