Final answer:
To adjust both shutter speed and aperture simultaneously, the camera should be set to manual mode. In this mode, the photographer has full control over the capture settings, potentially using a light meter to achieve the desired exposure.
Step-by-step explanation:
Understanding Camera Modes for Shutter Speed and Aperture Adjustment
If you want to adjust both the shutter speed and the aperture at the same time, you will need to set your camera to manual mode. In manual mode, you have the power to dictate both the movement capture through shutter speed, and the depth of field through aperture settings. This mode provides experienced photographers with complete creative control, often employed alongside a light meter to determine the optimal exposure settings.
Conversely, semi-manual modes such as Shutter Priority (indicated by 'S' or 'TV') and Aperture Priority (indicated by 'A' or 'AV') allow you to set either the shutter speed or the aperture, respectively, while the camera automatically adjusts the other setting to match.
Furthermore, camera scene modes such as Sports mode may also indirectly influence both settings by optimizing the camera for specific conditions, with preset shutter speed and aperture values designed to freeze action.
