Its funny but I thought by asking the question, I was relating it to what I do, but anyway, glad to see the topic back on track
Funny also, that just tonight, I've got back from photographing a very large commercial building - a huge warehouse/business. And as I switched the timer on to ten seconds, quickly got down from the ladder, and knew that I had 20 seconds of exposure, that I needed to run down the length of the 850 meter building firing the Bron flashhead in my hands at every 100 metres or so, while carrying the 12 kilo battery pack, I had to smile at the comment that photographers didnt need to run fast - well I'm afraid thats what I was trying to say that I do, because at 55, and fast approaching 56, actually I do, which is what I was trying to say Hence why I try and keep as fit as I can
