Thank you very much, Jim!

The colors are definitely “unusual” but I like them! And that’s from using IR filters on a full spectrum camera, huh?




Joshua, yes, the so-called IR-Chrome filter gives these results nominally in-camera. You can get similar results with a 590nm filter and flipping blue and red channels in Photoshop like these:

You can also tone down the saturation or shift the color hues. Less permissive filters work best as BW. Many of the most famous BW landscape photos from Ansel Adams used either a dark red or infrared filter to yield dark skies contrasting vs white clouds and to differentiate foliage from dirt, rocks, or tree trunks.

I am no Adam’s, but this is an example of a more contrast BW:

IR can also reveal unexpected patterns in things like rocks. Imagine a dull looking stone that suddenly looks like complex marble. At least for landscapes, IR is also fun/useful to cover bad shooting times for visible light. High noon? Perfect for IR, since contrast improves when light intensity increases. Conversions to either full spectrum or an internal filter with a particular wavelength cutoff run about $250, so they can be an interesting alternative to selling an old camera body.

Probably more than you wanted to know…

Best,
Jim
