Description
Calculate and compare aperture, shutter speed, shutter angle, frame rate, light sensitivity, and transmittance values. Configure the interface to suit your workflow.
Over | Under is a simple and intuitive tool that gives photographers and cinematographers the ability to calculate and compare common photographic exposure parameter values – aperture, shutter speed, shutter angle, frame rate, light sensitivity, and transmittance.
Over | Under was created by working cinematographers for professional image makers, students, and hobbyists alike to help answer the questions that frequently arise on any set:
How much light will I lose if I close the lens aperture down from f/1.8 to f/5.6?
I can't add more light, but I want to maintain the same exposure level I had before I changed the aperture. My shutter was set to 1/2000s of a second; what should it be to compensate for the light loss?
I was shooting video at 24fps with 5 stops of ND in the matte box. I switched to 120fps for a slow motion sequence, and opened the shutter angle to 227º to regain some motion blur. I will be switching to standard speed shortly, and don't want to relight twice. How many stops of ND should I remove to maintain the same exposure level?
Over | Under can answer these and many more questions, in a simple, intuitive interface inspired by an all-familiar aperture ring.
Ratings and Reviews
Must-have cine app
Love using Over Under as a DP, and I’m sure camera assistants will find it useful as well.
It’s great for designing bracketed exposure tests - since finding this app, I haven’t designed a camera test without it! I also find it helpful for calculating fractional exposure changes when I have to use specific shutter angles to compensate for flickering practicals. I especially love that I can calculate cumulative changes across multiple exposure parameters. And unlike many cine apps, this one is intuitively and cleanly designed. 🙏🏽
Brilliant, so very helpful!!
As a professional cinematographer I love this app, it’s so convenient to have this quick calculating power at your fingertips. Given all the things to think about and consider on set it’s nice to have a quick and easy way to reliably make exposure adjustments. It’s a great and handy tool to have!!
Useful for ACs
I’m a camera assistant who’s terrible at math so I find this super handy on set
