Manual mode lets you choose the aperture, shutter speed, and ISO independently, without any automatic adjustments from the camera. Manual mode gives you the most creative freedom and control over your exposure, but it also requires more skill and experience. You can use manual mode when you want to achieve a specific effect, when you are working with consistent or challenging lighting conditions, or when you are using external light sources. For example, you can use manual mode to create long exposures, HDR images, or flash photography. Manual mode is ideal for advanced photography, such as night, studio, or artistic.
