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 the realm of large format photography, intimidated by the vintage cameras and expensive film required. That all changed with 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, created by Toby Wilkins, a semi-retired British filmmaker, has revolutionized my approach to photography, making large format photography more accessible and less intimidating.
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. By replacing the camera's ground glass focus screen with a new, proprietary screen, the ObscuraFlex enables digital capture with an iPhone, Samsung Galaxy S25 Ultra, or Ricoh GR III or IV series camera. This eliminates the need for film, making the process of using a large format camera much less daunting for beginners.
One of the most fascinating aspects of the ObscuraFlex is its 'secret sauce' focus screen, which Wilkins describes as a 'smoother, crisper, and more even exposure' than traditional ground glass. This screen diffuses light more effectively, providing a 'crisper and more even exposure' that is crucial for achieving the desired look and feel of 4-by-5-inch film. The high-end 3D printing techniques used in the ObscuraFlex's design, along with its sturdy construction and light-tight bayonet mounts, make it a well-crafted and reliable tool for photographers.
Despite some initial challenges, such as light leaks with the iPhone 17 Pro, Wilkins is quick to address issues and has already improved the product. The modular cradle system allows for easy switching between different cameras, and the ObscuraFlex app provides a user-friendly interface for setting up shots, making manual focus more accessible. However, the app is limited in its ability to adjust focus points, and low light conditions can pose challenges for achieving sharp focus.
Large format photography presents a higher degree of difficulty than 35mm or medium format, and I need more practice to make the Crown Graphic sing. But the convenience of digital capture and the ability to experiment without the cost of film and processing make it a rewarding experience. The 4-by-5-inch image area and the 'secret sauce' focus screen add a unique texture and character to the images, creating a desirable analog look in an age of digital perfection.
In conclusion, the ObscuraFlex is a game-changer for photographers who want to explore large format photography without the hassle of film and processing. It offers a more accessible and cost-effective way to achieve the look and feel of traditional large format cameras, making it a valuable tool for both beginners and experienced photographers alike.
