Lovely shots certainly a great location for Infra red.
Klaus the start of Infra red is not clearly defined, many sources quote 700nm. Human vision at the red end of the spectrum varies significantly though perhaps not quite as much as at the UV end (Young people can typically see shorter wavelengths) In any event R72 is very much the standard for infra red photography. |
