How to adjust the white balance of D80 camera on location?

The white balance must be adjusted with a gray card with a concentration of 18%.

1. Turn on the camera, set it to any shooting mode, dial the camera master wheel to set the white balance to the position of the LCD screen PRE, and keep pressing WB key for more than 3 seconds. At this point, the screen Pre starts flashing, prompting that manual white balance setting can be performed. Now aim the lens at the gray card and press the shutter. If the measurement is successful, the LCD will display Gd. Jg9 Dongguan Product Photography-Advertising Photography -769 Photography Design

2. When measuring the gray value of the gray card, it should be consistent with the light source and illumination angle of the photographed scene. The distance between the lens and the gray card should be kept above 15 cm, and the gray card should fill the whole picture as much as possible to avoid any projection.

3. The process of measuring gray balance has nothing to do with the focal length of the lens. At this time, AF autofocus can be converted into MF manual focusing, and the focal length of the lens can be adjusted to infinity. The purpose is to make the gray card more fuzzy and soft. The exposure compensation function may interfere with the measurement data, so it is recommended to turn off the exposure compensation function.

About grey card

Grey card is the benchmark for accurately detecting exposure. Photos with rich layers and saturated colors come from accurate exposure. If the light of the shooting scene is too bright or too dark, it may lead to exposure deviation.

The gray card can balance the scene with complex light into 18% neutral gray. By recording the reflected light of the gray card with an exposure meter, you can get an accurate exposure value! 18% gray card can not only measure the exposure of the camera, but also adjust the color balance and restore the true color by controlling the gray balance in digital photography.

Exposure value of gray card can be measured by hand-held exposure meter, TTL SLR camera, digital camera and paraxial camera by photometry. Using grey cards is the guarantee of taking high-quality photos and a necessary tool for photographers!
