Tethered photography ofers a sophisticated strategy for direct visualization of captured images in an autopsy room, either wired or wirelessly, on larger screens (e.g., smartphones, tablets, monitors). It involves transmitting captured images from a digital camera to a computer or a mobile device, where the image iles are saved to a hard drive and displayed on the device’s screen. We present a simple technique for tethered photography suitable for an autopsy room environment based on using memory cards that can create an ad hoc Wi-Fi network to which a preferred screen device can be then connected. Wireless transfer of image iles according to their size showed delays of seconds. he maximum distance between a camera and a selected device for efective transmission of the image iles was established as 20 meters.

Real-time visualization of captured images on a larger screen instead of the small rear screens of digital cameras permits immediate control of the required quality of photographs (e.g., framing, composition, depth of ield, focus, exposure, color balance, etc.). Despite evident advantages, the lack of records in recent medicolegal literature suggests that tethered photography still has not been properly introduced into forensic pathology. his technical note aims to demonstrate a simple tethered photographic approach allowing permanent and real-time visual control of all photographs taken in an autopsy room. he technique is based on using a memory card with built-in wireless idelity (Wi-Fi) for digital cameras. Such memory cards have the capacity to establish own local wireless connection to either a mobile device or a local computer. he transfer of captured
