Reciprocity Timer vs Darkroom Assistant

Manage your film photography from start to finish!  Reciprocity Timer has 2 Version - the "Standard" Version does NOT include advanced features but can be used to calculate reciprocity on a range of common films. The "Pro" Version is available for an additional $9.99 USD (via in-app-purchase) unlocks a range of advanced features. The initial purchase price allows you to calculate reciprocity for all the films included by selecting an observed exposure time. This $1.99 US non-pro version is suitable for people who just need to calculate an exposure that includes reciprocity adjustments for commonly used films. It will suit many users who don't require or need to upgrade to the pro version for features like note keeping or a camera database etc. It's most suitable if you are new to film. More advanced film users and photographers may want to pay to upgrade after their initial purchase to the pro version. If you use a pro-feature you'll be prompted to upgrade for an additional $9.99 US. This will unlock all the additional features including the Zone Editor, Note, Camera and Film Holder database as well as custom films and filters. There is no need to upgrade if you just want to calculate and time reciprocity for a particular film and you always use the same camera. The app includes in-app purchase to unlock pro features including a note-keeping feature, the ability to add custom films and the ability to select often used film stock as favorites. Once you upgrade then the one app does it all - notes, filters, exposure calculations, custom films, zone system editor, film holder management as well as the reciprocity math! A comprehensive film reciprocity calculator for photographers. Select a film type and metered exposure time - the calculator will provide a reciprocity compensated exposure time. The app includes an exposure timer so you can time your long exposures. You can also use a slider to adjust exposure when you have filters attached. The app supports a wide range of film stocks and allows the user to add various common exposure filters such as NDs and Polarizers. Keep detailed notes and share them. Share your adjusted exposure times with colleagues. This app makes film photography a breeze. You may need to setup Reciprocity Timer in Settings -> Notification Center to ensure the app's timer can notify you when exposures are ending and your device is asleep. Watch companion app now included. To install the app use the Apple Watch App on your phone. Ensure your watch and phone are paired an unlocked and scroll down the list of available apps to Reciprocity Timer. Select Install. You can also turn on "Automatically Install Apps".

Make better darkroom prints—and preserve every decision that got you there. Darkroom Assistant is a purpose-built workflow app for black-and-white darkroom printers. It connects what you see in the print to the exposure, dodging, burning, and sequencing needed to make the next one. Map adjustments on the image, work in stops, and let Darkroom Assistant calculate the actual exposure times. You don’t need an expensive programmable f-stop timer to use an advanced f-stop printing workflow. Whether your timer counts in stops or only in seconds, the calculations, visual map, and printing sequence stay connected to the image. If you have ever made a great print and struggled to recreate it, searched through scattered notes, or wasted paper rebuilding a previous result, Darkroom Assistant brings the complete printing process together. It does not automate printing or replace your judgment. Your eye decides what the print needs. Darkroom Assistant translates that decision into the next exposure—and preserves the path when the session ends. VISUAL DODGING AND BURNING Map local adjustments on the print image instead of trying to connect handwritten times to remembered areas. Set the desired change in stops, and Darkroom Assistant calculates the corresponding dodge or burn times and organizes them into a clear printing sequence. A programmable f-stop timer can count exposure in stops. Darkroom Assistant goes further by connecting each adjustment to the image, calculating the time for that operation, and preserving the reasoning behind the print. PRINT PROJECTS AND PRINT LOGS Organize each image as a project and preserve the path from test strip to final print. Keep multiple interpretations together, compare them over time, and return later without reconstructing the session from memory. Record paper, developer, filtration, exposure, contrast, notes, and the decisions made along the way. A short version note on the physical print can lead you back to the complete plan in Darkroom Assistant. TEST STRIPS AND SPLIT-GRADE PRINTING Build and document test-strip and split-grade workflows inside the app. Compare results, refine exposure and contrast, and carry your decisions forward without starting over. SCALE PRINTS WITHOUT STARTING OVER When you change print dimensions, Darkroom Assistant can scale the exposure steps in the complete Print Log—not just the base exposure. Carry a successful plan into the new size and begin with a calculated starting point instead of rebuilding every exposure, dodge, and burn from scratch. Additional calculators help with changes in exposure, aperture, filtration, neutral density, and print size. DARKROOM TIMERS Use focused, distraction-free timers designed for printing and film-development sessions. FILM DEVELOPMENT Create and run film-development workflows with organized formulas, timing, and session records alongside your printing tools. BACKUP AND RESTORE Protect your darkroom library with manual backup and restore. LEARN AND GET SUPPORT Use the video guide and subscriber community for help. DARKROOM ASSISTANT HELPS YOU: • Translate visual decisions into precise exposure steps • Use an advanced f-stop workflow without an expensive programmable timer • Plan dodging and burning without calculating every time in your head • Scale complete printing plans when changing print size • Reduce avoidable paper and chemistry waste • Preserve successful prints and multiple interpretations • Spend less time reconstructing old sessions • Build a consistent, repeatable darkroom process BUILT BY A DARKROOM PRINTER Darkroom Assistant was created by a working darkroom printer with decades of hands-on experience. Its tools come from real workflows developed at the enlarger—not from an attempt to replace analog craft with automation. Practical tools for photographers who care deeply about the craft.
