Testing image colours with flash

For testing image colours with flash, take an image of the target, which contains something white. You should
take the image in total darkness and from less than 1m range.
If the white target appears to be white, the flash is working correctly. However, remember that there is some
variation in the flash colour from module to module. For more information, see section "Colour difference
between different modules" in "Flash LED and image taking conditions".

Testing flash power

For testing flash power, take an image with the flash in total darkness (ambient light level < 1 lux) from a target
about 80cm – 1m away.
If the flash is working normally with adequate power level, the image is correctly exposed from 80cm – 1m
distances.
Remember that the brightness level in the corners is always less than in the center of the image because of
camera and flash optics.
