Aperture
The opening in a lens through which light passes to enter the camera, affecting depth of field and exposure.
What is Aperture?
Aperture refers to the opening in a camera lens through which light passes to reach the image sensor or film. It's measured in f-stops (like f/2.8, f/8, f/16), with smaller numbers indicating larger openings. Aperture serves two crucial functions: controlling the amount of light entering the camera and determining depth of field. A wide aperture (small f-number) allows more light and creates a shallow depth of field, ideal for portraits with blurred backgrounds. A narrow aperture (large f-number) allows less light but produces greater depth of field, keeping more of the scene in focus, which is desirable in landscape photography.
AI Prompting Tips
For AI-generated images with specific aperture effects, use terms like 'shot at f/1.4' for shallow depth of field or 'shot at f/16' for deep focus. Specify 'wide aperture with bokeh' for portrait-style images with blurred backgrounds, or 'narrow aperture with everything in focus' for landscape-style shots. Including the phrase 'shallow depth of field' or 'deep depth of field' alongside aperture values helps reinforce the desired effect.
