Thanks again Denny Boy - so, what is an off camera flash - is it a flash that is not connected to the camera? Sorry to sound so dumb but I am still getting to grips with all that 'technical' stuff. I must admit I read the box wrong - thought it meant no flash at all!! (I only have a flash that is attached to the camera just above the lens (not ideal I know, but then it is a Fuji S6500fd).
