I found a WWII British Air Ministry Pentac 8 inch f2.9 lens in a second hand store about a year and a half ago. It was made under a military contract during the war and a number of British manufacturers filled this contract. The best of the lot were made by Dallmeyer, the original designer of this lens. This lens sample isn’t marked to indicate the manufacturer, and it doesn’t have a traceable serial number, so the maker remains a mystery. Like many lenses that were made for aerial reconnaissance work, they were intended to be mounted on a camera with a built in shutter. To make this lens usable in a modern sense would involve controlling the timing of an exposure. Mounting this lens in a large format leaf shutter can be an expensive undertaking, and due to it’s size, the shutter options are somewhat limited. Because I’m of dutch descent (thrifty, cheap, frugal…), I took it upon myself to find an inexpensive solution to this particular problem… Bonjour Marie Antoinette.

The idea of this camera started with vintage Profile Spotlight, that I wanted to restore, but found out, that some of internal lens elements were shattered. The only lens element, that was undamaged was the front element of it. Upon some closer inspection I discovered, that this element can project image circle big enough, to cover 8X10 area.
The obvious use of it was to create large format camera. but I didn’t want to bother with large format film and other hassles of creating proper large format camera, just for this weekend experiment. So, I decided to create something like Camera Obscura and photograph projected image with DSLR.
Large format film still holds a huge draw for a lot of photographers. It has a look that the relatively tiny digital sensors today (yes, even the medium format ones) just aren’t capable of. But shoot large format on film can be a laborious task. For many, the end result is worth it, but if you want slightly more immediate results, digital scanning backs are the solution.
The problem is, digital scanning backs for 4×5 cameras can be very expensive (and they’re not exactly common). In this video, Sean at Fotodiox shows us how we can turn a simple small portable flatbed scanner into a digital scanning back for a large format camera.
These days, if you want to shoot large format, you might have difficulty finding replacement parts. Large format cameras aren’t exactly as common as they used to be, and there aren’t many companies making spare parts for older ones these days, or creating custom pieces for odd-sized cameras.
In this video, though, photographer Markus Hofstätter walks us through how we can make our own ground glass focusing screens at whatever size we need.
The Chroma 4×5 large format technical camera has intrigued me since it was announced last February. When I found out its creator, Steve Lloyd, was UK based, I got in touch to find out if he’d planned to visit The Photography Show this year. It turned out that he had, so I asked if he could bring along one of his Chroma cameras so I could see it for myself.
Animation filmmaker and self-taught photographer Ursula Ferrara has made her own 16″ x 20″ camera entirely from scratch. She shares some images of the creating process, as well as the resulting photos. Her daughter, Annick Emdin, describes the magical process of being photographed by this camera, made with a lot of passion and devotion.
We’ve seen a few remarkable experiments with large format cameras. But young photographer Zev Hoover added something new to it: motion. He made a working 8×10 large format digital video camera, most likely the first of its kind. He shares a video he shot on this unusual camera but also talks a bit about how he made it.
One of the things that the COVID-19 pandemic has taught us it that many more people can work from home than most of us previously thought. It’s brought online video conferencing to the forefront of our minds, but with everybody buying up webcams, the decent ones are pretty much impossible to find now. Chances are, demand for webcams will say high for a while, too.
Well, Fuji has now launched its new Fujifilm X Webcam software for Windows. With the assistance of a USB cable, it allows you to turn a number of Fuji cameras into webcams for use with your computer to get results better than anything you could hope for with your standard USB webcam. It even works with their medium format GFX cameras.
The title of this post is a somewhat rhetorical question, because whether or not you’ll be able to tell the difference largely depends on what you’re shooting, the lens you’re using, the level of tech in the sensor and how the final image is going to be displayed. But there are definitely some differences between sensors at different sizes.
In this video, The Slanted lens takes a look at four cameras with different sensor sizes in various conditions to see how they stack up against each other. Interestingly, they don’t just pixel peep on the computer screen, either. They also make 24″ prints to see if you can really spot the difference in the real world.
So, I’ve posted my 8×10 camera on several photography groups and I’ve gotten a lot of interest. I figured I’d do a little write up for anyone that wanted to know more about the camera as well as see some images of the building process.
