HTBT
Read full descriptionHide full description
You had to be there. HTBT is a shared disposable camera for your people. Start a roll, set how many shots it holds and when it develops, then pass it around the room. Everyone shoots the same roll, and nobody sees a thing until it is done. HOW A ROLL WORKS 1. Start a roll. Pick a shot count and a reveal time, then invite your people with a code or a link. 2. Shoot blind. No preview, no retakes, no scrolling back. You point, you shoot, and you trust the moment. 3. Develop together. When the timer hits zero the whole roll develops at once, and the night lands in everyone's hands at the same time. WHY IT FEELS DIFFERENT No previews means no posing for the screen. No retakes means the real moment, not the fifth attempt. One shared roll means the night told from everyone's angle, not just yours. And because nothing develops until the timer ends, the anticipation is half the fun. Perfect for parties, trips, weddings, birthdays, concerts, late nights, and any moment that deserves film. Some nights deserve film. Start a roll for the next one. Privacy Policy: https://htbt.app/privacy Terms of Service: https://htbt.app/terms
Knurl Camera

Knurl is a camera for people who would rather develop the photo themselves. It captures true Bayer RAW: the sensor's own mosaic, written straight to a DNG with none of the computational photography that normally happens on the way. No multi-frame fusion, no tone curve, no sharpening. What lands in your library is undeveloped data with all of its latitude intact, ready for Lightroom or Photos to interpret however you like. THE CONTROLS ARE THE POINT A mode wheel you turn, with the real designations: P for program, Tv for shutter priority, Sv for ISO priority, M for full manual. Every position clicks. ISO and shutter move in thirds of a stop along the standard photographic ladders, on a dial that detents at every rung. Whole stops click harder than thirds, so you can count them by feel without looking. The ends of each ladder are the sensor's genuine limits rather than round numbers, which means base ISO, the cleanest the sensor gets, is actually reachable. Exposure compensation on its own scale, in thirds, with a firmer detent at zero. In manual it becomes the meter, because compensation has nothing left to act on when both controls are already fixed. An AF/MF switch and a focus ring you turn like a ring: relative, so touching it never jumps focus, and marked near to far rather than in invented distances. Three lenses, each at its native focal length, read from the hardware. HONEST ABOUT ITSELF Bayer RAW is 12 MP and does not permit zoom. The 48 MP path would mean Apple ProRAW, which is demosaiced and partially processed, so Knurl does not offer it. When the exposure you have asked for is not achievable, it says so rather than pretending. Your shots go to a Knurl album you can browse in the app, pinch to zoom, and swipe through. Volume buttons fire the shutter. Add the Control to your Action Button, Lock Screen or Control Center to open it without unlocking.
