Dont take any notice of those buggers above, I just ignore them. Heb will be throwing his half penny worth in next I expect.
Flash guns.
I use any old thing I can lay hands on, you dont need dedication etc. And power is not really a consideration using the RCU, you just fire the thing over and over.
The flats were taken on multiple exposures, by the way. But I have to make sure that I am standing somewhere where the light from the following flashes wont make me transparent. Also, find hiding places round corners and from behind pack walls etc to fire the follow up flashes, otherwise there would be several of me in the picture.
I think that one RF is enough in the mining scene, more than one and everyone would pack it in and take up Morris Dancing instead.
