I've been a photographer for over two decades, and I've used all sorts of cameras, from rangefinders to mirrorless digitals. But I never dared to venture into large format photography, intimidated by the vintage cameras and expensive film sheets. That all changed when I discovered the ObscuraFlex, an innovative add-on for view cameras that lets you skip the film and use a smartphone or compact camera as a digital back. This device is the brainchild of Toby Wilkins, a semi-retired British filmmaker, and it has completely transformed my approach to large format photography.
The ObscuraFlex is a chimney-shaped accessory that attaches to the back of a Crown Graphic camera, a classic press camera that uses 4-by-5-inch sheets of film. It replaces the camera's original ground glass focus screen with a new one made from a proprietary material, diffusing light more effectively for a smoother, crisper, and more even exposure. This 'secret sauce' focus screen is the key to the ObscuraFlex's magic, allowing you to capture images with a large format camera without the need for film.
Using the ObscuraFlex is a more careful and convoluted process than I'm used to, but the results are worth it. The 4-by-5-inch image area is huge, and the tilt movements allow for creative compositions that 35mm cameras can't match. The vintage lenses add characterful bokeh, giving the images a distinct analog look. While there are some unavoidable imperfections, like dust spots on the focus screen, they add to the texture and character of the images.
One of the biggest challenges with the ObscuraFlex is low light. The focusing screen isn't super bright, and most large format lenses have dim maximum apertures. This makes it best used in sunlight or brightly lit interiors. However, the ObscuraFlex's multi-shot computational Raw imaging helps conquer dim light, assuming you can get the focus right.
The ObscuraFlex is a wonderful tool for photographers who want to learn to use a large format camera, as well as for experts who want the convenience of digital. It's available for cameras that use standard Graflok mounts and Mamiya mounts, and prices range from $350 to $400 for a full kit. While it's not a universal solution due to the lack of a standard for large format cameras, Wilkins is working on adding support for additional bodies.
In conclusion, the ObscuraFlex has completely changed my perspective on large format photography. It's a fascinating tool that allows you to capture stunning images without the hassle and expense of traditional film. I highly recommend it to anyone interested in exploring the world of large format photography.
