## Description

Fotio turns your iPhone into a precise light meter for fully mechanical and manual film cameras.
Point it at your scene, read the exposure, and dial in ISO, shutter, and aperture against a live viewfinder. Lock any settings you want to keep fixed and Fotio auto-compensates the rest to keep your exposure on target.

FEATURES
• Viewfinder-first metering — the whole screen is your scene
• Center-weighted metering by default, with tap-to-spot and long-press to reset
• Full exposure-triangle control: ISO, shutter speed, aperture
• Lock any dial and the others auto-compensate to hold correct exposure
• Real APEX exposure math with a live EV-offset readout
• Camera presets — each camera carries its own array of stops
• Capture log — save your chosen settings with a framed reference, kept in a private in-app gallery (your photo library stays untouched)
• Color / B&W preview

Everything stays on your device — captures live in Fotio's own gallery, nothing is uploaded and nothing lands in your Photos.
