ST-E2 Speedlite Transmitter help

[HKFEVER]

Setting on the ST-E2 is easy, but should I set the 1DsMKII in AV fill flash or P auto?

I found setting in AV yeild better lighting for the background. Why?:oops:

[Todd Jacobsen]

In Program AE, the camera determines whether it should use the Flash for PRIMARY lighting or fill. This is based off of the exposure setting (metered, spot, partial). In Av, the camera ONLY provides an exposure reading for flash fill.

On top of what Todd said, let me add that it doesn't have anything to do with the STE2 unit.

The STE2 unit is only the wireless link between the camera and the flash, and it has nothing to do with metering, flash, or any of that. It might possibly assist with autofocus.

We should try to get the original poster a scholarship to attend the Scott Berger Photo flash photography seminar. I understand that Scott has a whole team of flash experts who tutor Canonites in this fine technology. In fact, somebody said just the other day that Scott was down at Central Park being a flasher.

The reason AV yields better lighting for the background (for low light environments) is because in AV mode the camera will meter for the ambient light. It will determine the shutter speed to get the proper ambient light exposure for the aperture that you have selected. If the flash is on in Av mode, the camera will usually compensate for that by decreasing the exposure a tad to account for the flash.

In P mode, the minimum shutter speed the camera will use when the flash is attached is 1/60 second. The aperture selected will usually be the widest aperture available on the lens or as wide as needed to get optimal exposure from the flash. But in low light conditions, these settings are usually not enough to get a proper ambient light exposure. That is the reason why most shots in P mode have a darker background than those shot in Av mode.

However, under normal lighting that will give proper exposure in P mode, both P and Av should yield almost similar results when a flash is used.

I try to personally answer as many flash questions as I can. Leo usually beats me to it with the correct answer. I feel so unneeded! :cry:

Oh, man. Now I feel bad. I hate to see a grown man cry. So I'm going to shut up now and let Scott have his turn. I'll go sit in the corner and what for my turn again. :o
