Standard white balance modes (As Shot, Daylight, Auto, Custom) can be cycled through using Menu–
Adjust–Toggle White Balance (or by pressing W key on the keyboard).
If the RAW file contains a list of standard white balances in its EXIF data, this list will be shown in the
drop-down menu (between Auto and UniWB). If there is no list of white balances in the file, then the
generic table for the camera model that took the shot will be used instead.
If two neighboring files are taken with one camera, and a mode to preserve white balance when
moving between files is active (Preferences – White Balance – White balance for next file (same
camera), see detailed description below), but the two above-listed files contain different balance
preset lists (for example, one file is in the camera’s original RAW format, while the other is converted
to DNG), then:

If possible, the setting (preset) with the same name is preserved.

If no such preset exists, then the “White balance for the next file (another camera)” is used,
meaning that the program assumes that if the lists of white balances are very different
between two files, then the camera must have been changed.
Controlling which White Balance will be Used when Opening a File
When opening the next file the White Balance is set in accordance to the settings in Preferences–
White Balance:

White Balance for next file (same camera) – sets the white balance mode when opening a file
coming from the same camera model as the current file is. Choices here are: Same as
previous, As Shot, Daylight, Auto, and Tungsten.

White Balance for next file (another camera) – sets the white balance mode when opening a
file coming from a different camera model. The choice of “Same as previous” normally does
not fit here – all other choices are the same as for the previous.

Keep Custom WB for next file (same camera) – instructs FastRawViewer if the current white
balance coefficients should be applied to the next file coming from the same camera model.
Setting White Balance by “ Click-Gray ” Method
To set the white balance using an arbitrary area of the image as a reference, use Alt-left mouse click.
The size of the area which is evaluated to calculate the white balance can be set through Preferences
– White Balance – WB Sampler size
Coefficients will be calculated for the chosen area so as to make whatever is “clicked” gray. The
image will change its look (automatically calculated exposure adjustment may change as well).
If the correct color temperature can be calculated with the given coefficients, then it will be displayed
on the button for the manual white balance adjustment.
