Hey! Just a head’s up, you aren’t even getting the best possible results here, you’re using film with much too course a grain. You do mention that however you also seem to maybe be under the impression that you can’t get film better suited for the job. You can, actually, look for repackaged microfilm. Adox CMS 20 II is a common one, however you can get an even more fine grain film called MZ-3 from a Ukrainian company called Astrum. It’s ISO 1-3, and has insane contrast. If developed properly it will probably out-resolve your microscope. If you’re interested in seeing how far you can take this, I suggest checking it out!

Another microform (the most general term) is the microcard, which, like microfiche has a grid of several page images (and it is similar in size and content to the microfiche), but it is an opaque, positive image, like a glossy photographic print, rather than a transparency. It's more or less what you would get by printing a negative microfiche on ordinary black-and-white photographic print paper. They were never as popular as microfilm (the earliest) or microfiche, and it could be a bit of a pain to find a reader. Nowadays I suppose a high-resolution flatbed scanner could be used to read them.

Old photography rule - f/8 and be there. Expand on this a bit: if you're in a hurry f/8 will usually be sharp enough if you focus well. Your glass may be its sharpest a bit more open or a bit more stopped down than this. Fast glass is typically at its best a stop or two down from max (largest, widest, smallest number) aperture. So like a f/2.8 lens might be happiest at f/4 or perhaps f/5.6. Kit glass, cheap glass, etc you'll usually end up around f/8. Much beyond that and diffraction becomes a problem quite fast.
@xander1052
2 ай бұрын
An old rule of thumb is the middle aperture tends to be sharpest, so for instance on my big 300mm f/5.6 it should be sharpest around f/11. the f/8 and be there is genuinely pretty accurate for mid speed lenses though as their middle aperture usually is exactly f/8.
@zackl3094

@@xander1052 it might be sharpest then, but you've lost so much light and gained so much diffraction it's not going to be all that useful at the end of the day, especially for something like this at the highest end of what the system can resolve. When you're trying to squeak out max resolution, you need good light, good focus, and your lens to be at its best aperture for the task at hand, which may not always be the "sharpest" - it's probably good enough. There's focal length and depth of field considerations to be made as well. It's not as simple as f/8 and be there, but that will definitely get you close enough for most stuff. For specialty situations like this, there's a lot more to it. It's why string is useful for fixed focus cameras. It's "calibrated" so that you could hold it from the right distance to guarantee critical focus. The rest was basically decided for you in hardware, other than the lighting conditions.

I did some CR when I was working in the city close to the office. Even today at the facility I work at, I'll occasionally require the radiographers to use high emulsion film where CR just doesn't capture the sensitivity for whatever reason, but they use 95+% CR here. DR is still running into limitations at a facility with high temperature piping well above the ground. You can drop and break a film or CR cassette, or melt/warp the screen without it being the end of the world. 14x17 DR cassettes on the other hand are very costly.

In fact, it's possible to create the microdots without a camera, as long as you have photographic film (which you can purchase at any shop). What they would do is create, essentially, a pinhole camera with normal household materials (carboard boxes etc) and use it in a dark room, flip the lights on for a second or two, and then cut the part of the film that had photographed the document and put it eg. under a stamp. All these materials for the pinhole camera are easily disposed of, and consist of materials that are not suspicious. No government officials would find anything suspicious in that apartment or on the spy himself, even if they searched.

Hello! I've done a lot of developing, mostly colour c41 though so the chemistry is a little different. A few tips I have : Make sure everything very dry before putting it into the dark bag. Humidity and water make the film super sticky and hard to wind onto the spools Developer is fine to reuse! Every two or three uses, just increase your development time, I've used mine up to 15 times before swapping it out. To avoid any splotches it's helpful to do a clean water rinse between each stage of development, this also helps the chemistry last a few more uses. Particularly with colour development, temperature control is very important! I do all my development in a water bath held at the appropriate temperatures, this varies for each stage of development. Lastly, make sure you squeegee your film after developing, it avoids any water spots and it's also super satisfying. Love the channel!
@alfepalfe
2 ай бұрын
As for dryness, yes with plastic reels. Steel reels can be loaded soaking wet but cheap steel reels tend to be terrible and nice steel reels (Hewes brand) are expensive. Developer is usually fine for approximately 10 films per liter of stock solution. He is however using "blazinal" a varaint of rodinal which is a one-shot developer. As for temperature control, modern b&w film is remarkably tolerant of abuse. Far too hot and they may be a bit overdeveloped but other than that it should be fine. If I recall correctly the problem of reticulation requires something crazy like a 50°C temperature change during development with modern film. As for water spots, several methods are in use. Squeegees are fine but you need to be very careful that they're completely clean as any particles on it can scratch the film along the length. Personally I just wash the film using the ilford was method, then fill the tank up with destilled water and just 2 or 3 drops of wetting agent before hanging to dry. That usually gets it spotless.

This video is absolutely fantastic! The way you briefly went from explaining film technology, to demonstrating how it gets used to shrink down images, and then incorporating Holographic Optical Elements! I actually didn't know you could do that at the scale where a standard negative film (and not a special microfilm, holographic film, etc) is able to capture. I love how you demonstrated so many examples of it, too! There seems to be not many videos going over this with so much to show, except for Huygens Optics incredible videos. Some things I would add is besides Fuji's HR microfilms, there are a lot of other silver-based materials you can use such as ADOX CMS 20 is still sold, their HR-50 seems like a good candidate as well, Rollei RPX 25, and you could probably investigate many holographic plates that are sold. Some of these microfilms can store up to 800 cycles/mm or more, but holographic materials can easily achieve 2000, 5000, and some close to 10000. The only problem is they're for the express purpose of recording interference patterns of coherent light, not normal optical images which start to become diffraction limited far before those figures (in Vis). Another fun thing was the Lippmann process where a special ultra-fine emulsion is used to photograph objects, but using a mirrored surface behind it the standing wave patterns of light interfering with itself _in the depth of the emulsion_ which effectively records the wavelengths of light; the color. It's a dyeless color process done through the light interfering with itself! And it was made in the 1890s and you can do it yourself as well! It's too cool! So, anyway, maybe I'm just "uhm ackshually"-ing the part about needing to immediately jump to something that isn't silver based lol. Especially with how difficult it might be to source a good photoresist. There's a lot of possibilities in silver halides! To get the sharpest image you need to balance your lens aberrations being curtailed by stopping the lens down to a smaller aperture versus diffraction which increases as the aperture gets smaller. Some well very well-corrected lenses can do this just a stop or two below wide-open, but for many lenses 5.6, 8, or 11 will be the sweet spots for reducing aberrations. Regarding your development setup, it's really nice! Glass seems to store the chemicals a lot better without needing to resort to crazy things like topping the bottle off with butane or something. And I just tried developing without gloves for the first time a few days ago... yeah I totally agree with you there, my fingers had such a weird smell on them the rest of the day. For developer, highly-diluted stuff is almost always considered "one-shot". You toss it after you use it. Like when people dilute Rodinal 100 times. But with dilutions that are a lot less you totally can, I just don't know the details about how to do replenishing "right". I might be overthinking it though, usually you just give it more time. I'm so excited to see what you do next!! This was so awesome!!

Also many holography resources have good information on Lippmann because it shares the space, both holography and the Lippmann process require ultra fine emulsions because they capture interference patterns! In general, making your own emulsions is an infinitely deep science on its own, considering what you can do by varying temperatures, times, layers, which halides, concentrations, sensitizers, etc. For making these microdots, CMS 20 is probably all you need but I imagine you can play with a whole bunch of variables and cook up your own film with cool properties!

In the early 1970's I was employed by Microform Data Systems. The product was ultra-microfilm readers and media. This was on the cusp of the rise of digital information systems. The media was strips of 35mm film with six frames. Each frame held hundreds of pages of text reduced in size by a factor of 200 times. About ten strips fit into a cassette that allowed any strip to be fed into the reader. A large installation was purchased by General Telephone (LA) for their directory information operators. An array of readers was connected to a Digital Equipment Corporation PDP8 mini-computer. The computer held the programming to control the readers to select the correct strip, frame and exact page location on the frame for a given name input by the operator instead of thumbing through a mound of telephone directories. I worked there for three years but even then it was obvious to me that any such system would be replaced by entirely digital data systems. Even so. microfilm is still one of the most durable types of information storage.

Just a few pedantic comments. Daguerrotypes were indeed made on metal plates, but it was polished copper that was then coated with silver. Solid silver plates would be way too expensive. The halide in your film would be silver bromide, iodide and chloride were used back in the day when collodion emulsions and POP prints were widespread. The development process doesn't darken silver crystals, the photon of light creates what's known as development center within the structure of silver bromide crystal, developer reduces the bromide to metalic silver, the grains altered by light are converted first. If you'd left the film in the developer for long enough, all of the halide would turn into silver. Have fun! The traditional photography spawned literally hundreds of processes, it's a bottomless pit for both time and money 😅

Photolab technician for over 10 years here. Yes the chemicals can be reused several, several, several times (the loss of its strength is minimal). But it will become saturated by silver at a point, and you'll start seeing a difference in contrast in the developed film as it does. For plain B&W with no shades of grey, you may want to overdevelop it (the 1st part of the process) for a little more time to get stronger blacks and whites. DO NOT THROW IT DOWN THE DRAIN. Sediment, decantation and reduction... And recover all that precious silver.

I'll second this. I'm a photographer who worked for a commercial shooter before digital. He had a darkroom and the developer was in this big stainless tank, and was over ten years old! We would replenish it occasionally. He claimed that new developer wouldn't have that "magic" smooth look until it had been replenished a few times. There was likely hundreds of dollars worth of silver sloshing around in the sludge at the bottom :)

Hi! I do a lot of black and white development. When it comes to development with Rodinal (blazinal is just another name for Rodinal) the easiest way is a 1:100 dilution, for an hour, with some slight agitation at the beginning and then at 30 minutes. This will develop near perfectly nearly every time. You also dont need to use stop bath, as a water wash is perfectly adequate if you fix immediately. Blazinal is a one shot developer and should not be reused, though at your dilutions you may get away with it. You can however reuse fixer basically until it stops working, to test if its good you can just through your film leader into the fixer and see how long it takes to go clear, if its too long just make a new batch. I hope some of this info helps

10:58 this is actually a common beginner photography enthusiast pitfall. A given lens is not guaranteed to be sharpest when wide open - in almost all cases it's not. The rule of thumb is two stops above maximum aperture is sharpest. In your case it should be around F3.4. That being said, an ancient consumer lens is probably so imperfect that it doesn't make a huge difference in this case
@alfepalfe

I believe he meant fully stopped down, not wide open, might degrade sharpness a little bit but with PAN-F in this case that should still out-resolve the film or at least get reasonably close. It will also ensure that even if you miss focus a tiny bit which is easy since you're trying to make the image a tiny part of the frame, it will likely still be well within the depth of field. This is however still important as he said in an E-mail that he had ordered some ADOX CMS 20 II. That will absolutely out-resolve the lens so for that it is important.

If your optics has known aberration problems, you can reduce the optics problems by reducing the aperture (and, of course, correspondingly increasing the exposure time). The smaller the aperture, the more of the peripheral parts of the objective's light path are effectively blocked, meaning optical imperfections in these parts will not matter for the final result.
@wellscampbell9858

That works, but has a limit. The aperture's edges are making a diffraction pattern, and when the aperture is small enough, the diffraction begins to dominate, and smaller apertures actually reduce sharpness and contrast. For typical lenses, the sweet spot is around f/8 to f/11.

If you want something even finer-trained then PanF+, Adox CMS 20 II is as fine as consumer films come. The exact sharpness apparently exceeds testing equipment. Kodak 2383 is an internegative or interpositive, I forget which, that I shot at 1.5 ISO and it's the only stock I've ever used that I can't see grain clumps on with either a grain focuser or a high-res macro lens and live view enlargement. Also, the Series E 50mm is a very good lens, but if you want to go crazy with some even better options for this project, I could make a few suggestions.

Small caution about PANF: It notoriously has poor image retention properties, be sure to develop images taken on it within a month or so. I'd be curious to see what Delta 100 pull-processed at 50 looks like, though that usually mostly affects contrast, not accentuate. XP2 Super may be interesting, since it's a C41-process film that relies on dye to make the final image. FPP Dracula (aka Svema FN-64) is a wonderfully sharp and high-contrast film with a very clear base. For the lens: while shooting wide-open has its benefits, most lenses are not at their sharpest wide open. If sharpness is paramount, using a lens a stop or two down from wide open is advisable.

With black and white film, the silver halide Chrystals get reduced to metallic silver in the developing process. The fixing removes all the remaining halidechrytals that remain. What you are left with is basically little dots of silver that make up your image. The developer is in some cases reusable, check the manufacturer's data sheet (there's always a data sheet). There are special high resolution film / developer combinations. I would suggest to look into that. Adox CMS 20 pro and so on. (as others have already commended). Resolution on the film is a product of: Developer - Film - Optic - Steadiness When taking an image with your consumer photo optic, and you want to achieve maximum resolution, you should use f,5.6 - f8. An aperture smaller will decrease your resolution, and a more open one will also decrease the resolution. Reusing the developer could decrease image quality. The developer dilution will also affect your image resolution in many cases. Try to get dedicated "high resolution" films and developers, use your lens at its sweet spot and keep your camera very steady. All the best!

Yes, the developer can be reused, but each time it is used, it accumulates some bromide in the solution. This can behave in weird ways with the next batch of film, and if you're using it to send classified messages, you would probably not reuse the solution. But, as I think about it, the bromide actually could give you better clarity after it reaches its plateau level because it could reduce grain in the image because it decreases the film speed as its level increases, up to a full stop. As bromide increases, though, the images become darker because more light is needed.

Another couple suggestions. Most commercial lenses are sharpest around f/8 or f/5.6. Opening up or stopping down from there will typically lose sharpness of edges. Also, you might want to track down a “process camera”, basically a specialized camera meant to copy things to microfilm or for use in printing. They’re fairly cheap because they aren’t useful for art photography, and lot of schools and libraries had them and are getting rid of them. Also, you should check out the Adox CMS films, which are basically high contrast copy film. The Film Photography Project also has “Hi-Fi” film, which was originally meant for optical sound recording and would do very well for your purposes. Also also, depending of what you’re photographing, use a red filter on the lens to boost contrast. It’ll knock off about three stops of exposure, but with panchromatic film it’ll render the image in almost pure black or white.

Blazinal is a rebranded version of Rodinal (probably the oldest and most ubiquitous developer still used today) and its generally not a good developer to use more than once, its sometimes called a "one-shot" developer meaning you use it once and toss it. I personally use Kodak Xtol which is excellent for re-use and has a great price-per-roll especially when using the "replenishment" method. However, for your use I would not recomment Xtol because its a "solvent developer" meaning it dissolves the sharp edges of the silver-halide grains and generally smooths out the grain at the cost of some sharpness, rodinal is probably the right choice for what you're using it for because it has exceptionally high sharpness, but you do have the side effect of very strong grain, but like you said you can get finer grain with lower-iso films.

The highest resolving photographic film in the world is Adox CMS 20. As a 35mm film, it out resolves any lense ever made at 800 lines per millimeter, resulting in a theoretical resolution of 500MP. According to Adox you can print a 35mm piece of film up to 2.5m without rendering any grain. The trick is that it's a relatively slow film at around ISO 20 if using their dedicated developer. In the case of creating microdots, that's not an issue though. Whilst Ilford Pan F 50 is a great film and fine grained, there are definitely even finer grained films available. Regarding Blazenol, it's basically a rebranded Rodinal which is a very old recipe (130+ years old). Whilst it renders a sharp image by accuntuating the edge of the silver halide crystals, it has the downside of enhancing the grain. I'm not sure whether this results in more readable text, but two other developers which could be tried are Ilford ID 11 (or the equavalent Kodak D76) as well as Kodak XTOL. XTOL is a developer which disolves the grain somewhat, resulting in a smoother image than with Blazenol but might be a little less sharp around the edges of the text. ID 11 should be a middle ground between the two.
