Aquarium Camera is built specifically for aquarium owners who are tired of their tank looking incredible in person and disappointing on their phone. LED aquarium lights are brilliant, but blue actinic lighting interferes with camera sensors, shifting the colors of your fish, plants, and corals into something far less accurate. Standard camera apps were not made for this. Aquarium Camera was. Designed for reef tanks, planted tanks, freshwater aquariums, and fish-only setups, Aquarium Camera helps you capture photos and videos that better reflect what your tank actually looks like. “The Aquarium Camera app is an essential tool for reef tank photography.” – ReefBuilders.com You can stop buying pro camera rigs, shooting in RAW, using clip-on filters or gels, and turning off your blue lights just to get a decent shot. You do not need to spend hours in editing apps adjusting hue, tint, and exposure after the fact. Aquarium Camera helps you color-correct aquarium lighting in real time on your iPhone or iPad, using the device you already carry every day. Version 4.0.0 is a complete re-architecture built to maximize the performance of your iPhone and iPad. Features: • Real-time lens filter mode that dynamically helps balance your shot • 32 custom professional-grade lens filters in manual mode • Real-time tint, temperature, RGB, and exposure adjustment • Full-resolution photo capture • 4K video recording • Syncs with iCloud • Support for your device’s available camera lenses, including wide, standard, and telephoto • Save and share presets once you dial in your tank • Side-by-side preview to help fine-tune color balance • Portrait and landscape support • Touch to focus • Flash toggle • Grid toggle • Quick access to your aquarium gallery with export or autosave to library • Share photos and videos right from the library • Volume button shutter support • Haptic feedback • No subscription: buy it once and unlock everything on iPhone and iPad “So easy to use… Love it!!! And the color changing is realtime so you can see the screen and the real thing side by side to ensure you get the right balance.” – Carlos Chacon, CoralVue I created Aquarium Camera because I was tired of seeing brilliant aquariums online that did not truly represent the health, color, and beauty of the fish, plants, and corals inside. As LED lighting took over the hobby, aquarium photography became harder. Aquarium Camera is my answer to that problem. Spend less time correcting aquarium photos and videos, and more time enjoying your tank... oh and doing water changes.
