Right Bright vs DevClock

Designed for analog photographers who can't easily check the effect a manual flash will have on their exposures, Right Bright helps by showing an intuitive aperture/distance chart based on the power of the flash and the ISO of the film being exposed. KEY FEATURES: • Simple, intuitive interface • Real-time distance calculations • Visual range indicator for each aperture • Adjustable flash power settings (1/1 to 1/128) • Works offline - no internet required • No ads or tracking HOW IT WORKS: Enter your flash unit's Guide Number, and the ISO setting you're working with, and Right Bright instantly shows you the effective working distances for common aperture values.
