Right Bright vs Silverlog Flash

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.

Silverlog Flash calculates flash exposure using guide numbers — the fundamental relationship between flash power, distance and aperture. HOW IT WORKS Enter your flash guide number, then either the distance to your subject or your desired aperture. The calculator works both ways: distance to aperture, or aperture to maximum distance. Adjust ISO to see how sensitivity affects your working range. FEATURES • Guide number to aperture calculation • Guide number to maximum distance calculation • ISO adjustment • Metric and imperial distance units • Works offline — no internet connection needed • Clean, focused interface • Dark mode support USEFUL FOR • Manual flash photography without TTL • Working out flash-to-subject distance for off-camera flash • Understanding your flash's effective range at different apertures • Film photographers using manual flash units • Studio photographers calculating lighting ratios Part of the Silverlog photography toolkit.
