on d70 to measure white balance,press wb button briefly,then press the button until the PRE iconin the control panel starts to flash. a blinking PRE willalso appear inthe control panel and the viewfinder.

Frame the reference object/white card/ so that it fills the viewfinder and press the shutter-release button all the way down.the camera will measure a value for white balance and use this balance when preset white balance is selected.no photo will be recorded,white balance can be measured accurately when the camers is not in focus.

if the camera was able to measure a value for white balance,GOOD will flash in control panel,the viewfinder will show Gd. .to return to shooting mode,press shutter-release half way,or wait until exposure meters off.

if lighting is too dark or too bright,the camera will flash no Gd.


repeat each time you want to set custom,i carry a whiti card at all times.i change it as much as i change my shutter speed.

this is how i do it,
