“Manual” mode, as its name implies, allows for complete manual control of Aperture and Shutter Speed. In this mode, both the aperture and shutter speed may be modified manually to any level; the camera gives you complete control over the exposure.

This setting is often required when the camera has difficulty determining the optimum exposure under extreme lighting conditions. For instance, if you are shooting a subject that has a very bright area, the camera may make an inaccurate calculation about the exposure and either overexpose or underexpose the balance of the picture as a result. In such circumstances, you may turn your camera to manual mode, check the quantity of light in darker and brighter parts, and override the camera’s exposure settings.

If you need to confirm that the shutter speed and aperture are constant throughout several exposures, manual mode is also helpful. In order to effectively construct a panorama, for instance, the shutter speed and aperture of all the images must be same.

Aside from this, some photos will be darker than others. In manual mode, once the shutter speed and aperture are adjusted to the preferred values, your photographs will all have uniform exposures.
