external flash question
I got an external flash (430EX) not long ago and just wondering what everyone does.Do you guys normally leave it on?.

If I do leave it on, the next question might sound a bit stupid, what do I do if I dont want flash on my shot? Do I just turn it off or is there a setting that I change. I use a Canon 400D..

Also, Im reading this article about having slave and master flash. And the author mentioned that he disabled the flash on his camera but allowed it to trigger the slave. How did he doit (disable the output but still trigger because that would have meant that the flash was ON - which is why I had my first question..

Thanks..

PS. The author of the article Im reading is using a 580EX flash. Which is a higher end version of the one I have..

PPS. I've read the manual but doesnt say anything about my question...

Yes, just turn it off when you don't need it..

As far as I know you need an external flash acting as a master to use the 430 as a slave - the 580EXII would be the one for that..

No - never have it on (on the camera that is). I use a flash bracket and the Canon TTL flash cord to mount the flash off the camera..

Yes. No flash OFF button on the 400D like what I have on each of my non-DSLR cameras..

As other poster mentioned. The 430EX is a slave-type flash (to a Canon master flash) and thus can't control other Canon flashes. Need a 550EX (dis-continued) or 580EX or ST-E2 Transmitter or maybe something else I'm not aware of that can act as a master controlling flash..

Canon ST-E2 Transmitter.

Well generally speaking, turn the flash unit off. There's a few little complications and variations, though, and the details will vary from camera to camera. You might like to check out how it works in different situations with your particular camera and flash. For example:.

You don't HAVE to turn the flash off. You can change the flash setting on the camera. Your camera will usually a number of flash settings, including plain ol' "off". But these settings are generally not available in Auto mode, or any of the Scene modes - only when you are using the P, S, A or M modes. In the Auto and scene modes, the camera decides for itself whether the flash is to be operated or not. In P, S, A and M the photographer decides.



If the flash setting on the camera is "off" it doesn't matter whether the external flash unit itself is on or off - the camera won't use it..

HOWEVER. If the camera is in Auto mode, and the external flash unit is turned off, then the camera will (probably) try to use the internal flash. Because in Auto mode, if the camera decides it wants to use the flash, then that's it..

So what happens on my D80, for example, is that in Auto mode, with the external flash attached but off, then the interna flash pops up (and strikes against the bottom of the external flash, which is overhanging). But if the external flash is turned on, the camera recognises this and uses it in preference to the internal flash..

It's a bit tricky at first, but all pretty logical once you think it through..

Can't help you with master/slave stuff, sorry..

Congratulations..

Yes or no, it really depends on where and what I'm shooting. If you are shooting in anything but open sunlight, the flash *can* help. Even then, it *may* help. the trick is learning how and when to using the flash in bright light. In any other situation, I will usually have it on..

You have to turn it off. With a little practice, and once your hands learn where to go, it takes minimal time to turn it on or off as needed..

Also, Im reading this article about having slave and master flash.And the author mentioned that he disabled the flash on his camera butallowed it to trigger the slave.

This is a custom setting in the 580EX/580EXII flashes. The flash only emits the control signals for the slave(s), it does not add to the exposure. It may also be available with the 550EX, not sure on that one. You can't do this with the 430EX, as it is not a master flash..

Thanks..

Your welcome..

At least you read the manual. That's farther than a lot of people go! I have both a 580EX and a 580EXII in my bag, and I have the manuals for both in the bag as well. Never overlook the power of these 4 letters.....

RTFM..

It's saved my behind more than once!.

FYI the 550EX behaves in essentially the same way as the 580EX series, in terms of it's master control functionality with the likes of a 420/430EX, and/or additional 550EXs. As with the 580, it also goes one step further than the ST-E2 controller in terms of the remote control operations it can perform. Apart from being a bit more bulky, a 550 really gives away nothing significant to a 580..
