Louis Daguerre had a invention & business connection with Nicéphore Niépce, the man who is credited with the 1st photograph in the late 1820's. It was called the latent image back then because the word Photography was not invented until the late 1830's. Louis Daguerre & Nicéphore Niépce shared the same optics/lens maker (Charles Chevalier) who after learning about Louis' ambitions with trying to create a successful latent image, connected him with Louis Daguerre. There are postal letters between the two, & Nicéphore Niépce's process with the latent image played an encouraging role in Louis Daguerre's Daguerrerotype.

I was wondering if you'd ever cover some of this stuff, it's really neat to see as a collodion hobbyist and occasional daguerreotypist. Just a few small notes about daguerreotypes: 1. You don't actually *need* to develop a daguerreotype to create an image. The silver halides will eventually produce an image if you expose them long enough, but the big problem with that, aside from exposure time, is that the sensitized plate actually turns *black* in the exposed areas, which means that you would end up with a negative image that could only be viewed as such by reflecting a white background in the plate. The beauty of mercury development is that not only does it bring out a latent image that wasn't visible to the naked eye, but it replaces the darkened silver halides with a white amalgamation of mercury and silver, which is the reason you're able to view the plate as a positive. 2. Generally a sixth plate daguerreotype wouldn't be one sensitized plate cut up into six pieces (although there were some cameras that could project multiple identical images onto a single plate to be cut up later), it was just a popular plate size about 1/6th of a full plate, which is a size that Daguerre somewhat arbitrarily picked to give an edge to the French lens-making industry (the blanks required to make a lens that would cover that size were more readily available in France than England). In practice a whole plate was extraordinarily expensive (even today it would cost me a little under $200 to get a clad silver plate in that size) so they were rarely used. The first successful Daguerreotype portraits were made with mirror cameras that could only create a clean image about the size of a 1/6th plate, so between that momentum and the fact that they were just a much more affordable size it ended up becoming the most common portrait size. 3. The replacement of daguerrotypes with collodion photographs has less to do with the ease of viewing and a lot more to do with the practicality and expense of creating a Daguerreotype. Collodion allows much faster exposure times which helps with portraiture, but most importantly it's much, much less expensive. To make a daguerreotype you need an entire plate clad in metallic silver. To make an ambrotype or tintype you use a silver nitrate bath which can be reused for a great many plates before replenishing, because only an infinitesimal amount of silver actually makes it onto the much cheaper substrate. It's also worth mentioning that collodion allowed the creation of glass negatives, which could be printed to make as many identical copies as you want For anyone interested in the origins of photography, Mike Robinson's dissertation on the development of the daguerreotype process is really fascinating: centurydarkroom.com/s/Robinson_Dissertation_TMAD_sm-lsmh.pdf

@@MrTridac Video since the 1930's was always electronic AFAIK? :) Maybe video camera tubes were capable of pictures of the similar quality as 16mm and 35mm film, but with the standards for broadcast television set as they were, there was no point to hypothetically record at higher line counts? I dunno. In the field, film was used instead of videotape for recording television serials well into the 1970's or 1980's IIRC (you'd see the difference when the protagonists went from studio to location), so I don't know if recording on location with video was impractical.

[@the_undead]

@@TassieLorenzo you could record on location shoots with video equipment that was not film cameras the if you was that those cameras were very much not small things so if you wanted to be able to bring the camera with you to record a walking actor then good luck have fun.

Wow, just seeing that can at 35:09 sent me instantly back to junior high school (several decades ago.) That process is so simple that our yearbook photography staff - 13 to 15 year olds - developed our own black and white photos in a darkroom in the basement of the school. And now that I'm thinking of it, I can recall the particular smell of the chemicals involved. (I also learned to jimmy the simple lock on the darkroom door with a knife and a library card, but that's another story.) The other part that I found a personal connection to was the original Kodak camera, a (leather bound) cardboard camera that you sent in to have developed. When I got married in 1998, we bought a bunch of cardboard cameras for the reception, and left them on all of the tables for our guests' use. They then deposited them on a table as they left, and we took them back to CVS (a US drug store chain that also sold the cameras) to be developed. The only part that differed was that we didn't get the cameras themselves back. I never realized that the basic idea was already about 100 years old at that time!

I recently inherited a collection of my grandfather's negatives from about 1912-1950. A mix of 116/120/127 and some intermediate sizes that don't seem to fit any standards. Amazing to see images of my family from a century ago, along with the land where my sister still lives. Of course I had to buy a new scanner to handle medium format negatives, but it was worth it!

[@dawnparsonage5386]

Very nicely described, but let’s not forget Fox Talbot the inventor of the negative to positive process in 1839. Daguerre got there first with announcing a useable process, but Talbot with his Calotype was more like the ‘film’ we know now - allowing you to make multiple prints from one negative (be it a paper negative). But you may be coming this in the next film. Loving your work! VERY excited you’re covering photography things!

I learned more from this video than I did the whole year I learned photography at school. All they taught us was art but using the camera instead of a paint brush, they didn't go into how the camera worked. Well done sir!

[@russlehman2070]

During my childhood, on a trip to Yellowstone, my Mom, using a roll film camera, made an accidental double exposure, and ended up with a picture that appeared to be a bear submerged in the bottom of a hot spring pool. Usually though, double exposures were not that entertaining. With this type of camera, the best practice was to advance to the next frame as soon as you had taken a picture. In any event, you needed to be consistent in your procedure, so that you didn't accidentally double expose, or advance twice and end up with a blank frame.

[@twelvecatsinatrenchcoat]

Ha, I’m imagining my mom trying to remember to roll the footage every time. She once recorded half of Europe’s sidewalks cause she mixed up recording with not recording. If she used a Kodak like that, every photo would be a double/triple/septuple exposure.

@@phydeux100 year old cameras are often higher resolution than modern pro digital cameras. But the brownie is not one of those cameras. It's literally the early 20th century version of one of those disposable plastic cameras you can still get at a drugstore. It's higher quality than the modern disposables, but still not great.

[@phydeux]

@@lobsterbark - No doubt. I don't have anything against film cameras. In fact, they can do a lot more than digital in the right hands. I'm just saying the early brownies and such were one step above prototype stage. So seeing a hipster give it rave reviews is like seeing a 5 star Yelp review for a cow pat.

[@lobsterbark]

@@phydeux A brownie brute forces image quality by having a massive negative. I'd say the resolution is similar to most mid-low-end phone cameras these days. When you consider that people rarely complain that their phone camera is too low resolution, and that brownies have a distinct interesting look to them, it's not surprising people might like them. They make excellent contact prints, which is how they were originally intended to be used.

[@esalehtismaki]

Daguerrotypes really look amazing. All development after that made the process easier and cheaper (and less deadly) and viewing less finicky, but sacrificed something in the quality. Even today's digital images can't compete in the number of shades of grey and resolution, at leat on the actual media, forgetting optics. I envy your Ektachrome shirt.

This episode was excellent! I remember I made my first "camera" when I was a kid. Back then, I was a lot smarter than I am now. By chance, I figured out that if you hold a magnifying glass in front of a light source, you could project an image of the lamp or what ever it was, a certain distance behind the magnifying glass. So, I made a hole in a box, and taped the magnifying glass in front of the hole. Directly behind this, I used stove paper (semi transparent paper you put you pizza on when cooking it in the oven. Don't know what it's called in English) as the viewing area. My dad then recognized what I had made - a basic camera obscura. He said that I could put a mirror at 45 degrees in there, and project the image 90 degrees upwards. Now I had sort of the same camera as your Agfa, only without the possibility to take pictures, of course. I had plans to use film or something else in the back, and move the mirror down to take a picture - but being a stupid kid, that plan never came into fruition. Thanks for the walk down memory lane=)

[@sglynnphoto]

As a modern tintype photographer this was a fantastic summary! Fun additional info viewers may find interesting: Tintypes in particular take about 1.5 hours from coating the plate to drying the varnish. Exposure times are usually 2-10 seconds with natural light or about 6000w/s of strobe at 3-5 ft is usually enough for a good exposure. Because it’s a UV sensitive process so colors appear differently such as reds getting much darker, blues getting much lighter (wood looks black, blue jeans look almost white, freckles look very distinct, blue eyes look almost completely white). Tattoos often almost disappear or sometimes so disappear because they’re under the layers of skin that reject UV light. It’s a laborious process that takes a ton of skill,practice, and tons of patience to get consistent long term results. Those that do it well have probably spent hundreds of thousands of hours practicing and studying! It’s such a fun and almost magical process to experience first hand if you ever find the opportunity.
