Digital Sensor

APS-H

Bulb

Special shutter speed at which the shutter will continue to open during the shutter button is pressed. Typically, this feature only found on digital SLRs and allows photographers to expose the image to many minutes long.

CCD (Charged Coupled Device)

This type of digital sensor that functions convert light into digital signals. CCD technology has evolved long enough to have undergone many innovations.

CMOS (Complimentary Metal-Oxide Semiconducto)

The type of digital sensor befungsi convert light into digital signals. CMOS more power efficient and cheaper production. However, technology is not as advanced CCD technology.

Continuous Drive

Shooting mode where the camera takes a series of pictures during the shutter button is pressed. Average speed is 3 fps, while the latest digital SLR is that reached 11 fps.

DOF (Depth of Field)

GN (Guide Number)

Figures showing the strength of the flash, the bigger, stronger.
