What are the main differences between an SLR camera and a point-and-shoot camera, and how do these differences impact the quality of photographs taken with each type of camera?

The main differences between an SLR camera and a point-and-shoot camera lie in their lens interchangeability, manual control options, and image sensor size. SLR cameras offer more control over settings and the ability to change lenses, resulting in higher quality and more customizable photographs. Point-and-shoot cameras are more compact and easier to use but may produce lower quality images due to their fixed lenses and limited manual controls.
