A shoot-through umbrella, on a stand with an adapter bracket, works well. £30? Make a reflector out of a sheet of card and kitchen foil. If you want the pure white background look, you will need another light, probably two. You know that your 60D acts as a master auto-flash controller for the 430 as a remote slave? Great feature
But without spending a bean, get yourself a tame subject and have a play around. You need a room with a normal height white ceiling, and light coloured walls. Draw the curtains if it's daylight. And you need a bounce card because Canon has unhelpfully forgotten to fit one to the 430 - just a business card and a rubber band will do, see here
www.abetterbouncecard.com Put the 430 on camera, without the bounce card, in E-TTL mode. Camera on manual, 1/200sec at f/5.6, high ISO800 for this test, just to make sure you don't run out of flash power and get under exposure (bounce flash uses a lot of power).
- Stand in front of the subject and, just for comparison purposes, point the flash straight at the subject. Note the harsh shadows.
- Now point the flash straight up at the ceiling. Note the soft shadows, because the ceiling has now become a much bigger, and therefore much softer light source.
- Now fit the bounce card, and do the same thing - straight up. Note the shadows under eyes and chin have been lifted, and there's a nice sparkle in the eyes.
- Same again, but angle the flash head foward two or three clicks. Note how the light coming from the little bounce card has got brighter.
- Take off the bounce card, and turn the flash compeletely around so it is firing straight at the wall behind you. See how you like that.
- Then turn the flash head so that it is behind and to one side.
- Then up a bit so that it is pointing half at the wall and half at the ceiling.
- Then point it at the side wall. Note how the direction of the shadows changes, and maybe put the reflector on the shadow side to lighten them.
Now you're away

There are loads of accessories available to help with this stuff, but they mostly all work in pretty much the same way as a simple bounce card - using the ceiling/wall as the main light source, with a dash of fill-in from the card. Works great, and once you get the hang of it, you can turn most social environments into something that looks pretty good.
