In conclusion Mark's new flashgun the Yongnuo YN560-III is a little more powerful than the Vivitar 285s. It has the benefit of much lower power output and although the infra red slave has poor range, the radio slave easily works underground for the quoted 100 metres in a straight line, although does not work far round corners.
Bulbs were giving much better results than flashguns when shooting falling water, and the much higher power output and all round soft light making them great for use in larger chambers and passage. The AG1B bulbs easily giving four times the light output from a Vivitar 285 with the M3B bulbs giving twice that of the AG1Bs.
Light painting was a revelation too and will come into play in suitable locations. Colour balance from the LED lights is a challenge as is the need for the camera to be tripod mounted and having people keep still in the shots.
We will continue to experiment and work to blend different lighting types in the same shots to enhance the overall lighting.
