Calling EJW...
What was the make and model of that nifty little yellow video camera you were using in Cwmorthin the other weekend?
Have just got around to looking at the video links you posted and was well impressed with the light. I've tried two helmet cams before now but the cheaper ones are CMOS sensors and they don't like low light level.
Were they lit with your headtorch or that Lupine lamp?
my orders are to sit here and watch the world go by
