Infrared Lighting Gallery


Below are a few examples of the utility of IR illumination in the field of wildlife biology. All of the images here were recorded on Sony digital Night-Shot cameras (model TRV-9) with LED IR arrays. These camcorders generally give the images a green tint when used in this IR sensitive mode. Many commercial camcorders are now on the market with this or similar features that allow the camera to use IR light. These camcorders give the user a compact package for field use and yield high quality images for later analysis.

In many respects these examples do not do true justice to the original recordings. We have had to downsize the images and reduce the frame rates to create computer files with reasonable file sizes for use on a website.

A ringtail (Bassariscus astutus) emerging from an abandoned mine near Tucson, Arizona. The ringtail clearly spotted the recording equipment sitting beside the mine entrance. We don't know if it saw, heard, or smelled the gear. But after a quick look it went on about its business. For a short video clip, select the links below...

Below: A maternity colony of lesser long-nosed bats (Leptonycteris curasoae) in a mine in southern Arizona. The image at the left is wide angle, at right is the image of the indicated area with the camera zoomed in. The images were obtained with a camcorder and a single IRLight6 from the entrance of the mine without entering the roost.
