Taken with a Polaroid model 100 using Litho film.

Polaroid model 250 with 4x5 back and 3D printed double sided film holder: 861g
Voyager heavy duty #10 tripod: 1010g
Since it's a point and shoot rangefinder, a ground glass is optional. Manual...
I'll look into garolite--where do you buy it in this format? And I like the way the corners go together--with overlapping joints. And the pictures you posted are a film holder? Or plate holder? I...
This isn't a plate holder--but getting the film out is an issue. I normally use a plastic spatula like tool to ease the film up so I can grab it, but I'll look at those finger notches--sounds like a...
I would use either tin or aluminum, or thicker folio vinyl if you can find it.
Wow! that's pretty expensive. It does take almost 1/2Kg of filament, and it ties up a printer for a long time. I was thinking this could be economical, but $227 could go toward a few used 8x10 film...
So yes, they are designed to print vertically. I'm not sure what you mean by finger recess...
Yeah, dark slides are tricky. I haven't printed one of these yet, so I'm note sure what I would use...
I've been on a roll designing film holders for 4x5 and 5x7 that can be 3d printed. I think the most difficult challenge is what I refer to as the pressure plate, which puts pressure onto the dark...
I adapted a shutter tester on GitHub to work autonomously (instead of requiring a computer) using existing code and it seems to work accurately at least until 1/250, though I did get measurements of...
It can be a challenge to find chemicals in Canada, but FLICFILM (Longview Alberta) manufactures lots of photo chemicals and distributes them at The Camera Store in Calgary. They even make CD-3!
If...
I like this idea. I was thinking a backpack designed for carrying a child could be adapted to do this. I have a 17 lb 8x10 camera I want to lug around...
Here's what I wrote up on my Instagram (@hackaninstant):
Need an inexpensive large format shutter for your lens? Here's one you can build yourself for around $10CDN. All of the resources to build...
I like the idea--it's portable, and looks inexpensive. I made a dark box out of black foam board with 2 arm holes and a sliding door that has light seals (180 degree turns), but it isn't portable. It...
Just finished designing/producing a circuit board for this project, which is posted on GitHub (link in first post). This makes it much easier to assemble the parts. I'll be designing a 3d printed box...
Posted some videos on the Github project page.
Yes, this would be possible in the software. Since this shutter is controlled by a servo, you can limit how many degrees the servo rotates during a shutter cycle. With this shutter, the typical value...
The narrow/wide rib sizing is interesting. Once you determine the total rib size (from top fold to top fold), then each side size (remembering to subtract 1x the fold size from the sides), then draw...
I just used household blackout curtain fabric. It's white, but it was what was locally available for $10/meter (in Canada). It's somewhat of a thicker fabric, but I liked how it turned out for an...
I was thinking about what could be done to make this shutter design faster and here are a few ideas:
1. Make the servo gear bigger so the servo doesn't have to spin as long to open the blades...
I made a 3d printed leaf shutter that's servo actuated and controlled by Arduino. I posted the project at https://github.com/hackaninstant/Servo-Shutter
Fastest shutter speed is 1/8, so it's...
I made double sided 8x10 film holders, using softwood for the edges that contain the darkslide grooves (cut by table saw) and 1/2" plywood for the body, though I'm thinking 3/8" would work as well. I...
Wow! This looks quite comprehensive. I just built a simple laser shutter tester using an arduino and am encountering the limitations--I really like the idea of measuring the shutter speed by...
I love this type of innovation! I saw that video and I'm currently gathering the stuff needed to build one. Of course, every forum seems to draw naysayers who are dedicated to the status quo. But...
I just built an 8x10 camera out curiosity as to how much better it is than 4x5. I shoot paper negatives, which don't contact print the best, so I tried a b&w reversal, directly shooting the photo...
Wow! That camera looks great! And I see what you mean with the holes. I think since I used hardwood, it can tolerate some holes, though they probably won't be as closely spaced as yours. I'll have to...
I'm thinking that a modified child backpack might work. They're designed to hold up to 30 or so pounds, and the newer ones have pretty good waist and back support.
I'm thinking that what I should do is get ahold of a wooden 8x10 film holder and see how it's built. I think I built mine quite differently than standard, and they were built for expediency (just...
You're the second person who has suggested drilling holes. If I did this, I would likely work on the base and focusing slide since they probably contains 1/3 of the total camera weight. And I suppose...
I was hoping to find a backpack somewhere-- I have a few locations I want to take this, so it needs to be designed so it won't wreck my back, or the rest of my body. The camera weighs around 6-10 lbs...
I've shooting regent royal hard dot film on a Polaroid 110A converted to 4x5, then developing them in D-23. I find exposure is pretty critical, otherwise the negative is too dense or too thin. I...
Who knew making a bellows could be so dangerous? I mean, by using spray adhesive I've apparently cut years off of my life. And apparently I'm lucky nothing exploded during its assembly.
Really,...
I just made a bellows and used PVA book binding glue to glue the ribs on, then used Elmer's spray adhesive to glue on the lining. With the spray adhesive, you only have 15 seconds to lay down the...
Yes, I did use blackout curtain fabric. It was inexpensive ($10CDN) and seems to work well. I did make a big mistake on it though--I wasn't aware that I needed to alternate the narrow/wide ribs...
Here's the very first picture I took with this camera:

It was supposed to be a paper reversal but I put the paper into fixer instead of sodium sulfite for the clearing bath :p It didn't...
Here's an 8x10 camera made out of a coffee table (I did a separate post on it but thought I should add it it this one):
237269
Pretty much everything was home made except for the lens elements,...
I made the film holder first, then measured the film offset and built it into the ground glass offset when I made that. I've used both the ground glass and film holder on another DIY sliding box...
The light trap just has felt at the opening and no, the slide can't be fully removed or light will get in. Some day I'll study a real film holder to see how it works and maybe try duplicating it....
I came across an old coffee table and picked it up for the 3/4" hardwood in it with an 8x10 field camera in mind. As I glued the body together and put the wooden pins in, I was wondering, how DIY...
Sounds like a great idea but point and shoots normally don't have infinity stops that are able to be modified. Even Cameradactyl's OG point and shoot 4x5 camera doesn't work with this back--you would...
I like this idea for field developing, though the film plane offset is problematic for point and shoot 4x5 cameras. I'm wondering how difficult it would be to design this with a dynamic film plane...
