I am using a T3i with a Yongnuo YN500EX flash. I find it very very tedius to change the flash power by going to Menu > Flash Control > External flash func. setting > then scrolling wayy down to find the flash power slider. Sometimes when the flash is...

When I use the popup flash in Av, it fires a preflash to use for computing the shutter speed. I can then use the flash exposure compensation to change the flash brightness. I'm assuming the metering is always done with 0 EV even when the flash exposu...

When shooting outside with a bright background, it would be nice to be able to use the popup flash as a fill light (for shadows on a face, etc.). However, the shutter speed is clamped to 1/200 when the popup flash is up, overexposing the scene. Is th...

When in AV mode, I can aim at the point in the scene that I want to lock the exposure for and press the * button (AE Lock). Now say I change my mind and I don't want to lock the exposure - how do I turn off AE Lock? Pressing * again just changes the ...

Sorry, I should have mentioned I am using the Yongnuo YN622 wireless flash trigger to fire the flash. I have the camera flash setting set to Manual. Yea, I would have thought that the flash buttons would override everything else, but I can change the...

Ok, so the idea is that the popup flash is just too weak to bother allowing high speed sync, as say 1/4 of the already low power will not even be noticeable in the scene? As you say though, if my subject is only a couple of feet away, shouldn't the c...

ebiggs1 - After looking through the manual again, it seems like those "preflashes" I was talking about are AF-assist, so perhaps they are not used for determining the flash power? That is, if I turn AF-assist off, I do not see any preflashes. So how ...

Thanks Tim. I think I get the basic idea of thinking of each shot as two exposures. So the camera is good at telling you what the ambient exposure settings should be, and if you think it got it wrong you canuse exposure compensation to adjust. Howeve...

I guess there are two questions: 1) Can you make the pre-flash metering in Av use the flash power set with "flash exposure compensation" to determine the shutter speed? 2) In M, why is there still "exposure compensation"? Since you have to set everyt...
