Didn't know what to do today, there was a nice sunset on the way home but... nah.

So, got home and chucked a flash-gun into a waste-paper basket. Return to the flash with the red filter then a bit of fettling in PS to change the colour. The filter doesn't quite cover the whole of the flash-head, I think that's why some of it was different enough to turn a different colour.

Oooh - great alternative title from Gail - pinched it :-))
