Shooting a HDR tintype with a super fast lens (and get them on Ebay)

When shooting wet plates, you deal with a very light insensitive process (about iso 0.5). So most wet plate artists wants to get their hand on a fast lens. Wolfgang, a former participant of my wet plate workshop got his hand on a very fast lens and sent it over to me. For the first time, you can get the plates from this project on eBay, starting from 1 Euro – http://ebay.mhaustria.com

Wolfgang, an Austrian based photographer who made this video possible – thanks a lot!

This Delta HD-6C ML lens is pretty huge and was used in vintage HD protectors many years ago. If you want to know more about this kind of lenses, check this blog post: blog.markus-hofstaetter.at/2023/03/shooting-an-ultra-fast-lens-140mm-f1-with-an-ultra-large-format-camera/

Here you can see how big this monster (a Delta HD-6C ml) is compared to a 35mm film canister. At the bottom you can see my self designed lens mount that I printed. A “very professional” 😉 solution.
A professional lens mount needs a “professional” lens support. For that I used plate holders and other stuff that was laying around in my studio. I looks a little bit like a Frankenstein monster build. But it grew on my and I like it that way.
The dreamy outcome with this wonderful bokeh makes it to my new Bokeh Monster

See the full transformation in my video

The yellow part of the flower absorbs a lot of UV light and thats the reason it appears dark when I exposed the plate normally. Thats why I did this series of 4 different exposures. I think every single one of them has something special in it. Just for fun, I created a digital HDR image out of them

Silver and light. Four exposures that are very different.
My digital HDR conversion of the tintypes. Next time I will try a combination of glas and metal.
I love this one a lot and will have a hard time to let it go on Ebay
If you hold this 18x24cm tintype in your hand, you can see the sling of all the little silver particles. This plate of this series will go to one of my Patreon supporters. Join here, if you want to be part of the raffle as well, join my supporters here: http://patreon.mhaustria.com
This lens has a razor sharp depth of field and therefore it’s not easy to handle. But if you get it under your control, you can archive unique and very dreamy results. I look forward to use it again.

    Shooting an ultra fast lens (140mm F1.0) with an ultra large format camera

    In short words “this lens is something else”. It’s extremely fast, huge and has a strange focus distance. It was used in Sony CRT Projectors from 1997. I bought it some years ago from a very interesting guy. He had so many more great stuff in his shop and I regret that I did not buy more. It took me some time to find the right opportunity to use that lens. But I think it was worth the waiting. I am glad my friend and former workshop participant Alois Stingl came over with is wonderful ultra large format camera.

    Before I could use it, it needed some cleaning, I used a cloth that was soaked with water and just put it on the lens without wiping to avoid more scratches.

    with some patience I could clean it.

    I measured the lens at infinity to calculate the F-Stop. I measured 135mm and the front element was 145mm That is about a F0.9 lens. But a document I found on the internet told me its more an F 1.0 lens. Still crazy fast.

    You can see here how short the focusing distance is. That makes it hard to focus un an ultra large format camera.

    When I saw the yellow coating on the front element of the lens, I thought about Mathieu Stern’s video about radioactive lenses. If it really is made of Thorium, it is indeed radioactive, but only for a very small amount. Watch Mathieu’s video to learn more about this Material

    Thorium was used to get more light into the lenses back then.

    Because the lens is very fast it is still dangerous. If it focuses the sun on something, it will start to burn immediately. That’s the reason you should not put the lens near a window and always put a lens cap on it.

    In the video I will show you how easy you can start a fire with that lens

    I thought it would be interesting to calculate the crop factor of an 40x50cm ultra large format camera. If you use the common formula to calculate crop factors you will see that this plate size has a crop factor of 0.0067 compared to a full frame sensor. With that you also can calculate the comparable depth of field F-Stop. This would also be F 0.067 compared to F 1.0 on a full frame camera. When I tried to focus on the ground glass, I could barley find something in focus. Thats why you see me focusing for a very long time.

    it took quite some time to focus with this very fast lens.
    I think this shows pretty well how sensor and plate sizes compare

    But there is more. a 140mm lens is a tele lens on a full frame camera, but it’s a wide angle lens on an ultra large format camera. This is because of the bigger plate size of the ULF camera. listen to my full explanation in the video.

    My drawing shows in a simple way that the subject needs to be farer away from a full frame sensor the get the same angle of view as the close setup of the ULF camera.

    To “connect” the lens to the camera, I designed and printed a basic flange in Tinkercad. It needed some pool line and tape, but eventually it worked out.

    I think Tinkercad is one of the most yeas to use tools for 3D printing.
    a very basic part, but incredible helpful
    No screws, just tape, pool liner and my 3d print. Sounds funny, but worked wonderfully

    The next issue was the fact that my darkroom was not made for 40x50cm plates. only for 30x40cm ones. After some tests with smaller plates, we only had one cup of developer left. Beside that, everything starts to get unpleasantly expensive if you pour on plates with this size. So my goal was to make it work with only one attempt. I did some dry runs to get comfortable with everything. Not only the dark room work was something I had to prepare for, but also the camera. These old beauties all have some quirks. Besides that, Alois made a beautiful plate holder by himself. These holder needed also some special attention. But as explained in the video, I love these challenges. It makes the result at the end even more sweet.

    To calculate the strobe power I needed, I used my wet plate strobe calculator that I created for my Patreon supporters. Since I made it, I use it all the time for myself, because it makes life much easier with the wet plate process. If you are a fan of analog photography and the wet plate process, have a look at our wet plate conversation magazine on Flipboard. Besides many great stories about our favourite process, you’ll wind there also work from other wet plate artists.

    I really like how this portrait turned out. As expected it is very abstract because of the F-Stop and the wide angle lens.Here you can see again how huge that tintype is.

    But this is not the end, because of some kind of funny coincidence, a former workshop participant sent me a very similar lens over. I am thinking to do a still life plate with that one. What do you guys think?

    Two very similar lenses. Funny how sometimes things turn out.

    But there is more, I got also a very tiny lens. I guess I need to build a camera for this one

    A full functional lens in the size of a thumb. I haven’t seen such a thing before. What a cutie.

    I hope you enjoyed that journey. It took me a long time to finish everything, but I am again glad that I worked through it.

    Darkroom Home Automations

    Even I am an analog guy, I am not shy to bring new technologies to my darkroom. With the wet collodion process I always try to avoid touching anything unnecessarily. So I build some home automations to assist me with that. Every analog photographer knows the struggle. You work in your darkroom and in this very moment you don’t want to be disturbed. Just imagine, somebody opening the door and your film/paper/plate is exposed to light. For sure, you just can mount a red light on the entrance door and you are safe. But in my case (and I am pretty sure I am not the only one), I have a main entrance to the darkroom and two other doors. One door leads to my studio and the other door to my pouring room. That means if any of these doors are open, it is safe to enter the darkroom. If I just would have a red light on the main entrance door, it would be hard to understand for my workshop participants or sitters if it is safe to enter. Thats the reason I build a solution for that with Apple Homekit (you for sure can build it also with Google/Alex or anything else). But there is more. We all have running water in our Darkrooms. And I think some people will have a water detector. But what if you have to wash something with running water and are not in your darkroom all the time? I used Homekit for that as well. I show you also a solution for measuring time without touching anything. This may be very specific to the wet collodion process, but maybe it may be helpful for others as well. The last topic is about how I feel more safe with my 3D printer.

    I looked also for Google/Alexa devices, but most of them are working with wifi instead of low power bluetooth or thread. So I am not sure if I want to recommend any of these, please let me know which ones work great and I post them here.

    3D Printing for (analog) Photographers – Artillery Sidewinder X2 faild edition

    Because I got asked a lot about 3D printing, I did this short introduction into it, or like I call it: let the fails continue.
    It’s about the Artillery Sidewinder X2 and some broken parts. Very different to all these unboxing where everything works out of the box. I will show you also why a 3D printer can be very cool for photographers. Here you can find all tools I use for wet plate, 3D printing and filming: http://list.mhaustria.com

    Never give up – a 300mm Zeiss Tessar project with lots of fails

    In todays video I documented my fails (wood working and 3d printing with sidewinder x1 – also building plate change of the sidewinder x1) while I tried to mount my new lens on my camera. I got this lens, because I do more and more wet plate family portraits and for that I wanted a sharp affordable lens. Normally I would show you guys how I did a family wet plate portrait(its online now, scroll down for the second part). But I couldn’t do it, because of our lockdowns. So I worked on a self portrait. To make this easier, I turned my studio into a darkroom, so I can move without getting a ghosty image on the plate. Because I put metal sheets into the ceiling during my studio renovation, I could mount the red light easily with magnets. To see the whole story, watch the video 🙂

    Shooting Wet Plate Portraits with an affordable Large Format Bokeh Monster

    I should stop calling these “Short Projects” short projects. It didn’t take that long, but still longer as expected.
    After I bought it at the Camera Obscura Festival
    But I still think if you are looking for a affordable large format wet plate camera, you should have a look at the Mentor camera brand. Most of them are build like a tank (Remember, I got another Mentor too, where I did double exposures with: https://youtu.be/y0ccDnXw9xE) and easy to repair. The cool thing of this camera is the curtain shutter and strobe connector. It has also all movements you can imagine, great for architecture, product (or food) photography.
    For the wet plate process, you want to look for a fast lens, but these are mostly pretty expensive. Thats why projection lenses are a good options, but most of them are triplet designs – but there are others too, like the Leitz Hektor 200mm F 2.5 that covers 13x18cm plates in portrait distance easily and has 4 glass elements instead of the classic triplets. be aware that the depth of field is razor thin on that lens. I have a second one for sale here http://gear.mhaustria.com with other camera gear I only use very rarely. So I would be happy if this finds someone who uses it again. I just collected to much gear….
    In the video, I show you how I repair all the little blemishes of the camera and add two Lenses to it. I even build two lens plateadapters. One to mount lenses from my Century camera to the Mentor and one to mount Linhof Lenses to the Century camera. Check my Thingverse too, I will post some of them there if I am happy with them. . The more I get comfortable with my 3D printer the more I use it, that reflects also in this project. Even some prints take pretty long (my longest one was 16 hours), it saves me lots of time, because I can do different things in-between. And some of the designs would have been much harder to create with traditional wood/metal working.
    I really like how the camera, lens plates and wet plate holder turned out. This will be used on many during my workshops (for English ones contact me here)in the future And I am also very happy that Tanja of https://www.unikat.pictures/ helped me out to model for me. Thanks a lot!

    How to create Waterhouse stops for antique lenses

    Large format photographers who work with antique Petzval lenses know the hassle. You get a pretty new brass lens, but there are no Waterhouse stops included. “Hey I don’t care, I shoot anyways wide open all the time” some might say. With some, I also include me. But then you find yourself on a very sunny day and struggle with doing a very quick exposure, like here https://youtu.be/nStEK3zV5tA?t=438 (and you will end up anyways with an overexposed image, even with the not so light sensitive wet plate process). Oh yes, and there is also the creative point of stopping down your lens – but wait, who really does that if you can have a dreamy, swirly Petzval bokeh, right? 🙂 Just kidding, I would have needed these Waterhouse stop more often than I thought of. That’s why I finally 3D printed them (there is also another option) and did a tutorial for you guys, so you can make them too without having to much trouble. At the end I also decided to make carrying case for them, to have them in a safe place. If you don’t want to make them by yourself, check out http://gear.mhaustria.com – where I will make them for you (Dallmeyer 2B and 3b Waterhouse stops are available right now, but you can contact me here https://www.markus-hofstaetter.at/pages/kontakt/ and we will figure something out for your lens).

    Touchable Bokeh – 3D Printed Wet Plates

    have you ever felt a photograph? I guess not, so maybe my latest project about 3D printed wet plates will change that.

    These beautiful prints (litophane) took a pretty long time to finish. My printer was working on them for 17 hours per print to make them as beautiful as possible. And that does not include all the fails, the search for the right filament and to find the right settings. But I am so happy that it worked out. If you want to have one of these beautiful artworks for yourself, check out my Ebay store http://ebay.mhaustria.com or contact me directly here.
