This is the start of my ?4 ring flash

Right, ok. It's going to be used for macro shots mainly, it's not big enough for portraits but if I can get great shots doing this I'll work out a way to make a LED light ring that's bigger rather than fork out for an Orbis one.

This cost me ?3 on ebay and it's an "ufo camping light". Excellent find!
