[Elphel-support] Flash on a two camera system

[Andreas Bean]

Andrey,

I can't set the exposure time even near 67ms. We have difficult lighting
conditions. For example, we have an indoor room with a bright window
where the cam is moving.
Setting the exposure time to 72ms will give me a blurred image of the
window. Anything else may be sharp due to the fact that it is only
lighted for 5ms.
Is the only option to set the exposure time to 5ms and turn the leds on
for 72ms?

Andreas
