The drones are male bees. b. Translucent ink Without Heat Application (composition). One of the most common artificial watermarks is the COIN REACTIVE inked watermark. d. Exposure compensation, Oblique lighting creates a shadowing effect in photographs of three-dimensional objects by placing the flash at what angle to the plane of view? Although there are no specific college majors or degrees in forensic examination, scientific training is encouraged and continuing education courses are required to remain in good standing with the aforementioned boards. ACE-V Methodology Although there is an element of subjectivity .
