It has never been easier to get a great picture because even the cameras in today's smartphones are incredibly powerful and easy to use. But that does not mean that we always get perfect results. You were probably in a situation where you tried to take a picture of your friend, dog or pet in front of a window or other light background just to make your subject appear as a silhouette. This is a simple problem if the camera does not know which part of the frame it should be exposed to ̵

Exposure compensation may sound complicated, but it's actually the easiest way to adjust the exposure of a camera and is a setting you'll find on just about any camera, from professional DSLRs and mirrorless cameras to your phone.
What is exposure? Compensation?
In short, exposure compensation is a simple way to adjust the exposure value (EV) of your camera's metering system. If you increase the EV value, make a picture brighter. If you reduce it, the picture gets darker. Exposure Compensation does not tell you how makes it brighter or darker, but that's the point: you do not have to worry about shutter speeds and aperture values or ISO settings.  For cameras using manual controls, note that the exposure compensation does not really affect your pictures when you are already shooting in manual mode – but it works with both shutter and aperture priority
