Final answer:
Marcus can mitigate his shaky hand issue in photography by using a tripod, a simple and inexpensive tool that provides stability, especially in low-light conditions where longer exposure times are required.
Step-by-step explanation:
Solving the Challenge of a Shaky Hand
Marcus, an amateur photographer struggling with a shaky hand, would find a simple and inexpensive solution to this problem in a tripod. A tripod, which is a stand with three legs, offers stability and helps keep the camera steady during the act of taking a photograph. This is particularly useful when shooting in low light conditions where longer exposure times could make hand shakiness more apparent, resulting in blurry images.
An external flash can help illuminate subjects but does not directly address camera stability. A telephoto lens, in fact, would exacerbate the issue as it magnifies the shakiness due to its long focal length. Lastly, a UV filter serves to protect the lens and reduce haze but has no stabilizing effect.
If Marcus does not wish to invest in a tripod, he can consider setting the camera on a solid surface or using other methods of stabilizing the camera to achieve a steadier shot.
