Many agencies provide digital cameras to their employees to document crime scenes, evidence, and other administrative functions. Unfortunately, some of these agencies do not provide adequate training for the person to whom the camera is issued, leaving them to teach themselves photography by trial and error. This course is specially designed to assist in the learning process by teaching students the correct way to prepare and use their cameras for capturing high quality digital images especially when documenting crime scenes and evidence. Students will learn how to control their aperture, shutter speed and ISO to take properly exposed photographs. In order to complete the practical exercises, students will need a DSLR or mirrorless camera capable of being operated manually.
The proper techniques required to obtain examination quality photographs that are suitable for presentation in court will be stressed.
