My new LEGO film scanner

I recently decided to go back to film from digital. Unfortunately I sold my film scanner years ago and just don't feel like buying a new one. They're painfully slow anyways. So I decided to make a negative scanner out of LEGOs.

I originally used my 5DIII and a 24-105mm + extension tube. The fit was absolutely perfect, unfortunately the 24-105mm wasn't sharp enough. I then switched to the 50mm f1.4 + Ext. tube. That was much sharper, but the resolution is only about 6MP because I have to crop a bit. The final result is my T3i and the 50mm. The neg fills the frame, so I get 16MP files.

I use a blank page on my laptop as a light source and since the rig is very stable when leaning against the lens, I can shoot for 1/2s easy.

Just a word of advice when converting negs to positives in PS. Set your white balance by clicking the edge of the film strip (RAW files of course). Then convert it and cmd-I and auto levels. Just make sure you crop before otherwise the Auto Levels won't work well.

The result is sharp hi-res files.

Two of my loves - Lego and photography! Thanks for the idea. I might modify your design to accommodate a tablet to be used as a lightsource.

Not a great example but here you go. Just scan, convert to JPG, Invert and auto levels. I'd fine tune the color a little though. I had a real hard time getting nice results until i figured out the eyedropper on the film strip trick. Most tutorials have you do that on the JPG.

Here's another with a 100% crop to see the grain (ASA400)

Not bad at all. My own results in the past were much worse, and I gave up and went back to scanning. Mine were BW film though.
 
Brilliant idea. I've been toying with "scanning" some slides with my 5D2 lately, and having a box of old legos somewhere around the house, I may just have to try this.
 
Another one...

Another one...

My setup is quite similar. I made it a few months ago, while waiting for a new camera…

It is made to hold e 6x6 film frame in front of a iPad 3 with a complete white screen. The film is gently pressed between two stripes of rubber foam. The camera is a Leica M with an adapted Olympus 50mm f3.5 Macro lens. Before I finally got my finger on that lens, I used a Olympus OMD with the unbeatable 60mm Macro, but I find the 50mm Olympus easier to handle for this setup.

Before that I had build a similar thing for 35mm film and before that one for 35mm dia frames.

I'd like to build one for all with a changeable format-holder and a special holder for the iPad, but I currently do not have the right Lego-parts.

The example is just half an hour old, made it quickly to show it to you. See, what can be done with a few plastic bricks… No need for a big scanner. :D

Brilliant.
Have you tried shielding the stray light between film and the lens using black cloth (or black lego pieces)?
Would that not improve the exposure?

I tried that with my first Lego scanner using a tunnel of black stones. But the Lego bricks reflect the light like mirrors, total desaster... I think, black cloth might work, but the iPad-back-light works pretty good, because it is very bright.
 
Hm. I've been giving it some thought (re-shooting my negatives with a DSLR) lately, recently I acquired a Nikon D600 and have some Tamron Adaptall lenses that are real sweet in macro mode :cool:

Never occured to me to use Lego:bang: and now that I see this in action, I might give it a try someday soon! Question: would the sharpness not be enhanced with the use of ANR glass to flatten the negative with?
 
I also tried using a flash instead of the computer but can't say I saw any difference. Don't think the ambiant light was a factor for me.

I have not tried it, yet, but I bought a package of 6x6 dia frames with ANR glass a few weeks ago to do exactly that. I already managed to carve one of the plastic frames so that I can clip a three-image-film-stripe into it. But during the summer weeks, I am more out with a camera to shoot, and all those little projects are on hold.

But this thread is very inspiring, so thanks to laskadog, I might work on it a little bit.

Obviously there are more people, who build Lego-scanners. Maybe we should try to share, how to build them, to help each other coming up with a good construction?
