OK, When I am taking beach photos (sun behind subject) and going to use fill flash at 2 stops under ambient. Which way do you face to take reading, I am assuming that you would hold meter same way your subject would be facing to get the ambient reading but want to know if anyone does it differant.

I want the background to be clear and well exposed I suppose you could hold the meter flat horizonly. I have a chance to shoot on the beach this week and hoping to get some imput before I go.

I would take a camera meter reading of the sky adjacent to but not including the sun to get an ambient light reading. Then dial in the amount of fill flash you want. Usually -1 to -1 2/3 FEC.

It really depends on the type of meter you are using. An ambient meter with a flat disk instead of a dome acts differently. A reflected meter is used differently. A in camera meter can operate in multiple ways too...

Sounds like you have an ambient meter. I have not used one of those, but generally you need to meter your light sources which would be pointing to the sun from your subjects point of view. Set your camera to expose for the light source reading. Use the flash or reflector to bring up the shadows (if needed).

Re: Shooting on the beach.
Sand is very harmful to the inner working of both camera and lens. Is your camera and lenses sealed against sand (most are not)? A single gust of wind can run you hundreds of dollars getting the sand cleaned out and any damaged gearing replaced. Ensure the camera bag is grit free too.
