Further to Thursday’s post, I thought I would brighten your day with some more colour.

You see, sometimes you need to shoot things that are a bit, well, drab. Like this wall – the screen is great but the wall is a bit dull:

Wall with screen

So then, as you also saw two days ago,  I shot it again, this time with two speedlites:

Wall with screen with gels

How was this rainbow effect achieved?

• These two 430EX flashes were fired with TTL using a 580EX on my 1D MkIII.
• They were aimed at the wall, one above the other, aimed in the same direction (good idea from my assistant).
• They were fitted with Honl speedstraps and with a Honl gel each: red for the bottom flash, green for the top one. No other modifiers: other than the gels, they were bare.
• The ratio between red and green was set on the back of the 580EX until I was happy.

That was simple, and I think you will agree it’s a better shot.
