It seem when I over expose a picture using my 580exII. It seems as if people are amazed at how hi of quality a picture it is. Does anyone get similar experiences?

^^thats the trick for sure, master it and youll be the cahmp.
your exaple is not TOO hot. but try to bounce flash to avoid wall shadows caused by direct flash.

remember shutter speed wont effect flash exposure. also if your flash is set to be real powerfull, you will have to "drag the shutter" to shutter speeds which are to slow for hand held.

if you set your flash to a medium power and set your apurture so that the exposure is good at around 8 ft from subject,(or whatever distance you want) you can use a a shutter speed say around 1/60sec to burn in the backround ambient light, and still hand hold the camera. also try to bounce the flash when ever possible.

point is the less power you give the flash the more you will have to open up the apurture, but the good thing is you will have to drag the shutter less to balance out the ambient light with the flash.

if you dont get what im saying, google it like suggested above.

also a lot of event photogrphers will figgure out propper flash exposure at a given distance at a fixed apurture.
like at f/8 (shutter speed not relivent for this test, only f-stop,flas power and distance matter so set shutter around 1/90sec)
at 4ft 1/16 power
at 6 ft 1/8 power
at 8 ft 1/2 power
at 10 ft 3/4 power. (dont use those numbers, you have to do the testing ahead of time)

when you get to the event location figgure out what the correct shutter speed for the same apurture you did the test with for the AMBIENT LIGHT ONLY.

then always leave your apurture the same, and use the shutter speed that you determined to be correct for the given room with the apurture you tested earlier.

then all you have to do is estimate the distance of your subject and use a cheat sheet to know what power to set your flash for the apurture. so the flash power and the distance of subject will expose the subject perfectly and your predetermined shutter speed will always produce a balnced and proporly exposed backround.

right?
at first tape the flash powers and subject distance cheat sheet to your flash, after a while ditch the cheat sheet.

what's the best way to determine the range v.s. power ratio?

Your question doesn't make sense, I don't even know what you're asking. What are you trying to achieve?

You just experiment by shooting a subject at distance "x" and flash output "y" with a fixed aperture. You choose the "x" and "y". Then chimp the shot to see how it turned out. Make adjustments to your flash output until you nail the correct output/exposure for distance "x". Make a note of the values, and then repeat the process for another distance. At the end of the experiment, you'll have a cheat sheet list of distances and the correct flash output.

Dragging the shutter just means using a longer exposure time which I think sucks since you can always add blur to the image. My goal is to get the sharpest picture possible and go back and add what ever effects possible. This photographer got "lucky" with a shot like this and I can create this shot 100% of the time in Photoshop.

My question was..... If people want over exposure...Do we give it to them at the risk of peers saying it's over exposed.

Why would anyone want over exposure? Why would anyone want a photo that looks like the flash-washed out shot above? I think that if you show them an over exposed shot, and one that is lit well, that preserves the details and has a nice feel to it they'll go with the good image every time.

Furthermore, why would you want to get all of the "creamy goodness" in your photos from photoshop? I mean, does that really make you a photographer, or just an editor?

I would like to think that as well...

Yes I would like to use photoshop at a minimum but I rather "get the shot" and worry about perfecting the dragged out shutter on my 20th wedding.

I was asking what Tiger answered.

so you only practice your camera skills at weddings? how about putting some practice into your photography?
