Home Screen widgets, a long exposure countdown with Live Activity, and fully redesigned zone metering. Light meter now reaches 16-minute shutters. Calculators refreshed.
GroundGlass is a shooting log app built for large format photographers.
Whether you shoot 4x5, 8x10 or any other format, GroundGlass captures every detail of the moment you press the shutter — from exposure settings and Zone System metering to camera movements and development records.
KEY FEATURES
