The Cinematography Electronics FLICKERfree Calculator is a handy tool to calculate the proper camera speed and shutter angle combinations for FLICKERfree film or digital cinematography. It is especially useful when using HMI or fluorescent lighting.
Our FLICKERfree Calculator is designed with the same simplicity as our popular HMI Flickerfree Filming Speeds reference cards. Our App calculates the camera speed in Frames Per Second (fps) and camera Shutter Angle in Degrees. The colors on the calculator, Burgundy (50 Hz) or Blue (60 Hz), also match the colors on our reference cards.
