FEL and OCF

Does FEL stop fast blinkers during preflash in a off camera setup? Canon IR system.

Thanks.

Yes. Give it about a second between FEL and the shot.

It doesn't matter if it's on or off camera. It works about the same.

Unless the subjects know that your flash is off camera and where, you may catch them looking over towards the flash direction (where the preflash came from) to see who else is taking their picture.

fast blinkers anger me.... few days ago i just gave up on ettl and set them in manual.

Im planning for manual only after i get some radio popper JrX and some RPcubes whenever they get released

Just turn off the red eye reduction.
then fix the red eye in post processing.

most of the editors have good tools just for this.

What difference would that make to the pre-flash?

I think red eye reduction is when you use the internal flash, it flashes half a dozen times to make the pupil contract. I've never seen a Speedlite do that, but i've never turned red eye reduction on either.

I think red eye reduction may MAKE people blink.

My red eye reduction is off. I always thought Red Eye Reduction was some sort of in camera editing not a flash technique.
Who uses the internal flash anyways? Speedlights are high enough that red eye should almost never be an issue.

You're thinking about the focus assist blitz of light from the built-in flash. That's not for red-eye reduction. The red-eye reduction is done via a little light bulb by the side of the lens near the shutter button.

Isnt the little light bulb by the side of the lens the timer for self portraits?
Anyways i got my answer so...
Thanks.

Ah, interesting, I wondered what that was. I just had a play with the 7D and it didn't seem to want to fire, I guess it only fires under certain conditions?

The red-eye reduction beam seems to only turns on if it's been enabled via the menu and when focus has been achieved and locked (and, of course, the built-in flash has to be popped up and ready). I always have my red-eye reduction disabled so there's a chance I could be wrong.

I turned it on and locked focus, but had a speedlite on the hotshoe that wasn't turned on. Maybe i'll go read the manual.... nah

Did you miss the part about the built-in flash needing to be popped up and ready?
