the first four (color) pictures were taken using the Hoya RM72 infrared filter in "nightshot" mode, with an additional Hoya ND8 filter for exposure. Black and white versions of all photos are given below each color photo. The last two pictures are taken using a Tiffen Orange #21 filter, the first in nightshot and the second in regular exposure (i.e, the lower right pictures are visible, not infrared, light) . It is clear that infrared light largely dominates the exposure of the picture when "nightshot" is enabled, however the interesting factor is the ability to add back a small amount of visible light to give much greater differentiation of colors. I'm definitely going to see what can be accomplished playing with this.
I'm using a custom white balance in all of the photos, using the Sony Camera RAW editor supplied as a downloadable plug-in to Adobe Photoshop CS.
