This is genius! Thank you so much. This will save so much money. I’m going to make an 11x14 pinhole camera and use this design for the film holders. Could you make a vid sometime on how you made the light trap for the dark slide slot? I can’t quite figure it out.
I think I made one already. But I will check. The light trap isn't there: the darkslide slides up but not all the way out. Thus keeping the light out. Another way is to use velcro or felt to line the top. But normally you would take out the slide and place on top of the camera above the darkslide opening to block off the light. But that won't work for a ULF camera. Oh now i thought about another thing. You can make the darkslide with the bottom part hinging with a fkexible tape. So when you pull it all the way up it hinges and you can fold the darkslide over your camera without completely pulling out the slide.
If you are going to use film, you really need a propper light trap. Maybe a little flap that is under spring tension. For me the filmholders never gave any issue since I only work with paper negatives which are not that light sensitive.
Thanks so much! I bought some 11x14 X-ray film. 100 sheets for $65. I’ll figure something out regarding the slot or just load a sheet inside a camera that I build and seal it in the dark to forego the film holder issue altogether. This picture frame solution that you came up with is absolutely genius. If the slot is my only issue, I’m 90% there thanks to you. Keep up the good work. So fun!
For the ground glass I usually tape the glass on one side (lens side) with scotch tape. But be carefull not to tape to close to the edge: otherwise the distance of the photopaper vs the lens won´t match with the distance from the glass vs lens. Or I go to the local home depot/ hardware store to get a pane of glass cut to size. Glass being opaque matt. Alternatively you can grind the glass that comes with the frame.
@@Dstonephoto that is a good point, but mind you the filmholders you can buy aren´t exactly high tech things. As long as the backplate is straight then it´s ok. Don´t forget when putting the photopaper or film in the frame it will be pressed against the sides of the frame. As long as your picture frames are all identical there will be no issue. It will be flat. The frame is designed to keep dzveloped pictures flat in the frame. The big advantage of this method is that the film plane will be at exactly the same distance as the ground glass plane (ground glass being the glass from the picture frame itself).
@@sneeuwwolf1176 Agreed. When I initially started down this path of 4x5 I thought film holders should be a relatively simple concept. But the discussions I found about them were insane and long-winded. Whether that's mental gymnastics or not is the more important question. Who knows, maybe it's like lens sharpness or portrait focal length or color science discussions. You're right, it's just a box with a frame which presses the film flat onto a surface. This isn't quantum mechanics. I saw an interesting post where guy had added ground glass inside the film holder as a failsafe way of ensuring focus. (genius). I've thought about making/modifying my own film holders which would double up as a film holder you can subsequently dunk into a developing box. TBH, as someone fairly new to film I'm surprised there aren't smarter and modular devices manufactured in order to eliminate some of this seemingly absurd redundancy which just adds more points of failure (and frustration). It's wild to see what mechanically dumb devices like Jobos sell for vs what an automated inkjet or laser printer can do. I should have gotten into classic motorcycles, instead!
@@DamanDamish definitely give it a try. It´s not easy, but very rewarding. I did it because I wanted the feel of 19th century photography. Now building a second one.
@@DamanDamish yea sorry. Didn´t post it yet. I used a strip of velcro tape (one side sticky, the other velcro..). So make a backboard, then a U shaped frame on top of that. Then a square hollow frame on top of that. On top where the U shape is you can put a strip of velcro tape. Glue it all on top of each other. And then you can use a square piece of black card board as a darkslide. I really should make a video on how to do this. You also can make one with 4 boards those are heavier but also will block out the light.

@@ryanmaloney9403 well, glad I could help out. If you got any more questions don't hesitate to ask.
Hello, Thank you for this nice video and the easy way to make a film holder, I will do it. How did you make the glass of the ground glass ?
For the ground glass I usually tape the glass on one side (lens side) with scotch tape. But be carefull not to tape to close to the edge: otherwise the distance of the photopaper vs the lens won´t match with the distance from the glass vs lens. Or I go to the local home depot/ hardware store to get a pane of glass cut to size. Glass being opaque matt. Alternatively you can grind the glass that comes with the frame.
Am I missing something or is there a second video missing? I’m super intrigued. Are you in Belgium or NL?
What would like to see me make/ explain? I skipped maybe a thing or two.
@@sneeuwwolf1176 From what I read online one of the key challenges with film holders was that of film flatness.

Hello again, you say you have other videos on making film holder. But I can't find them.
I have, but it´s not online yet I think (I need to check). I will make a new one for very cheap and easy film holders soon.
@@sneeuwwolf1176 thank you for your videos. It push me to make my own 8x10 camera

@@sneeuwwolf1176 Hi, I start building mine :) How do you plan to make the light trap ?

Bro u just got a new subscriber
Thank you!
Don't say thank you that is what I should say
To you
@Sneeuwwolf what is exactly the black sheets material that you're using? When you slide it makes a sound like acrylic sheet and looks like it!??...
No no it´s hard cardboard from the hobby/ art shop. It´s quite hard and stiff. Very easy to use. I´m going to try and find the name.
@@sneeuwwolf1176 thank you for your reply. I would like to know the name of it please!
