Very nice work.

And there was a little green flash at the end: does anyone know if that was for real or a trick of the camera?

The green tinge on the top of the setting sun is a real optical effect caused by refraction and under the right conditions can flare for a second just after the sun has set. .http://www.wikihow.com/S ee-the-Green-Flash

It is real, I saw two of them with my own eyes. In fact the ones I saw were much more intense. They are best viewed when the sun sets at sea so nothing blocks the horizon. The effect is due to refraction of the light by the atmosphere just like in a prism.

Yes - that's the "green flash" I'm wondering about. I guess a more precise question is:

Is the green flash we see on this video an objective burst of radiation at a particular wavelength that has been captured faithfully - or is the green flash phenomenon a subjective experience (like complementary-colour after-image) and the flash we see on the video has been produced erroneously by the recording process?

You mean the little flas of light at the end in the tower? That's a reflection in the mirror system of the light house, I think.

2 years of watching the sun go down whilst in the Caribbean and I never was lucky enough to see a green flash, the ones who said they had described a mini flash of green... Our eyes capture around 10 images a second, so could it be down to the timing of our eyes capturing that image at that precise time for us to see the flash?
