Darkroom Studios is a workbench for analog printing. It keeps track of the gear you own, the darkrooms you build from it, and every print you pull — so a result you liked six months ago is a setup you can repeat tonight. REGISTER YOUR GEAR Add your enlargers, lenses, easels, timers, and chemistry. Each item carries the details that actually matter at the baseboard, so you are not guessing which lens was on the column for a print you made last spring. BUILD REPEATABLE DARKROOMS Group gear into named darkrooms — a full working setup you can select in one tap. Set one as your default and every new session starts from known ground. RUN GUIDED SESSIONS A printing session walks through nine steps, from exposure to wash. Each stage is timed against the wall clock, and the app notifies you when a stage is over, so you can keep both hands on the print instead of watching a timer. DIAL IN THE PRINT Set contrast grade, exposure time, aperture, and darkness before you commit, and see a live preview rendered from your own photograph. Burn and dodge to shape the result. The preview works from the actual image you are printing — it is not a stock simulation. KEEP EVERY RESULT Photograph the negative or the finished print with the camera, or pick an image from your library. Each completed session is saved with a rendered print and the full parameter set that produced it. Save finished prints back to your photo library or share them. NO ADS, NO TRACKING There is no advertising in Darkroom Studios and no analytics or tracking SDK of any kind. Your gear, your sessions, and your images are yours.
