FEATURES

LIGHT METER
Accurately meter light with your smartphone camera. Set your film's ISO rating and get precise aperture and shutter speed combinations to achieve perfect exposures. Works for all lighting conditions, helping you nail your shots even with cameras that don't have built-in meters.

RECIPROCITY CALCULATOR
One of the most useful tools for long exposures. When shooting longer than 1 second, many films suffer from reciprocity failure requiring longer exposures than metered. Select your film stock, enter the metered exposure time, and let the app calculate the adjusted time needed for proper exposure.

BLACK AND WHITE PREVIEW
See the world in monochrome before pressing the shutter. This feature helps you visualize contrast and composition without color distraction, making it easier to determine if a scene will translate well to black and white film.

COMPASS
Get your bearings with a simple, accurate compass. Essential for landscape photography when planning compositions based on direction of light, tracking the sun's path, or recording shooting locations.

NOTES
Keep organized records of your shoots with free-text notes. Features useful one-press shortcuts to add timestamps and GPS coordinates. Document your shots, settings, locations, and observations to learn from each roll.

CUSTOMIZABLE SETTINGS
Configure the app to match your workflow. Adjust units, default values, and behaviors to make the app work exactly how you prefer.
