RGB (red/green/blue) value. Color value of a pixel. You can identify the RGB value of a pixel in the advanced information display in Capture mode. You can also display a histogram of values for all RGB channels in a picture. Shutter speed. The length of exposure time for the picture. Darker conditions require slower shutter speeds, while moving subjects require faster shutter speeds. The shutter speed on your HP pocket camera ranges from 1/2 second (slowest) to 1/8000 second (fastest). Spot metering. A way to override center-weighted metering, the camera's default method of measuring the brightness of a picture. Use spot metering to identify the part of a picture that you want the light meter to use to calculate exposure-for example, if the subject of a picture is much brighter or much darker than its surroundings, or if the subject is not centered in the frame. 54 hp pocket camera
