Darkplug vs DBW PinholeCalc

Darkplug is a darkroom timer and printing tool for iPhone. It lets you control your enlarger from your iPhone using a compatible Shelly smart plug on your local network. Built for film photographers and darkroom printers, Darkplug combines precise timing, guided workflows, and a red-on-black interface designed for darkroom use. The clean timer interface is designed to stay practical under safelight conditions, with large controls and minimal clutter. Darkplug+ unlocks advanced printing tools, including F-Stop timing, guided test strips, dodge and burn planning, split grade printing, guided paper developing, and reusable Dodge & Burn plan codes. The guided test strip workflow helps you build and run exposure tests in seconds or F-Stops, then apply your preferred result as the print time. The Dodge & Burn workflow helps you plan local exposure changes, review a generated print plan, and follow guided execution steps in the darkroom. Plans can be exported and restored later with reusable plan codes. Darkplug also includes a guided developing timer for developer, stop, fix, and wash, so printing and paper processing can stay in one focused app. To use Darkplug, connect your enlarger to a compatible smart plug, make sure the plug and your iPhone are on the same local network, enter the plug’s local IP address, and connect. No account login is required. No cloud backend or external web service is needed for core timer operation. Compatible smart plugs: Shelly Plus Plug S Gen2, Shelly Plus Plug UK Gen2, Shelly Plug S Gen3, Shelly Outdoor Plug S Gen3, Shelly Plug M Gen3, and Shelly Plug US Gen4.

DBW PinholeCalc is a simple exposure companion for pinhole photographers working with black and white film or photographic paper. Save your camera, enter the aperture and time your light meter gave, and get one big final exposure, then time it from your iPhone. • Cameras: save your pinhole camera by its f-number, or for a homemade camera enter the hole size and the pinhole-to-film distance and the app works out the f-number for you • Exposure: converts your meter reading to your pinhole's aperture, then applies reciprocity correction to the converted time, in the right order, with a big result and a START TIMER button • Film and paper: manufacturer-published reciprocity data for popular films, or add your own film or paper with your own reciprocity exponent, clearly labelled as your own figures • Timer: large full-screen timer that keeps accurate time and stays awake while running, with a soft chime and haptic at the end • Light, dark and red night modes, big touch targets, VoiceOver and Dynamic Type Supported films, each with its data source shown in the app: • Ilford HP5 Plus, FP4 Plus, Delta 100 Professional, Delta 400 Professional, Pan F Plus • Kodak Tri-X 400, T-Max 100, T-Max 400 • Kentmere Pan 100, Pan 400 • Fomapan 100 Classic, 200 Creative, 400 Action Photographic paper used as a negative is not in the built-in list because there is no published data for it, so add it as your own material and start with an exponent of 1.0. An external light meter is needed. The app does not use your camera. The chime and haptic play while the app is open, so keep it on screen during an exposure. No account, no ads, no tracking, no internet needed. The app collects no personal data. Made by Digital Black & White. Pinhole exposure is partly a matter of testing, and results depend on your film, developer and conditions, so treat the result as a starting point and bracket.
