Cinema Lens View

CineCam Tool is a set-ready production tool built for professional camera operators and cinematographers — designed to be used directly on set.

■ FOV SIMULATOR
Uses your phone's physical lens to overlay the field of view of a cinema camera and lens combination directly on a live preview. Supports mount adapter calculations. Switch between two saved setups (FRAME A / FRAME B) to compare, with your last configuration remembered automatically. Camera bodies and lenses can be selected by manufacturer.

■ COLOR METER
Turns your phone into a color temperature and hue meter, showing live color temperature (K), hue, and RGB values from a spot in the center of the frame. Freeze the reading, tap anywhere else on screen to compare, and see the difference (ΔK, ΔHue, ΔRGB) at a glance. Choose between RAW mode (on supported devices) and Manual mode, and calibrate against a known light source using two points for improved accuracy.

■ FRAME RATE CALCULATOR
Calculates slow-motion and fast-motion multipliers and resulting duration from your shooting and playback frame rates, with a simple motion preview to visualize the effect.

■ STORAGE CALCULATOR
Estimates remaining recording time based on a measured data rate, with support for calculating from file count as well.
