Building a Wet Plate Frankenstein Camera and Capture a Ghost

Corrine of booked a wet plate workshop before the pandemic started. Two years later we were finally able to do it. The main subject was to get comfortable with the wet collodion process and to create images similar to the ones of spirit photographer William H. Mumler. Mr. Mumler created images (probably double exposures) where his clients could take a picture with their deceased relatives. The photograph of Mary Todd Lincoln with the “ghost” of her husband (Abraham Lincoln) was his most famous one. Corrine found my double exposure wet plates and that was the reason she contacted me in the first place. About two months before the workshop Corrine surprised me with a question: “Can we build a wet plate camera together?”. I talked with a friend and after a long visit at a DIY market I was sure that we can do it. A DIY Camera and capturing ghosts, that sounds like a fun workshop for me 🙂

I could not capture everything in the video, because I was focused to deliver a great workshop experience. So let me explain a bit here. I build a diy camera kit so to say. But I did not want to build everything. It was important for me that we put the major parts together in person, to really create a camera and an understanding how a camera works.

the camera kit

It took me a long time to figure everything out, I wanted to create a diy camera, that is adaptable and upgradeable without any special parts. It also should be able to shoot portraits and landscape and if something breaks, just go to your diy marked and get a replacement part. The only thing needed is my self designed camera back. I wanted to invent/adapt something that you can get in the market, but I was without luck finding such a part. The 3D printed design took many hours and a lot of filament to work as expected.

The first prototype of the camera back with an international film holder

For the lens I went for a 150mm Leitz Dimaron (F2.8), Elmaron (F2.8) or Hektor (F2.5). These lenses have three things in common. 150mm is kind of a “normal” lens for the 4×5 large format and they all have the same diameter and not too expensive if you buy them online. All of them are pretty sharp as well as you could see in the video (this was a Dimaron)

one lens mount, lots of options without breaking the bank

The camera and lens support is build like this one in that posting: Camera and Lens support

For the Film/Plate holder I decided to go for the std international 4×5 holders. I had them water jet cut for a clean look and we modified it with silver wires, because these are more resistant against acid and fit into the silver nitrate workflow

We were super happy with our first result. The portrait looked awesome and the resolution of the lens is great. When you look closely at the video you will see, that we used two boxes for portrait distance.

the ground worked also great – here is a explanation how we did it
For me it’s always exciting to see my idea come to life.

Here is a detail scan of Corrine’s eye – pretty impressive result of a 4×5 plate shot with a self made camera and a projection lens.

For the spirit photographs that are inspired by Mr. Mumler we wend for wet plate double exposures.
To make our live easier, we marked all positions with sticky tape on the ground.

tape is always your friend for any photography project

We decided to use my Dallmeyer 3B Petzval lens for the first double exposure, because it fits better to the time when the original images were captured.

The second double exposure was a bit more modern, but also should get the ghost look. For that we used a Zeiss 300mm F4.5 Tessar lens. This lens is pretty new (about 2ß-30 years old) and is very crisp. I thought that makes more sense for this kind of image and also fits to the story (see caption of the image)

Profession – Yesterday, Today and Tomorrow An image about photography has changed

What a great 3 Day workshop that was. We created so many different portraits. (more in the gallery) and time flew so fast. At this point I want to say thanks again to Corrine for visiting my workshop and trusting me with the camera design. I looking forward to see what she will do for her PHD with the wet collodion process.

    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: 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 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 helped me out to model for me. Thanks a lot!
