Nikon 1 J1, 27528, 27534 manual 123, DAuto Power Off, DPreset White Balance, AColor Temperature

DAuto Power Off

White balance measurement will end without a new value being acquired if no operations are performed for the time selected for Auto power off in the setup menu (0 151; the default is 30 s).

DPreset White Balance

The camera can store only one value for preset white balance at a time; the existing value will be replaced when a new value is measured. Note that exposure is automatically increased by 1 EV when measuring white balance; if M Manual is selected for Exposure mode, adjust exposure so that the exposure indicator shows ±0 (0 111).

AColor Temperature

The perceived color of a light source varies with the viewer and other conditions. Color temperature is an objective measure of the color of a light source, defined with reference to the temperature to which an object would have to be heated to radiate light in the same wave- lengths. While light sources with a color temperature in the neighbor- hood of 5,000–5,500 K appear white, light sources with a lower color temperature, such as incandescent light bulbs, appear slightly yellow or red. Light sources with a higher color temperature appear tinged with blue. The camera white balance options are adapted to the follow- ing color temperatures:

•Sodium-vapor lamps: 2,700 K

•J(incandescent)/ Warm-white fluorescent: 3,000 K

•White fluorescent: 3,700 K

•ICool-white fluorescent: 4,200 K

•Day white fluorescent: 5,000 K

•H(direct sunlight): 5,200 K

•N(flash): 5,400 K

•G(cloudy): 6,000 K

•Daylight fluorescent: 6,500 K

•Mercury-vapor lamps: 7,200 K

•M(shade): 8,000 K
