Drawing with light
- Photography 摄影 makes images with light and a lens.
- The same elements and principles apply to the frame.
- It is a lens-based 2-D art, digital or darkroom.
The key controls
- Key controls: framing, focus 对焦, exposure 曝光 (light), depth of field 景深, and viewpoint.
- Light direction and quality shape value, form, and mood.
- The rule of thirds, leading lines, and negative space compose a photo.

Framing, focus, and light are creative controls; the printer brand is not.
Match each control to its effect.
Depth of field = focus; exposure = brightness; framing = inclusion.
Editing is part of it
- Editing 后期 (cropping, contrast, colour) is part of the creative process, not just correction.
- Composition can be refined after the shot, by cropping.
- Digital and darkroom processes both count as lens-based art.
Editing choices like cropping and contrast are part of the creative process in photography.
Editing is a creative decision, not just correction.
Photography is making, not just taking. Choices of framing, focus, depth of field, light, and editing are all creative decisions. A snapshot and an artwork can show the same subject — the difference is the deliberate use of the elements and principles.
A portrait uses a shallow depth of field so the face is sharp and the background melts to soft blur — directing all emphasis to the eyes. Side lighting carves out value and form. Every setting is a composition choice, just like a painter's.
