I have a 450D and just bought a 430EXII flash. I have been shooting with my 450D and pretty good at it but when it comes to ext flash settings, I'm still confused. For wedding photography, esp. in a hall where there's no near walls around, what settings do I have to use? High speed sync?Slow sync? Zoom?Exposure comp?
I never plan to buy a diffuser but will try to use a pc of paper to soften the light from flash.
