In selecting high speed sync on my 430EX (and also on a 430EXii) I press the high speed sync button so that the high speed sync icon is shown in the flash unit LCD panel. According to page 16 of the 430EX and 430EXii manuals, you "check to see that the high peed sync icon is shown in the viewfinder."

However, "If you set a shutter speed that is the same or slower than the camera's maximum flash sync speed the (high speed sync icon) will not be displayed in the viewfinder."

My question is: if the camera is set at a shutter speed that is the same or slower than the camera's maximum flash sync speed and the HSS icon is not being shown in the camera viewfinder, is the camera firing in HSS mode or has it reverted to standard sync?

The standard sync will, of course, provide full power firing while the multiple bursts in HSS will provide reduced power.

I think it will go back to normal sync with full power if you are below the camera fastest sync speed, usually 1/250

^^^^ That's right. There is absolutely no purpose to high speed sync if you are at or below the camera's normal sync speed.

Keep reading on page 16 of the 430ex manual and it says this.
"If you set a shutter speed that is the same or slower than the camera’s
maximum flash sync speed, <F> wil not be displayed in the viewfinder."
The gray note boxes of Canon manuals usually have the best info in them.

I certainly do not want to argue the merits of the Canon Manual but, this statement is quite ambiguous in that it only states that the HSS icon "will not be displayed" when the shutter speed is at or below the maximum sync speed. It doesn't say anything about the whether the camera reverts to normal sync.

However, I assume that this is what the writer of the manual wanted to say, and probably assumed that he had said but, did not. However I don't like being forced to assume anything because "assume" often makes an "Ass" out of "u" and "me"

In this case, why not always keep the flash in HSS sync and allow it to revert to normal sync whenever you select a speed at or under the maximum sync speed and have it revert automatically ot HSS whenever you elect to choose a speed faster than the maximum camera sync speed. Piggy-backing on that notion, why have HSS as selectable at all. Simply let the camera decide which to select depending on the shutter speed selected...

^^^ You could do that, I suppose. However HSS depletes your batteries rapidly and reduces the actual flash output the higher the shutter speed, so you will have to use Flash Exposure Compensation if you are shooting at eg. 1/2000 sec. Joe McNally gave a nice demo of this on the Flashbus tour. Personally, I used HSS a few times to see what it could do, but I have never used it otherwise.

I have wondered the same. When I use the Pocket Wizards this all happens automatically, but I have been caught a few times when I turned on an on-camera fill flash and the camera reverted to 1/200 without my realizing it.

Sorry but even if you set HSS on the flash, you still cant shoot max shutter speed on your camera. the most i can shoot with HSS on is 400/1
