More Fun With Filters

Today I tried shooting some infrared photos with my little Canon. I used a near opaque filter and shot with the camera in B&W mode. If you remember the visible spectrum from physics class (r.o.y.g.b.i.v.), then think of this as the light that comes right before red, more or less in the range of 850 to 1350 nanometers. The images I shot today are not sharp, mainly because I had the camera on auto-focus and it uses visible light to focus. Since infrared has a shorter wavelength you have to focus back a little. I will try again with a tripod where I can use a smaller aperture and get more depth of field.
The photo is of the center of the ASU campus, the sculpture is called �The Equinox�. Posted by Hello
