Reciprocity Timer vs PhotoWatch

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!

The best photo opportunities always seem to happen when you're not looking. Getting great light isn't an accident. It's just a case of doing the research. Chasing light at a coastal headland, a dark-sky ridge, a tidal rock platform you've been circling for months. It all takes time and effort. PhotoWatch watches those spots for you, around the clock. When the weather, the tides, and the night sky align, it finds you. HOW IT WORKS Tell PhotoWatch where you're going and what you're looking for. An amazing coastal sunrise. A clear Milky Way window. A low-tide rock platform at sunset. You can even tell it how far in advance you want to be notified. Choose the conditions you need and PhotoWatch sends you an alert when they are all met. With Pro you can fine-tune each one, for example "I want high cloud more than 40% and just a light breeze". Then relax and let PhotoWatch go to work for you. When conditions line up, PhotoWatch sends you a push notification showing every location where conditions have come together. All you need to do is choose where to go. It will be quiet by default. You only hear from PhotoWatch when it's worth heading out. WHAT PHOTOWATCH MONITORS • Cloud cover at low, mid, and high atmospheric levels, the way photographers actually think about clouds rather than just "partly cloudy" • Rain • Wind speeds and direction • Sunrise, sunset and moon timing • Galactic core visibility, including when the Milky Way clears the horizon and the sky is dark enough to shoot (Pro) • Tides and Swell including height, state and timing at your coastal spots (Pro) • The possibility of fog (Pro) To top it all, the app works anywhere in the world.
