Question about Canon Speedlite 580EX II TTL Flash
That the camera/flash set-up I use ... there are many variables - iso/metering setting/shutter settings/flash settings .
If it's a flash function problem, try this to isolate it - first, with the diffuser/reflectors tucked into the flash head, and the head straight up, with the flash set in master mode, turn it on and look on the back screen. push the mode button til you see the ETTL in the upper left of the screen .. then press the set button in the center of the dial and the nuber in the center of the display should flash (+0) while the light is flashing, rotate the dial to change the setting (i usually under power by 1/3 stop. Play with the exposures a few times to get the feel for what the EV shifts do to your exposure. generally speaking, for interior low-light, i prefer to bounce off the ceiling (if low ceilinged), if there's too much direct it will give you an uneven and predominantly underexposed image.
if you prees the mode button you will come to the same options for adjusting the output in manual mode, but it will not work with the autoexposure in the camera.
Try playing with the ETTL settings
I think the problem may be that you have somehow altered the power output setting on the 580.
