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.
