Re: In just Av exposure mode? or all exposure modes?

Test shots were taken in Full Auto mode and then when I realized something was wrong, I tried Tv mode on the premiss that if I forced the camera to use a 1/60 second exposure maybe it would sort out the aperture. That didn't work.

How did it not work?

If you still got a 1-4 second exposure, it sounds like your camera is malfunctioning.

If the brightness wasn't right, it sounds like the flash is in manual mode.

I can try Manual mode, set 1/60, 5.6 stop then close the stop down until I get a good exposure. But that isn't what I hoped for when I bought the flash.

Make sure the flash is in E-TTL mode. Post two images from that test - one without flash and one with - and we might be able to spot something. (Shoot small JPEGs, then use the "Insert image" button in the toolbar to "Insert image from your computer".)

You might find something among the general tips in the flash section of the unofficial Rebel Talk FAQ.
