The sensitivity of the E-1 was as low as expected, but what should be a warning to anyone considering IR photography: The step from a cut-off wavelength of 715nm to one of 780nm has a dramatic effect! The colours are totally different and the exposure time is 12x longer! | |
Thanks again to Klaus Schraeder for these shots! |
