3D-printed flashcards for aperture, shutter speed, ISO, and the exposure triangle — made for photo students and hobbyists.
About
Camera Keys was created by a photography teacher in downtown Los Angeles who teaches inner-city youth. The keychains are made to teach manual exposure and creative photo techniques — a small reference you can keep with the camera, so you can check a setting and keep shooting.
The cards
Six 3D-printed keychain cards. Each one is a compact flashcard for a camera setting or a shooting situation. The images are 3D-render placeholders, not product photos.

Blue · Focus Depth of Field
How aperture shapes focus: a wide opening such as f/2.8 gives a shallow field with more blur; a smaller opening such as f/16 keeps more of the scene sharp.

Green · Light Low Light
Three ways to gather more light in dim conditions: a wide aperture, a slower shutter, or a higher ISO — and the trade-offs of blur and noise.

Green · Light Sunny 16
The sunny-16 rule: in bright sun, set the aperture to f/16 and the shutter to 1/ISO, then open up as the light falls, toward overcast.

Red · Exposure Brighter vs Darker
The exposure triangle on one card: matching scales of aperture, ISO, and shutter speed, from brighter settings to darker ones.

Orange · Action Action
Shutter speed and motion: slower speeds such as 1/2 second smear movement; faster speeds such as 1/500 freeze it sharp.
