Very cool project! As a photographer who has never built his own camera (but who loves playing with antique lenses), I have a couple of suggestions for your consideration: 1. Just as how with a pinhole camera, a smaller pinhole will result in a sharper, but dimmer image- you may consider adding an aperture or a mask to act like an aperture immediately behind the lens to force the light through a more narrow opening. This could result in a sharper focus. It should also make the edges of the image more in focus relative to the center. This increase in sharpness is more than what's offered by the expanded depth of field. It's an increase in maximum sharpness, and I believe it's due to a reduced angle of incidence. Which leads me to the next item... 2. If you ever go to remake your lenses, you might try to reduce your angle of incidence by reducing your curvature, and instead rely on the distance between the focal elements to get the light to where you want it to go rather than extreme curvature. The greater the angle of incidence between the lens' surfaces, the more critical a perfect polish and flawless glass becomes. And, in general, the more difficulty you will have in getting a sharp focus- particularly around the edges. One of the reason that modern lenses have so many elements is because it's an attempt to minimize the angle that the light is bending with each surface plane it intersects while still having a compact lens. Instead of a few planes with sharp bends, you get more planes with slight bends. Anyways, awesome video!! I look forward to seeing more!

Old cameras used very bright light sources. In the 1960s, a hand held motion picture camera came with an array of very hot light bulbs.

@mightisright Жыл бұрын

Yes, because usable film stocks were far less sensitive than current digital sensors. The images we see now (especially at night) were impossible to create without arrays of high lumen incandescent bulbs, using far more energy and putting out far more heat than the LED-based lights available today. The most sensitive film available was 3 or 4 stops above 100 ISO and produced large grain, ugly images mostly suitable for science experiments. While there is a limit to how much light a lens can transmit, the digital revolution made up for that with sensors that make it possible to see nearly as well as a nocturnal animal.

Regarding the SD card corruption: next time make the SD card read-only once you have everything set up. A lot of people who run Pis for servers and things will keep the SD cards as read-only with just the OS and then use a USB drive (or other external harddrive) so the SD card can never get corrupted. Source control would also help. It sounded like you lost all of your code; I've struggled with that enough times that at this point I don't start a single project without setting up a GitHub repository.

Agreed, A while back after the recent fire he did a survey asking us what we would want etc. I remember commenting something very much like your comment, I think I said something about that with the reset because he's trying to do it linearly and "unlock" stuff , if he fails then it kinda haults video releases too. I also really liked the early days where he would remake stuff from scratch today, and show how much work goes into a normal sandwich (like $500). The 'show' is asking a question about can you rebuild society from scratch by one man, but often times they would prove no you can't. As Andy would get help from people who knew what they were doing. I remember a woman who used to help him with weaving/looming etc Which is great, it was like making a poignant statement that human civilisation was built by multiple people WORKING together. And Andy was more of a host talking to experts and educational. I understand the reason why he did the restart , but we lost a of potential/momentum. Becuase at the end of the day Andy is a regular dude and doesn't have the right skills for everything he's trying to do. Because of the reset he didn't even have an anvil, which made his other projects much more difficult. I've often compared this show to something like Mythbusters, and I think if Andy and the team did what they used to do where if the myth failed they would find out what it would take to make it work. So if we had andy try to make something and then fail, he then could bring in an 'expert' and find out how to make it. Which would show the value of the skills/knowledge that person and trade has. ---- TLDR: Agreed.

Important advice for anyone doing highly configured/customized Rasbian set ups, get it configured how you want and create an image file you can flash a new SD card with in the future so you can possibly save hours of time if the card corrupts in the future. If you are doing something tomorrow, image it the night before, maybe make a spare SD card so downtime is just how long it takes to reboot after a crash.

You know, having wood veneer would have come in really handy, for making the telescopic part for the lenses. So I think that one of the projects after calculating what electric motor you can use to equal the water rotating the waterwheel, and after testing multiple methods of power transmission and power conversion between torque and speed, should be making a machine for making veneer from a log (rotating it) or from a plank (shaving it like with a wood plane), and then using the veneer to make a book using charcoal for painting and a mixture of oil and wax for waterproofing the written paper and sealing the ink in place.

It would be interesting to buy manufactured equivalents of all the components, assemble them into an identical camera and take a picture with that to see what the theoretical maximum achievable quality is. That way you have a target to know how much better is possible and you're not striving for something that may not actually be feasible with your current configuration.

People have actually made really excellent pictures using scanners as ad-hoc pushbroom imagers. The resulting images generally have essentially flawless quality and a very specific aesthetic to them.

This was one of my favorite projects and I always felt mad about the broken lens. It is indeed a cool idea for this event for sure. I think the blurryness comes from the cristal structure of the glass lens itself. The light is bowed at some point through the lens and the image which actually can be captured by the sensor has gone through these crystal structures. BUT When you have binoculars and a blury image, you have the oportunity to move the lenses carefully by moving the diopter wheel until it is sharp. Maybe you have just to adjust the distance between lenses.

@BlackthorneSoundandCinema Жыл бұрын

I think that the image quality issue is more from the separate camera shooting the diffusion and fresnel rather than the lens itself. If you made a lens that was designed to project directly onto a 35mm sensor made the same way it would look completely different and far better.

@BBROPHOTO Жыл бұрын

Considering how large the front element is and how short the focal length is, that's going to one hecking fast lens! That likely is your issue with the resulting softness. Creating fast aperture, wide angle lenses is really really tricky. Narrowing the aperture down synthetically with an aperture mask or blades would help a lot, as it does in the real photography world. Look at how crappy some of the early fast lenses were and how big of a difference stopping down from F1.4 to F4 would be. Finally, your actual back focus might be off. Even if your lens is perfectly in focus with pristine optics, if the sensor is too close or too far away it won't reach critical focus and that'll be exacerbated by a fast aperture lens.

@sbcinema Жыл бұрын

I think I can help you there, as a photographer who works with old cameras, i know that a image that is projected onto a surface like the ground glass will never be really sharp, which is why it was removed from old cameras before the negative was inserted. It is best if the sensor is placed exactly where the glass was.

First off, great job. You've done what I have dreamt of doing for over a decade (making glass, and making a lens with it). I have also had plans to make a large format scanner back camera. I think a couple of your biggest issues is getting your image and/or sensor in the focal plane. When focusing on your ground glass, did you factor in the glass thickness? Also, you may have been able to bypass your "focusing screen" altogether by simply having the scanner's optics in your lens's focal plane. It should then be capturing the image coming straight out of the lens.

Well.. i haven't watched the video/s where you make the lens and glass, and i might be completely wrong here as well, but here's some thoughts as to why the images aren't as sharp as you might have hoped. 1: This one is certainly the thing i have the least amount of knowledge of. Maybe your glass isn't as smooth as it should? I mean you can polish it til you go through it and all, but is there's "large grains" in the glass itself then no amount of polishing will help as you only make those grain larger by magnifying them.. right? 2: Many have said this, but light is important. I would also suggest testing where your lens works at its best. While you can buy a lens that says 60mm-100mm its best performance might be at 80mm. 3: Maybe try moving the magnifying element further or closer to the outer glass if possible? You have probably thought of/tried these things already, but they are my surface thoughts nonetheless. Something that just hit me. The scanner part you use, isn't that supposed to magnify things that are really close to it? I know the glass helps the zoom part of the thing, but could that be the problem?

How about recording SOUND. The principal is so simple it's a wonder the Ancients didn't do it. If a disk or cylinder is too complex, a strip of metalic foil, pulled under the needle and wound on to a reel might work well too as an impression surface. A tin horn could amplify the sound of the needle vibrated diaphragm to play it and recording could be done by simply speaking into the horn as the metal strip is pulled under the needle.----- The recording needle and playback needle would need to be different though the former would have to plow a grove in the recording surface and the playback needle would have to be a bit duller to just RIDE the groove.
