Still pushing myself with this flash and portrature thing!
Took this earlier, took a photo without flash, metered, wacked in my flashgun where I felt it should go, and put my camera flash onto the same power level (Though i was further away, so it was just acting as fill)
So effectively 3 lights, the sunlight on the rear right, flash gun just off camera left resting at eye level on a cross bar (Wide angle converter on to throw around the light) and the on camera flash as fill trying to get some light below the cap on the other side.
I did decide to underexpose the ambient a tiny bit to try and make it pop.
Despite over exposing parts (Though Ive always been given the impression that this is forgivable in portraits) and wishing I had another light or a relector on a stand to fill in those shadows, I dont think its too bad.
