Use subjective when you're talking about an opinion or feeling that is based on an individual's perspective or preferences. Use objective when you're talking about something—like an assessment, decision, or report—that's unbiased and based solely on the observable or verifiable facts.

You can find the Golden Ratio when you divide a line into two parts and the longer part (a) divided by the smaller part (b) is equal to the sum of (a) + (b) divided by (a), which both equal 1.618. This formula can help you when creating shapes, logos, layouts, and more.

Diffused light, or soft light, is light that's filtered by something. Sunlight through a sheer curtain is diffused. Light from behind a lampshade is diffused compared to the direct light of a bare bulb. The lampshade softens and scatters the light.

In photography, a tripod is a portable device used to support, stabilize and elevate a camera, a flash unit, or other videographic or observational/measuring equipment. All photographic tripods have three legs and a mounting head to couple with a camera.

A monopod, also called a unipod, is a single staff or pole used to help support cameras, binoculars, rifles or other precision instruments in the field.

Partial metering covers only the centre 6.2% of the frame in the viewfinder, thus providing precise metering only for the subject. When the background is brighter than the subject due to reasons like back lighting, this metering mode is particularly useful.
