I have an olympus C760 digital camera and was thinking of geting an underwater case for snorkelling and have realised that the inbuilt popup flash cannot be used with the housing.
Is a flash necessary for this type of underwater photography.
The flash accessory costs a LOT!
Thanks
A flash will always help in any low light situation. If you're going to be doing a lot of underwater work, you might want to go ahead an bite the bullet and get the flash unit.
If you're only going to be doing a small amount of underwater shooting, then you can probably get by with available light, just rember, the deep you go, the greater the light drop off. You might be able to see okay, but the sensor on you camera might not be able to see at all.
Do a little experimentation and see at what depth you can successfully shoot with available light.
