Further tip , do not gaze longingly at the fishes head with a baleful look on your face . Don't know why but I always find this vaguely disturbing . Much prefer a snap with big cheesy grin on the captors face

Gazing longinly at the fish usually tells you its an ex carper,they all seem to do this,a bit strange

The post above regarding intensity of an energy source relative to the subject distance from the source is incorrect. The "Inverse square rule" applies which is a basic principal in physics. More here; https://energyeducation.ca/encyclopedia/Inverse_square_law
My apologies, you are mostly correct, I would just always think about the remaining intensity over a given area. The light has not been lost it has just become lower in its intensity due to a larger area of coverage.Taken from the link above; "If the source is 2x as far away, it's 1/4 as much exposure." Therefore it has lost 3/4 of its power if the distance is doubled.
In layman's terms the if the optimum power output of a flashgun gives best results at 2 metres from the subject, if you half that distance to 1 metre the amount of light on the subject will be four times as much and if you doubled the distance to 4 metres between the flash and subject the amount of light illuminating the subject would be a quarter of the optimum. That is why the scenery behind subjects always looks very dark and anything in front of the subject will be bleached out.
On cameras with manual exposure options you can adjust the aperture and / or shutter speed to compensate for the power of the flashgun, bt tht needs a modicum of photographic knowledge.
Paul as you're/were a professional I would be interested in your reasons why you don't think tripods are a good idea. I've been using them for years , but to be honest my results using self takes are of a dubious quality to say the least. I'd be very interested in improving my results. I use a Canon G10 (flip screen) . Not an SLR.It is second nature to me! I was a professional photographer for nearly forty years. First eight years using Sinar mono rail cameras photographing fine art and architecture and the rest as a senior medical photographer in orthopaedics. Never take a camera with me now.
