- Digital infrared photography can be used by crime scene investigators as a nondestructive test for examining gunshot residue (GSR) on dark and multi-colored fabrics found at the crime scene. When a firearm is discharged a plume of gunshot residue exits the barrel and creates a visible powder pattern on light-colored clothing at specific muzzle ...

- correction was not necessary for photographing the GSR patterns in this experiment. The f 3.5 aperture setting provided enough depth of field without manually correcting the focus. Another advantage of digital infrared photography over traditional infrared photography is that the digital image does not require any chemical processing of film ...

- standard for comparing the visible GSR pattern to the digital infrared GSR pattern images. Digital infrared images were photographed with a 35 mm Nikon D-70 camera with an 18-70 mm f 3.5 – 4.5 G ED-IF AF – S DX Nikkor lens and a 67 mm #87 infrared Tiffen filter. Experimental flash and camera settings were used to determine the most

- IR photography turns reality into dream-like scenes. Named after infrared trailblazer Robert Wood, the most common result of infrared photography is called the “Wood Effect.”. With the Wood Effect, infrared images of scenes reflect light so that foliage looks white and skies take on unusual colors, whether you shoot in black and white or ...

- A digital infrared conversion involves removing the infrared cut filter covering the camera filter and replacing it with an infrared filter. The infrared filter blocks visible light but allows infrared light to reach the sensor to create the infrared image. The replacement infrared filters come in different strengths depending on the wavelength ...
