Tip of the Day: In Terms of Photography

Complementary Metal Oxide Semiconductor (CMOS)Also known as CMOS sensor. And integrated circuit, or IC chip, that is a type of microprocessor. CMOS is used in digital photography as a type of image sensor chip. Its advantages include using less power, which produces less heat, and making less noise than other types of microprocessors and image sensors.

Learning photography involves more than learning shooting and compositional skills. It can often feel like you have to learn an entirely new language. Here’s just a few terms and what they mean:

Complementary Metal Oxide Semiconductor (CMOS)
Also known as CMOS sensor. And integrated circuit, or IC chip, that is a type of microprocessor. CMOS is used in digital photography as a type of image sensor chip. Its advantages include using less power, which produces less heat, and making less noise than other types of microprocessors and image sensors.

Flash, Slave
A flash that detects the flash of another flash and is thus triggered to fire (also called a slave flash).

Fringing
A discoloration around the edge of a digital image. Purple fringing is caused by chromatic aberration. White fringing is caused by over-sharpening.

Gretag Macbeth color checker chart
Also called MacBeth color chart. The standard for measuring and comparing colors in photography, printing, and graphic arts. Gretag Macbeth is a printed chart with different colors and different gray scale levels. There are a total of 24 squares, including pure white, pure black, and four levels of gray in between.
