- Despite the fact that he doesn't need another pinhole camera, Joe builds a wide-angle 4x5 camera that accepts cut film holders, for the purpose of shooting landscape images onto sheet film.
Hey joe, ive finished my build and successfully took photos for my university project, i want to thank you for answering my questions😊 The photos came out way better and sharper than i expected and im extremely impressed, thank you again
Congrats, well done!
It's like watching an Adam Savage one-day build! :D
thanks for the continued inspiration Joe. I love your experiments.
I find your creativity and inventiveness refreshing, Joe! Your idea of placing the filter internally is a great way to control flare. I have a series of 10 or so square plastic filters that could be placed internally, to improve my black and white paper and film negatives. Thanks for making use of your scrap wood pile! Your creativity has inspired us all.
Great video Joe, thanks for taking to the time and effort to share your knowledge on pinhole cameras.
Great project Joe! Looking forward to the pictures with the sky and clouds.
Another good Build -- Well explained and well presented. Thank You, Joe.
I’d never thought of making a wide angle pinhole. I have made a pinhole lens board for my Graflex Speed Graphic, and I’m waiting for a sunny day to test it out!
Wow thats an awesome camera. I had just started building a 4x5 wide pinhole camera myself, but this design made me start all over. Your ideas are as always brilliant. Thanks for another great video, and by the way, love when you shoot in your world famous backyard :-)
An internal filter is an excellent opportunity idea, Joe! That eliminates so many quality issues! I'll try that too, using some 2+2 inch filters I have on hand. Thanks!
I am looking forward to featuring the World Famous Back Yard in my video on the scanner.
I love this camera so much. It's a real illustration of how you can build excellent cameras with just what you have around the house. It looks incredibly solid and well built. Excellent for doing exactly what it's supposed to do. Next time we go out, I am going to make you use the nikon and steal this camera for a day!
I like the pressure plate idea. When I'm designing these things is it always the pressure plate I struggle with.
Thank you for a very interesting video! I have long wanted to make my pinhole camera 4x5 :)
Thanks for the video.
I have two 4x5 inch wide-angle wooden pinhole cameras that are very similar to yours. I had been considering adding a red or orange gelatin filter to mine and did get some good ideas on how I will do it. Thanks !
That's pretty awesome. Cleanly inventive.
Nice!! Hope to see the film results soon.
love this and really thinking about trying to build one for me and my little girl just to show her what can be done
Awesome stuff! To be honest, I thought with this kind of pinhole the image that comes out would be pretty soft, but I am impressed by the overall image quality and sharpness! Really makes me want to build one myself too...
for a sharp image, having a well formed pinhole is really important, as is having the pinhole size matched to the projection length (distance from pinhole to negative). give it a try, it’s great fun.
Those “developing trays” are a great idea. Might actually be able to do 11x14 in my bathroom.
thank you!! , is very interesting and very captivating see your videos, you care all the details, sooo you have a new ''suscriptora'' !!! from Chile. Keep going! your videos are very usefull :)
Great video and project on one of favorite channels :-) I’ll try to copy your design adapting it to 5x7” as I have a load of film holders, I got very cheap. And recently got some 5x7” infrared film, that I would like to experiment with.
On my wood pinhole cameras I tap 1/4-20 threads for a tripod right into hardwood (usually oak) and have had no ripped out threads or any trouble at all really. My tripod is a cheap Slik Sprint with a quick release head.
Pretty cool. Considering my fascination by the technology of bygone eras and that I am a novice photographer, I may want to delve into pinhole photography someday. Sadly, my budget will not allow any more hobbies right now.
If you have a camera with interchangeable lenses, you can put a pinhole in a body cap and have fun now for just a few minutes work.
Joe, First: Love your channel! I am duly inspired, and a little intimidated too!
I am a newb in the whole pinhole realm, but I do have a thought for you as a result of recently acquiring a circa-1942 Baby Brownie. I bought it on a whim, thinking I could maybe make a pinhole camera out of it. Now that I have it however, I have fallen in love with the little thing, and find it much too precious and well-preserved to disassemble and drill into. But it did get me going on Brownie and pinhole research. Which led me to your videos, and your quest for efficiency in pinhole film/paper changing between shots. (I started with your film canister set and the tryptic camera vids posted last year, brilliant!)
To that end, a couple of things I have observed and read so far make me wonder about the idea of making a pinhole camera from a vintage camera, and figuring out a way to retain use of the film advance feature? I learned that some Brownies have a hold-open long-exposure feature on the shutter button. I also observed whilst removing the original film from my Baby Brownie that the two-layered film was surprisingly heavy and stiff, yet still moved easily between the spindles. Do you think it would be possible to attach individual square or rectangular pieces of film or paper to a strip of blackout paper, in such a way that it would be windable between the spindles? Maybe the individual film/paper pieces could be tiled so they wouldn’t catch? It seems to me that for attaching them in a non-permanent way to a blackout strip, perhaps one of 3M’s removable repositionable tape products might work? (www.walmart.com/ip/3M-Scotch-9415PC-Removable-Repositionable-Tape-3-4-in-x-72-yds-Translucent/729261819)
I am intrigued by how your mind works, especially regarding this whole in-the-field film/paper changing efficiency situation. The winding feature seems to me to potentially be something to take advantage of...? ...Of course I know next to nothing about all of this, so please tell me what I am missing, that no one I have seen so far has done this with their home-built Pinhole Cameras?
(I did find a pinhole camera you-build kit that uses 35mm film: www.bhphotovideo.com/c/product/1405826-REG/gift_trenz_40025_woodsum_pinhole_camera_maple.html )
You probably don’t need yet another pinhole camera design suggestion, but I thought I’d send my idea along in case you find it interesting...
Thanks again for your excellent videos, you have a new fan! ~Lorie
Lorie, welcome to the wonderful world of pinhole cameras. I've wound strips of photo paper on film reels like what you're suggesting, but the paper can get creased and it curls badly. I ended up making a camera with larger spools, from PVC plumbing pipe, the paper doesn't have bend as tightly.
Finding a Brownie-style camera with a bulb shutter setting is neat, for paper negatives especially. Instead of trying to roll paper into the camera, bring along a changing bag and use individual rectangles of paper cut to the right size.
Joe Van Cleave Thanks for the reply Joe! That makes sense, the paper is probably just too creasable,.... How did you like the PVC version with larger spindles?
@@noodgenoodgerson2660 It was a good design, the only hassle is cutting and taping the paper ahead of time in the darkroom.
How much to build one just like this but with an added tripod socket for portrait orientation? This is one of your best builds yet and I would seriously want to invest in one
Great project, so well presented. I want to build one just like it. Couple of questions: 1. Is black felt on the back of the shutter needed? Or is it light-tight as is?
2. How did you make your positive prints from the paper negatives? Contact print with same type of paper? Or something else? Thanks for another great video.
I think the felt is needed. If you make the pivot bolt tighter it might not be needed, but then the shutter would be harder to operate without moving the camera.
I did contact print the negatives, but used multi grade paper so I could control the contrast.
That is some nice work. I just wondered if/how I could make something similar and use a sinar zoom film holder for 120 film, and shoot some 6x12 cm frames. Will your camera also hold such a film holder?
Hi Joe. I enjoyed your video very much. I am taking an Intermediate Photography Course, and for my final assignment I want to make a pinhole camera and submit photos taken with the camera. I have a few weeks to complete. Your explanation and drawings are helpful. A link to pdf of your drawings would be even nicer. Also going from boring 3/4 inch hole on front panel to what appears to be a brass plate with f/300 pinhole, this I believe merits further clarification and demonstration.
He doesn't need another pinhole camera? You can never have enough pinhole cameras. This video has a lot of pictures to it. Another great video. Question: Does this high heat affect the chemicals?
I didn't realize how much I missed your build videos. Nice job. Simple build techniques and just using scrap materials. Perfect! What is the app are you using?
Pinhole Assistant, on the Apple App store.
@@Joe_VanCleave Great. thanks for the info!!
great job Joe.
I am in the process of making such a camera, but I need to figure the focal length with the lens aperture
Use online pinhole calculators to figure the optimal size pinhole for your focal length. For extremely short (wide angle) cameras like mine, figure the focal length is slightly longer than the shortest distance from the pinhole to the middle of the film plane, this will help compensate for under-exposure of the corners and edges from light fall off.
Also, it's not extremely important to use the optimal focal length, sharpness isn't always the primary goal, else use a glass lens. Sometimes, for longer focal length cameras, making a slightly bigger pinhole means shorter exposures with slow paper negatives.
@@Joe_VanCleave thank you very much..Bo
Hi Joe -- I discovered your videos over the holidays and have loved them! My dad and I tried to make the camera you make in this video, and it was such a fun project to share with him. Thank you so much for putting out this fantastic content.
I was hoping you could answer a question -- with the camera we made, the interior of the circular hole cut into the front panel of plywood is showing up on the negative. I can literally see the rough edges of the plywood circle etc. The image does not fill the negative like yours does, but I thought my dad and I copied your measurements exactly. (We just wanted a fun project and were intimidated by the math haha!)
I have tried looking this up online but am a little stumped. I think this is different than what is called a vignette, since it’s not a shadow, but rather actually seeing the interior of the wood circle cut into the front plywood panel?
Can you help me understand why that is happening? Thank you so much!
Most likely the front hole is too small. If you used thicker wood for the front of the camera, the hole would need to be bigger for the "light cone" from the pinhole to have a clear view all the way out to the corners of the film plane.
@@Joe_VanCleave Thank you so much for your reply! We used 3/16 plywood for the front as well. But I just measured the thickness of the front, and it's really between 3/16 and 4/16 -- maybe that's the culprit? I'll try making the hole a bit bigger and going from there!
I am really new to pinhole photography and loved your video, however will you please tell me how to install the pinhole lens? Is it glued into place or maybe I missed understanding. ty.
I prefer to use gaffer tape that’s black and light tight. Cut a small hole in the tape, stick the pinhole centered in the tape hole and secure the tape to the inside of the camera. This will allow you, at a later date, to remove and try a different size pinhole.
First of all: Great Video. It helped me with planning my very first pinhole camera. How thick is your brass material and does thicker (e.g. 0.5 mm) material affect the pinhole?
The thicker material could cause the corners of the image to vignette, depending on the focal length. The brass I use is .002" thick, or about .05mm.
@@Joe_VanCleave thank you for your answer but how do you measure the diameter of the pinhole?
@@larsesser66 I hold the pinhole behind a millimeter scale so the edge of the scale bisects the hole. Then, using a magnifying loupe I count how many pinhole diameters fit into 1 millimeter, then take the inverse of that number to find the size; ie 5 diameters means 1/5 = 0.2 mm diameter. It helps to backlight the pinhole.
Hi Joe, would you say that this camera or your nested box camera has the better solution for pressing the film holder against the camera body to prevent light leaks?
Using a spring-loaded pressure plate gives the most secure fitting for the film holder. This design over-engineers the spring tension in the form of metal springs, instead of the more common elastic bands. Some people just use elastic bands around the film holder with no pressure plate, but I've alway felt it more secure (and possibly a bit less leak-prone) to have a pressure plate.
The nested box camera uses a removable view screen where you install the film holder in place of the screen, hence uses a refractive lens instead of pinhole. This camera, being pinhole, doesn't use a view screen.
Joe how can i have one of your typewriters
How do you make the positive from the paper negative?
You can contact print the positive from the negative onto silver paper. Also, some people have built opaque enlarger heads that front-illuminate the paper negative for projection enlargement.
Hey joe 👋🏻 which camera are you using for making your videos
This one was probably using the LUMIX GH3. Lately I’ve been using the LUMIX G7.
😍
Hello joe, im attempting to build this camera for a university project, i do not own a film holder and i want to find a way to insert a photosensitive paper directly in the camera (inside a darkroom) and--> expose and then develop back at the dark room, any ideas as to how i can alter this specific design so that it works without a film holder and is still completely light proof?
Just build a camera where the back of it fits into the front half, and then you can load paper or film into the back half in the dark room.
@@Joe_VanCleave thanks for the reply, would something like your Ryan adney build work? If so i cant buy those part but im thinking of using a box joint method to ensure its lightproof but basically doing the same process as the Ryan adney build
@@dion9781 Yes, except with Ryan’s camera he had the back fit over the front, making the edge of the film or paper susceptible to light leaks. Instead, make the back fit into the front, making for a better light seal. Also, you don’t need fancy wood joinery unless you want to for aesthetic reasons. Black foam core board, hot glue and gaffer tape works good too! Good luck!
@@Joe_VanCleave I am going to make my camera out wood, I thought I should’ve done the joinery thing for better light proofing instead of just gluing each rectacle of wood into a box, what do u think?
@@dion9781 I’ve assembled cameras from thin, laser-cut plywood with finger joints, and the joints are strong, but make sure you seal them to be light-tight. It turns out with joinery you have a longer total length of joints than just assembling them as rectangles, so there’s more opportunity for light leaks. Use a flashlight and check each joint. Apply thin glue on the inside if you need to seal up a leak, then paint over it with black.
A question of a amateur, The photo paper doesn't need to be puting in the box in a total dark place?
It needs to be a darkroom safe red light.
Have you ever made a traditional film 4x5? I’m thinking about giving one a try. Something very basic, no movement s
With a lens? Not in 4x5, but I did make a 5x7 with foamcore and gaffer tape film holder, for paper negatives. Just a sliding box camera design, no bellows. Used a binocular objective lens from a 7x50.
Hey joe, im almost done with my pinhole camera, i made the design so that the paper is 20cm long and 16cm wide, the distance from the paper to the pinhole is around 4.8cm. can you tell me how big the hole on the wood should be and how small the pinhole should be?
Go to mrpinhole.com and plug in your focal length of 4.8 cm and it will tell you the optimal size pinhole. That’s optimal in the sense of sharpness, but you should know that with a very short camera with a wide film area, there will be some vignetting of the image around the edges and corners, and depending on how thick the pinhole material is, it can make it worse, so you should use very thin gauge metal for the pinhole.
As for how big the front hole should be, it depends on the thickness of wood you are using. I calculated the distance from the center of the film to the corner is 12.8cm (using Pythagoras theorem). You should draw out a right triangle with this as the base, the 4.8cm as the height, then connect the two to form the hypotenuse. Now from the top of the triangle (where the pinhole would be) measure down by the thickness of your front piece of wood, and then measure how wide the top of the triangle is at this point. This will be the minimum radius of the front hole, double that number to find the minimum diameter. I recommend making the hole slightly bigger than that to account for slop in the process.
@@Joe_VanCleave i just finished making the hole and i did a diameter of 2cm so i hope that works, im planning on using a needle on some aluminum foil and hoping it works fine😄 Thank you for your reply
@@Joe_VanCleave turns out we might have the same dimensions since i measured 12.8cm from the center of the film to the corner, i ended up making a 2cm diameter hole on 0,5cm wood, hopefully that will be okay. me pinhole says i should make a 0.29mm hole for my pinhole and ill try and do it with aluminum foil. im just not sure how to get that number with precision
@@dion9781 Any pinhole will make an image. But it often requires a few tries before getting one in the ballpark of what you want. You should measure the diameter so you can have the Focal Ratio to determine exposure times.
Oh, some people buy micro drill bits from Amazon and report accurate sized pinholes that way.
Amazing! Any one knows where can I find the math behind the pinhole cameras? I want to make my own designs, not the DIY you fin all over the internet.
good video, what app are you using?
