I am retired and recently upgraded my camera to a Canon EOS 1200D so keep my Canon EOS 400D as a spare.
I also have a Samsung ES70 digital "point and shoot" which I use for an instant shot if I don't have my Canon with me. It is this ( rather low spec) camera that I took the "Tunisia Lightning" shots with. I simply filmed the storm and then extract the best frames from the film.
My speciality is scenery,wildlife,the natural world and anything unusual and interesting. Chris Fell, Nearly Famous Photographer.
