WB Button (White Balance)

Nikon D7000 WB (white balance) buttonExplanation: The white balance is a correction of color rendition to make the picture from the camera sensor as similar to the perception by human eyes as possible.

While pushing the WB button you can choose the type of white balance with the main command dial at the back, as indicated by the symbols at the bottom of the LCD display:

A for an automatic adjustment where the camera assesses the light situation itself

      for a correction specific to the indicated type of light:

  • light bulb
  • flourescent lamp
  • direct sunlight
  • flashlight
  • daylight with overcast sky
  • daylight in the shade

K for direct choice of a color temperature (more details further down)

PRE for a manual white balance („preset“) for which you point the camera to a grey or white surface and instruct her to use this as a reference for neutral color.

The steps to use it are:

  • Release the WB button and push it again until the symbol PRE starts blinking.
  • Point the camera to a neutral grey or white subject so that it fills the whole viewfinder.
  • Push the shutter release button. This will not take a picture but only record information for white balance.
  • If you see a confirmation „good“ on the LCD display and „GD“ in the viewfinder the white balance was successful.
    If not you have to repeat the steps.

Note: Such a manual white balance is actually used only if you also the the display „d-0“ on the LCD display. See more details further down.

With the sub command dial at the front and the WB button pressed you can do the following settings that vary with the type of white balance:

A and       : The sub-command dial at the front allows a fine tuning of the white balance. Values A1 to A6 will make your pictures warmer (A for „amber“), B1 to B6 cooler (B for „blue“).

K : The front command dial changes the colour temperature.

  • 52000 K is the standard value for daylight,
  • lower values are for warmer (orange) light and will cause a correction towards cooler (blue) colors,
  • with higher temperatures it is the other way round.

PRE: The front command dial lets you choose between five white balance settings that you can create yourself, the active one is indicated by the numbering d-0 to d-4.

A new manual white balance is always stored as d-0, you can copy it from there to d-1 to d-4 with the shooting menu White balance. You can even assign clear text names there.

Tips: One of the really important settings! Good color rendition is crucial for good photos.

My rules of thumb and recommendations are:

  • Subjects in direct sunlight are no problem, leave the white balance on A for automatic.
  • On cloudy days and in the shade I use a manual white balance with the corresponding symbols for warmer colors.
  • Under electric light with bulbs the automatic white balance is also good.
  • If you want really accurate color rendition you are on the safe side with the manual white balance. You can buy special grey cards as reference subjects for this purpose but a white sheet of paper, a white T-shirt or something similar also does the trick.

The color changes with the fine tuning A1-6 and B1-6 are subtle but visible.Those who want to define white balance exactly and already at the time of shooting will need them. But such fine corrections are no problem in later image processing.

But color rendition is also a matter of your personal taste – so please do experiment with these settings and watch which ones you like.

And note: The shooting menu White balance offers two additional fine tunings that you cannot access when using the WB button, among them one for green color cast.
