Thanks that's much appreciated, I normally leave iso to auto but use manual settings on the camera.
I do have a tripod but was just going to do it free hand.
Do you have any idea what power setting to use the flash to fill the faces or would that depend on the lighting on the day, just don't want to keep adjusting and altering the setting while I'm in the shoot, I will practice in the garden with my son before hand though.
Thanks
