Anyone have any good tutorials about how to use manual flash, i have a canon 430exii.

I have tried fiddling but it seems to bright even with the power on 1/64, i have also set the zoom length as well so thats not the problem. But all is fine when i put it on TTL. (Want to learn manual as i will be using RF206's which dont surport TTL)

I had a look for a tutorial on google but didnt really come up with much, so if anyone can head me in the right direction will be much appreciated.

Thanks

Exactly what Graham said

Both are great bits of information
 
Use manual mode, f8, ISO 100, 1/125 or 1/160 shutter speed......still too bright?

I got RF602's last week and just started messing around with two Canon Speedlights in manual. You'll get there.

I'd also recommend investing in a copy of the Lightenupandshoot V-book :thumbs::thumbs:

Cheers, having a look through now, looks great, easy to follow as well.

That works, but iam not getting a correct exposure on the meter.
 
602's
 
The camera is indicating the correct exposure for the ambient light because it has no idea what flash exposure is necessary.

In E-TTL, it works out the flash exposure by firing a pre-flash which goes out immediately you press the shutter release, a couple of milliseconds ahead of the main flash. The pre-flash is then measured and the correct power for the main flash pulse is set. This all happens so quickly you can't separate the pre and main flashes by eye - it just looks like one flash.

In manual, there is no pre-flash. You set the power, take a shot, and then adjust the exposure by either altering the flash power, of the f/number or the ISO - or possibly all three. Remember that shutter speed has no effect on the flash exposure but you must not (normally) exceed the camera's max x-sync speed which is 1/200sec on a 450D.

Google focal plane shutter and flash to get a handle on why this is and how it all works together.
