infrared false colour taken with sony 717 two ND filters and ir-filter 720nm , in nightshot mode .
I was always thinking about colours . Are they real ? Do colours really exist ? The quick answer is NO, colours do not really exist . Colours are a way our brain uses to define different lenghts of light waves. Some are visible , some invisible like infrared IR and ultraviolet UV. The fact we don't "see" these kinds of light doesn't mean they don' t exist , at least as length, and so we can capture then with moddified cameras . But we have to transform these to visible colours, false colours.
Ok , no more Physics , i start to get confused !
Thanks for looking !
