Inaccurate light meter

[McManus]

I'm pretty new to all of this, but why is the light meter so inaccurate indoors? I have a Canon Digital Rebel XT, and even when using flash, when I'm in aperture priority mode with the aperture full open, the shutter speed gets set to something crazy like 1"3. However, if I switch to manual, I can set the aperture speed to 1/60 and the shot will come out perfect. I don't get it, why is the meter so off? (I'm using the 18~55 kit lens, btw)

The meter isn't off, Apature mode exposes for the background not your nearest AF subject.

Apature mode with flash is used primarily for fill flash outdoors since the flash will fill in subject and the automatic shutter speed will be for exposing the rest of the scene properly.

'nuff said. :)

The XT is a pretty strange camera. I have one and can't wait to offload it to go back to Nikon!

Haha Rhys, you really outdid yourself this time. You really are being silly. That you are not able or refuse to understand a camera is your own problem.

And you will be in for a nasty surprise, since a Nikon will be even more complex for you to understand. I can't wait till you "offload" your XT either!

McManus, like timmciglobal said, do not use Aperture priority mode in this way. Just put your camera in P mode and use the wheel to set the aperture you want to use.

10) Why does my camera meter in P and Av modes very differently when I have a flash turned on?

That’s how EOS cameras are designed to work. P, Av, Tv and M modes all meter for flash in different ways. See the section on “EOS flash confusion” for details. Here’s the short version, which repeats some of the points made in previous FAQ questions.

Keep in mind that the camera meters for ambient (existing) light conditions and flash illumination independently.

P (program) mode keeps the shutter speed between 1/60 sec and the maximum flash sync speed your camera can handle. It does this so that you shouldn’t need a tripod, even if light levels are low. It then tries to illuminate the foreground using flash.

Av (aperture priority) and Tv (shutter speed priority) modes set the shutter speed or aperture to expose for the existing light conditions correctly. They then fill in the foreground using flash. If light levels are low you will need a tripod to avoid blur.

M (manual exposure) mode lets you set both aperture and shutter speed to be whatever you want. The camera then automatically controls the illumination of the foreground subject using flash.


Aaaahhhhh.........
