Selfmade smartphone scanner from the scrap materials

7

Once I had the desire to scan film right now, but it was midnight and i decided to use the old soviet enlarger. I was surprised by the result.

However, I wanted to improve the results:
- Increase the resolution,
- Use smartphone camera,
- Get rid of vignetting associated with a condenser enlarger,
- Have a fun with color balance.

Later, from scrap materials (boxes from old CD) and LEDs I made a smartphone film scaner. The design of the device is as follows:
- White, green and blue LEDs are located at the bottom of device. Brightness of each color group can be increased\decreased,
- LED lights on the frosted glass, film is pressed against the glass
- On the stand is a smartphone which looking by camera at film.

I solved the problem of the “blue” photos. Negative film has a red substrate and the positive picture from it is always blue, and if you use the auto white balance on the camera, the red and green colors will be a lot to lose in shades.

    Brilliant! Thank you!
    So... the controllable light (white, green and blue) is in one box together with the batteries to power them. I really admire how you set up all the cables to control this! On and off switch! This might be the worst part for me;).
    The light then shines trough a second box on top to guide the light to the film that is on the matte glass/frosted glass. Did you leave the space above the LED lights open to shine up trough that? Or is there glass also?
    Can you share the type of the LEDs you used for white green and blue?
    Then comes the film on the matte glass and the final box that the smartphone is standing on. This part at least I got:). How did you choose the glass type?
    Thank you again and sorry for so many questions!

    @kattyz, thank you ^_^
    The second box - just a box with foil walls to light was smoother and brighter (minimal brightness loss). LEDs most usual, like this: rentechno.com/assets/images/articles/leds.jpg
    I just grind off their hats (for smoother light and good reflections) by the nail file )))
    A matte glass I took from the enlarger. It should homogeneously diffuse the light and be a perfectly flat, all defects will appear through the film, because this glass is a film's background.

    Thank you for your questions ^_^ and sorry for my low-level English *shy*

    I'm an economist (graduated university), but i'm working as engineer-programmist :)
