FinderKit

A fast, intuitive viewfinder app with the same intuitive interface as CameraKit and LensKit. Whether you’re scouting a location, testing a new angle on set, or making a quick photo-based storyboard, FinderKit will help you work faster and keep you and your crew in sync.

Simply choose your camera and lens package, and you’ll get an accurate preview of what your camera will see. Quickly scroll the lens list to change focal lengths—no need to manually tap through each lens to get to the one you want. Save photos and videos to the in-app gallery, where you can organize by project and scene, add notes, or share as individual files or as a PDF shotlist.

PROJECTS

Projects let you organize your work. New photos and videos are saved to the project currently selected, along with your most recent camera and lens selections. When you return to that project later, your media and camera/lens settings are automatically loaded.

GALLERY

With an easy to use design, the gallery makes it simple to view, organize, and share media. When viewing media, just swipe up to see metadata and add titles/notes. Swipe back down to return to the gallery. Media is automatically grouped by project, and you can further organize by scene if you choose.

PDF EXPORT

Besides standard exporting, FinderKit can create PDF shotlists with customizable options including image size, metadata details, and page orientation.

AND MORE

Fullscreen mode lets you cut out the distractions, hiding all the controls except the lens picker and shutter buttons. Looks let you dial in exposure, contrast, temperature, saturation and more. Multicam buttons store preset camera and lens combinations for easy access when you’re working with multiple cameras. What3Words option saves each photo with a 3-word address that’s more precise than a typical street address. A coverage warning lets you know that the lens you selected may not cover the current camera sensor (with a shortcut to LensKit to see the full coverage chart).

CameraKit

“How much drive space will I need for this Alexa 35 shoot?”
“Does the C300 Mk III have anamorphic modes?”
“What’s the dynamic range of the Venice 2?”
“How big is this H.264 file going to be when I export?”

If you’ve ever asked these questions, this is the app for you. Whether you’re making decisions on set, troubleshooting in an edit bay, or figuring out which camera to buy, we’ve got you covered.

NETFLIX APPROVAL

A game changer for anyone who’s struggled with the complexity of which cameras, formats and resolutions are Netflix approved— especially in anamorphic. Designed in collaboration with Netflix.

DEPTH OF FIELD

An easy to use yet comprehensive DOF tool that allows for customizing circle of confusion with presets and manual input.
