Make it
Choose a nearby stationary object and two lighting conditions already available, such as a room light on and off. You can also wait for daylight to change; waiting time is extra.
- 1
Place your device comfortably and take a photo of the object in the current light.
- 2
Keep the object still. Change an existing room light if easily accessible, or return when the daylight changes.
- 3
Take a second photo from approximately the same position.
- 4
Compare one shadow, one edge, and one color. Keep the pair as a light study.
Short on energy? Compare the object by eye in two lighting conditions.
A good place to stop: Two photos and one noticed difference complete the study.
Make it work for you: Ask someone to operate an out-of-reach light, or wait for daylight instead. Keep device handling brief.
Another route: Photograph the same object on a bright day and a cloudy day.
