Thanks for the comments folks
@ E. S Charlie - The Silver reflector was invaluable on the day, it was held only just out of shot and reasonably close to Rach to fill in shadow and help show the shine.
On a day like that one, fill flash did nothing or just helped one tiny spot, really needed the reflector to cover more area and pray the spot metering picked the right spot I wanted.
Normally I'd shoot in full manual but gave Av priority a go this time around so I could change position, angle and distance from the model and not have to re-check setting each move. The reflector holders (nneded two people to hold it steady in the wind we had) really got a work-out staying in close and getting the light where I wanted it!
