Great images. Really enjoyed the sixth one. Been a long time since I've shot infared and know there are two rolls in the freezer.

This weekend I tried it again just hanging out around the house, and was surprised to get much better images. So yesterday I did some digital IR work in the area where I shoot bugs, and here's a little gallery with a few shots around the house plus a few from the field. It was a bit inconvenient having to remove the filter to compose the image (the RM90 is black), but if the IR filter is used with IR film it's the same drill. At ISO 1600 exposure times were in the 1 to 8 second range. The exercise made me appreciate how you really can't guess how much IR light is out there. A change in the angle between the sun and the camera could result in a full stop or two exposure changes (makes me wonder if IR light is highly directional in how it reflects off things.) One nice thing - the *ist-D AF not only worked well through the IR filter, but accurately focused and compensated for the IR focusing differences. Sensor flare was another un-predictable phenomena, showing up mostly in low light / long exposure situations. The long exposures really chewed down the batteries. The images come off the camera monochrome magenta (in auto color balance.) These have been desaturated (to varying degrees) with new white and black points set on the rather compressed histogram. Anyhow - nothing notable in these shots other than a glimpse at the potential of IR work with the *ist-D. Though I am becoming fond of lens flare as a creative element...

Everything shot with the *ist-D, RM90 filter, and FA 20-35 f4 lens, gallery slapped together in PS (sorry for the duplicate shots...) http://www.markcassino.com/temp/peso/iw/ - MCC - - - - - - - - - - - - - - - - - - - - Mark Cassino Photography Kalamazoo, MI www.markcassino.com - - - - - - - - - - - - - - - - - - - - -- No virus found in this incoming message.
