Phantom Flex4K Manual
Optionally, the user can select common white balance
settings of 3200, 4300 and 5600, or manually adjust
the Color Temperature (Kelvin) for the red and blue
components of white balance, and Color Compensation
(CC) for the magenta and green components of the white
balance.
Exposure Index
EI (Exposure Index) is a reference value for the
apparent light sensitivity determined by the current
image processing settings. The available presets range
from an EI of 250 through 1250.
EI values are controlled with preset tone curves. Gamma,
Gain, Toe, and other image settings also have an effect.
The value on top represents the combined EI value, and
that is the value to use when determining lighting and
exposure settings.
Clicking on the Gamma, Gain and Toe soft-buttons will
bring you to the image processing menu, where those
values can be adjusted or set back to their defaults.
When the camera’s video output is set to ‘Log’ mode,
the EI can not be adjusted, and must be used as a
reference only.
