No matter how cold, or how late or how windy you will almost alway find fishers on our local jetties.
I once heard what I was told was an ancient Polynesian saying that 'the gods do not take from a man's life the time spent fishing'. It would seem this old couple might just know something.
I love natural light night photography because images taken this way really draw me to the place and the occasion. They are of course quite challenging however to do well. Working with low light, long exposures and moving images is simply is all part of the fun and sometime a little luck works its magic as well.
A very sturdy tripod is mandatory for long exposures and I cannot stress how important this really is. A flimsy tripod will wobble in the slightest breeze blurring long exposure images. I have even seen some enthusiasts use tripods made of steel and concrete for extreme telephoto astronomical photography where stability really matters.
