Right Bright vs FlashFlashApp

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.

Know your flash settings before you shoot — not after three test frames. FlashFlash is a manual flash calculator built on the Guide Number method. It solves in both directions: POWER CALCULATOR Set your aperture. FlashFlash tells you exactly what power fraction to dial in — 1/4, 1/16, whatever the shot needs. APERTURE RECOMMENDER Set your power level. FlashFlash tells you exactly which f-stop to use. Battery-constrained, locked into a specific power level, planning a shot before you arrive — this is the tab for it. No test shots. No chimping. Enter your settings, read the answer, nail the exposure. WHAT YOU ENTER · Guide Number — type it manually or pick from 100+ built-in presets (Godox, Canon, Nikon, Sony, Profoto, Elinchrom, and more) · ISO · Aperture or power level — depending which tab you're on · Flash-to-subject distance · Flash zoom from 24 mm to 200 mm · Filter compensation for gels, diffusers, and softboxes WHAT YOU GET · The exact power fraction or f-stop, snapped to a real standard setting · Effective GN and Required GN — so you know exactly how much headroom you have · A live scene visualization: your flash, your subject, your light cone, updating in real time · A power bar showing at a glance how hard your flash is working ON CAMERA OR OFF FlashFlash always asks for flash-to-subject distance — not camera-to-subject. Because when your flash is on a stand three feet from your subject and you are eight feet away, those numbers are not the same. And that difference is everything. FULLY OFFLINE No account.
