Hi Folks.
I have just been watching a film about the DH Mosquito, one of my favourite aircraft. One part of it was about doing night time flash photo reconnaissance using a flash of 700 million candle power, (May have been several hundred million, iffy sound right as they gave the power). Any idea what the guide number for that would be?
Film here for those interested. Time code 23:30 for the bit about the flash.

Cheers, Graham.

Hi Graham, not being an aircraft enthusiast I almost didn't bother looking. This is absolutely amazing and well worth passing on! Oh, the flash - have no idea. :unsure:
