If you don't want to be limited to long exposures, it is essential to convert one of your cameras to infrared, a somewhat complex procedure that consists on the removal of the Hot Mirror filter and its replacement by an infrared filter.

After several attempts, in September 2005 I manage to convert my Nikon D70 DSLR camera.

It is now dedicated to capture infrared photos.

The experience of many Nikonians has shown this -the D70- to be one of the best DSLRs for the task, if not the very best so far.

Renamed by me as D70r, the camera captures images at high speeds, making it possible to photograph people, animals, insects and sports.

After such conversion, the photographer has all the freedom for creativity as offered by a normal camera, however allowing the transformation of any scene into a dreamlike picture.

I used the Hoya R72 filter on my D70r, which still lets a part of the visible spectrum to pass, that corresponding to the red region. This allows the capture of images with different colors.

For example on a landscape photo, with a customized white balance the clear sky turns into a yellowish brown color and the vegetation to light blue.

So this opens up a wide selection of interesting post-processing alternatives and final results.

If this looks scary to do it yourself, there are companies that can do it for you.

Besides replacing the filter on top of the sensor of your DSLR, it is necessary to recalibrate the camera focus, because the infrared wavelength propagates differently -and even varies from lens to lens- making its image focus plane ahead of the plane of visible light.
