As photographers and videographers, we're always taking crop factor into account. The problem is, we're always comparing our focal lengths and fields of view to what they would look like on a full-frame camera. What if you don't have a full-frame camera or what if you've never shot on a full-frame camera to have any idea what those lenses would look like? Well Fallowfield allows you to pick your point of comparison. Fallowfield is an app that allows you to calculate field of view between any 2 cameras. Let's say you're considering buying a new camera with a new lens. Maybe you want to pick up a Blackmagic Pocket Cinema Camera with a 20mm lens and you currently own a Canon Rebel. Well with Fallowfield, you'll be able to easily figure out what a 20mm lens on a BMPCC will look like on a Canon Rebel. Of course, you can always pick a full-frame camera as well if you're curious how that will look. Don’t see your camera in the list? No problem! Fallowfield lets you enter custom crop factors. If you don’t know your crop factor, you can also enter your sensor dimensions. With a growing list of cameras and internet-search-based crop factors, we hope that our community of users will submit any errors or omissions. Enjoy this simple little app that helps you get a real-world sense of crop-factors.

"A good photograph is knowing where to stand." — Ansel Adams Darkcloth is a field viewfinder for technical and view cameras. Use the phone camera to preview the frame before you set up the camera. Choose a film format and focal length, add rise, fall or shift, compare lenses, and check level. It is meant for planning the photograph, not replacing the ground glass. Included tools: • Framelines for 6×7, 4×5, 8×10 and custom formats • Multiple focal lengths at once for lens comparison • Rise/fall and shift preview over the live scene • Reflected-light meter with average and spot readings • Reciprocity correction for common film stocks, plus custom stocks • Roll and pitch level • Scheimpflug tilt visualiser with near/far depth-of-field readout Darkcloth was made alongside the Fysh FTC-1, but it is not locked to that camera. It works with other technical-camera and view-camera workflows. No account is required. No photos are uploaded.

Verdict
The clearest difference is update cadence: Darkcloth at every 10 days against Fallowfield's every 3 weeks. Fallowfield's advantage is device support (3 vs 1) and iOS requirement (10.2 vs 16.0). On price, ads and in-app purchases there is nothing between them.
