The Blackmagic Camera App for iPhones (download here) has proven to be pretty popular. This isn’t much of a surprise, considering they’re giving it away for free. It essentially reproduces the look and feel of a Blackmagic camera on your iPhone.
Blackmagic has released the new v1.1 version of the app, which provides some very useful updates. There’s support for the Tilta Nucleus Nano (buy here) and Nucleus M (buy here), as well as Tentacle Sync E (buy here) support for external timecode.
