Description
Get the right flash power setting every time.
Flash Power measures the distance from flash to subject, then calculates the precise power setting for a well-exposed shot.
THE PROBLEM You are setting up a camera trap in daylight, so you cannot preview flash exposure against the ambient light. You need a way to calculate the correct flash power for a nighttime shot without returning after dark to take test exposures.
THE SOLUTION Flash Power gives you a fast, practical way to calculate flash exposure. Use the app to automatically measure the distance from flash to subject, or enter it manually, then set your aperture and ISO. The app calculates the flash power you need, so you can set up with confidence and avoid trial and error after dark.
WORKS WITH ANY MANUAL FLASH Preconfigured for Camtraptions F1, Z1/Z2, and Z Pro, but compatible with any manual flash. You can also create a custom flash profile by entering your flash’s guide number and zoom behaviour.
WORKS ON ALL PHONES • ARCore depth mapping, plus manual distance entry • No depth mapping? No problem — measure separately and enter the distance manually
BUILT FOR CAMERA TRAPPERS Designed for wildlife photographers using off-camera flash. No more test shots, no more guesswork, and no more blown highlights or underexposed subjects.
HOW IT WORKS 1. Hold your phone next to your flash and point it at your subject 2. The app measures the distance, or you enter it manually 3. Set your camera’s aperture and ISO 4. Read the recommended flash power
The app tells you exactly what power to dial in, from full power down to 1/128, with ⅓-stop precision.
FEATURES • Distance measurement with ARCore depth mapping, or manual entry • Preconfigured flash profiles for Camtraptions F1, Z1/Z2, and Z Pro • Custom guide number support for any manual flash • Zoom head compensation from 24mm to 200mm • Coverage preview to visualise flash spread • Real-time calculation as you adjust settings
THE SCIENCE Flash Power uses the guide number formula and inverse square law to calculate exposure. It takes aperture, ISO, flash zoom position, and distance into account, then gives you a precise power recommendation to get you close on the first shot.
Ideal for camera trap setups, macro photography, studio work, and any situation where you need consistent, repeatable flash exposure.
