Hello there,

When filming underwater, how do you read exposure(can you take spot readings?) Is there an underwater lightmeter?


warm ones

I have seen lightmeters in Housings, although it is yet one other thing to fumble with. You may want to depend on an average reading, as the light does flatten out a fet feet down. 30 Feet down even in clear ocean water you have probaly lot a couple of stops.

Of ocurse you loose the reds and yellows first, so often the exposure is based on the artificial light that you carry with you. AT 90 fet you may as well just shoot black and white and project it with a blue filter otherwise.
