TG-4 Flash Compensation?

[khsjsilver]

I just started diving with the TG-4 and the PT-056 housing without any strobes. One of the adjustments in the camera is Flash Compensation. You can adjust the flash output during underwater shooting. You can set a larger negative value (up to -2.0) to adjust darker, or a larger positive (up to +2.0) to adjust brighter.

Is there any reason why you would always keep the camera set at the brightest adjustment of +2.0? Since I am shooting without a strobe, wouldn't you always want the flash to be as bright as it can be?

Am I missing something?

Thanks,

Ken

If i am correct the flash compensation is used without the housing.
At least that is how I use it with mine.
Exp compensation is used to darken/lighten pix

Interesting question. Think flash "power" versus picture exposure. Picture exposure will take the ambient far-distance light into consideration.Flash power is all about close uplighting.

I found this blog that almost hints at this...

Interesting article with amazing pictures!

The reason people use strobes for underwater is to add additional "flash power". I guess I'm still thinking that upping the Flash Compensation to it's max is a good thing to add as much flash power from the camera as possible, regardless of whether it's meant for the camera without the housing,

Thanks.
