Sad News, DPReview is closing its doors

Amazon is closing dpreview.com, I never thought such a standard in this industry will be gone in a few days. I put my thoughts in a video. This is frustrating for me, because such a great source of information soon is no more

    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.

    Preserving History – Renovating a 100 Year Old Camera – Bellow Edition

    My good old Century No.2 camera has about 100 years behind her. She still works great, but her bellow is leaking light. Thats why I needed to repair it. I thought it is easiest to explain everything in a video, so it is easier to understand for you guys and hopefully also helpful. It took me a long time to put everything together. Why? Because it was important for me to reuse as many original parts as possible to preserve the history of this camera. I think this is a very important part when you consider to renovate a piece of history! Underneath the video are all links for the parts I needed.

    Inspired Series – Jonathan Hetzendorfer

    I eat mushrooms as a meat substitute more often these days and once I started to buy specialities like oyster mushrooms from Jonathan, it was like a game changer. I knew his shop long before his first TV appearance, but never met him in person before. When I talked with him for the first time it was inspiring to see how much passion Jonathan puts in his work. I also remember when I ordered a mushroom dish in a restaurant and saw the menu that said “Fresh oyster mushroom from Jonathan”.
    You can tell he does something right, when gourmet chefs buy exclusively from him. Enjoy the video and if you are interested in a beautiful fine art print of that mushroom, just contact me here: https://www.markus-hofstaetter.at/pages/kontakt/

    Growing Together – World Wet Plate Day 2022

    I decided to participate this year for the world wet plate day. I discussed it with my girlfriend and she was the one who came up with the idea. First we thought to make it in one shot, but I couldn’t wrap the outcome into my mind because of the limited depth of field. So I came up with the double exposure solution. I was pretty happy with the outcome, but thought I could improve it a bit -> that was not my best idea (happy I did a scan before that). As you can see in the video, I got also unlucky with the varnish. So I am working right now on that to fix it. I will write about my result here on ma Patron page, you can support me and join here: Become a Patron!

    Changing my camera gear – iPhone 13 Pro Max – DJI OM 5 vs Hohem iSteady V2

    Filming with my Canon 5D mkIV and my M50 is sometimes pretty complicated. When I shoot wet plates, I do most of my videos by myself. Doing wet plate alone is a intensive task sometimes, combining it with capturing myself during the process can be challenging. Thats why I was looking for an easier solution. I wanted to have camera that shoots 120 or 240 fps in combination with a good autofocus for normal footage. First I thought of the wonderful Canon EOS R5. But to be honest, this wouldn’t make my life much easier. So I went for an iPhone 13 pro max in combination with the DJI OM 4 gimbal. the iPhone kills my Canon EOS M50 in low light video mode (when I use it in my darkroom with red light). It is amazing how far tech has come that days. What else I use and why the Hohem iSteady V2 is not for me, but could be the better solution for you can you find in this video.

    Wet Plate Talk and on location shooting at Fomo Graz

    Fomo Graz stands for Fotomonat Graz and translates to month of photography in Graz. The Fomo team invited me to do a talk and also shoot collodion wet plate portraits on location there. Thanks a lot for the invite it was such a great event and also thanks a lot to https://www.atelierjungwirth.com for letting me use your location to work on my portraits there. We had a blast, so many interested people during my talk. I really enjoyed explaining my favourite process to you guys. Also the wet plate portrait shoot was great, so many people wanted their portrait done. I think I shot 22 portraits on that day. Check out the video underneath for more impressions from this event. You an enjoy the video on a 4K screen with HDR support!

    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!
    If you liked this kind of projects and want to support my upcoming ones, you ca do that here
