About a year ago I tried some IR shots with the *ist-D and a Hoya RM90 IR
filter, without great success. 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... No 2837 is dedicated to James Doohan ("Beam
me up, Scotty!")
Everything shot with the *ist-D, RM90 filter, and FA 20-35 f4 lens, gallery
slapped together in PS (sorry for the duplicate shots...)
