Can someone explain to me on how to use this as the instructions say for auto mode set to ETTL ok in P mode the shutter speed always stays at 1/60 now when i set the mode to TV, AV, OR M, i get really low slow shutter speeds, does anybody know any links to where it explains it better or maybe someone in here can thanks

Hercules-

Here is a copy of a post that I posted over in the Canon Digicam Folder:

Thanks John, for coming to my rescue. The Canon S-5 arrived today, and I am charging batteries right now as I write this post. In as much as Hercules just got a Canon EOS 450D, I am going to expand the Canon EX-430 Flash Tutorial to include the Canon G-7 & G-9, the S-5 and the XT I own XT should work very similiar to the 450D, and that will help out Hercules.

This is a really busy day, so I will probably get started in earnest tomorrow (13 August). I will be posting it over in the Canon Digicam Folder, because Canon S-5 folks are usually the biggest number in the group. And yes, please take a good look at John's Gallery. He went through the first cycle of this Flash Tutorial that I did in the Spring 0f 2007.

You need to set to "high-speed" sync!

Bear in mind though that as the shutter speed increases the flash output decreases exponentially so if your goal is to have more light then this wouldn't work...
-> Sometime it's better to have a slower shutter speed to have maximum flash power output as the flash pulse itself will freeze the motion regardless of shutter speed!

Thanks NHL, i think i am starting to understand the 430EX flash, as i was a little mixed up, i thought no matter what kind of lighting you had in a room that the shutter speed no matter what could be set at 1/125th or even 1/200th of a second and still have the exposure level indicator right in the middle:?, so what you are telling me is that even if the exposure level indicator is -1 or -2 and not in the middle that the flash will freeze the motion and not have a blurred image right?

Exactly!
You got it, the flash will bring the exposure level indicator back to the middle when you release the shutter...

The -1, -2 EV scale let you control how much ambient light (i.e. background) will be blend with your flash: At -1 more background will show than at -2 for example.
You're also not limited to the shutter speed - In manual you can change the aperture while the flash still remain on auto (i.e. it will bring the exposure correctly back to the center) and leave the shutter to your desired speed!

Ok thanks you've been helpful just one more thing to set the 430EX to auto zoom do i just set ETTL and nothing else because when i do that the zoom always shows -- and does nothing when zooming thanks

What zoom lens do you use?
-> The 430EX accounts for cropped camera so it might not adjust its setting as much

The automatic zoom always revert back to default Auto-zoom so unless you force it with the manual button, I don't think that would be an issue...
