Read full description

EMST Camera is a film-inspired camera app you operate like a camera. Not a filter you drop on afterwards. Pick a look, set your exposure, aperture and focal length, and shoot. Live preview of the settings directly in viewfinder. YOUR CONTROL β€’ A dial-based shooting interface: one scroll wheel drives exposure, aperture, focal length and aspect ratio. β€’ Aperture dial with depth-of-field rendering. β€’ Focal length presets pinned to your iPhone's real lenses. β€’ Mirrorless-style autofocus: a persistent AF box, tap to move it, AF lock to recompose. β€’ Grid and level overlays when you want them, nothing when you don't. YOUR LOOK β€’ Built-in film-inspired looks, from warm evening color to cool dusk tones and true monochrome + Natural for a clean, untouched capture. β€’ Every look is tunable: grain, halation, vignette, clarity and color temperature. PRIVATE BY DESIGN β€’ No account, no ads, everything happens on your device. Open the camera straight from control center or lock screen with shortcut extension.
