“…A recent study by Barrera et at., conducted test firings at 20 cm (~7.87 inch) and concluded that outer gunpowder soot area can be visualized by the combination of an orange-colored filter and 440-nm illumination while the inner gunpowder soot area can be visualized by infrared photography. 16 We conducted an application on dark, patterned and bloody samples from different shooting distances ranging from contact to 36 inches, and our measurements were based on inner gunpowder soot area. MGT and SRT were respectively applied to the control white fabrics on which blood was sprayed.…”

“…The authors do not suggest IR photography of all gunshot wounds. Infrared photography can be used to highlight gunshot residues on dark clothing, on dark skin, and on skin where decomposition may limit evaluation [13]. The use of IR photography was useful to highlight the comet-tailing observed in case 2; however, it was not necessary to use IR photography to demonstrate comet tailing in the other cases.…”

Many handgun projectiles are either completely composed of lead or contain a lead core covered by a partial or full "jacket" of metal.Bullets have jackets in part to reduce fouling of the weapon's barrel during discharge. Metal bullet coverings range from full metal jackets to "gilded." Jacketed bullets contain a relatively thick metal (often copper, occasionally other metals) covering, while many .22 caliber bullets are "washed" or "gilded" with a copper-like coating that seems to have been sprayed onto the bullet surface. "Electroplated"or "plated" projectiles may be considered "in-between" classic jacketed and "gilded" bullets. Plated bullets have a metal covering which is not as thick as the metal of typical jacketed bullets, but it is thicker than the very thin "wash" which exists on gilded bullets. Because a plated bullet's coating is thinner than normal jacket material, the electroplating material can, in some situations, break apart or fracture while being fired [1,2]. Presented here are three cases of homicidal gunshot wounds, with each demonstrating "comet-tailing," an unusual feature resulting from fractured plated bullets.

“…Barrera et al compared the use of an alternative light source with infrared photography to visualise GSR patterns [ 105 ]. Twenty-six dark materials were shot at a distance of 20 cm with a 0.44 revolver.…”
