    The pavement has a wet look to it. Did it actually rain, or it it an effect of IR?

    Here's another image, made this summer, of the same floating dock (with some different characters) that started the thread. The time of day and direction in which it was taken are also different.

    Nikon F100, FPP InfraChrome film, Nikon 70-200 F/2.8 VRII, with a 16 orange filter and circular polarizer.

    Re: 35mm and digital infrared

    Is a D70 better for this than newer Nikons?

    I still have my D70.

    And will try it!

    Yes. Not to get into a detailed technical discussion, but the D70 has more IR sensitivity (a weaker IR blocking filter) than most other DSLRs, so you can do something useful by getting a 720nm or 760nm IR filter (these can be inexpensive, I got one on ebay) and using it unconverted. You will still need long exposures and bracketing. The above were about 1 second at f/8, and I use the self-timer or a simple IR remote to trigger the shutter. I recommend googling around for which lenses to use - some work better in the IR than others. Prime lenses with an IR focusing mark are good, but some models have undesirable reflections. Fortunately, experimenting is easy.

    I have the R72 50mm filter right here.

    I also found this page. http://nature-photography-central.co...nikon-d70.html

    I have been planning to shoot Rollei Infrared 35mm.

    Finding a lens now.

    Thank you!

    If I remember correctly.... This was shot in April, in the evening. So yes, I believe it had rained earlier.

    The D70 is pretty easy to convert and you can find them used CHEAP - I did one earlier this spring. The great advantage of doing it internally is you can view through the lens normally. I replaced the internal IR cut-off filter with a Lee polyester 87 filter in about an hour if you include the 2 re-dos I had to do in order to get the ribbon cables seated properly....
    My example from the Smoky Mountains this summer. F8, 1/500
