INTRODUCTION

DSLR

A single lens reflex (SLR) camera is a camera with one lens that uses a mirror and prism to reflect the photographic image into the camera’s viewfinder. SLR cameras that store these images on digital cards, instead of imprinting images on film, are known as digital SLRs or DSLRs. Images from these digital cameras can be printed by the user using a personal printer, or by professional photographic developers. Digital images can also be manipulated using various software applications prior to printing.

DSLRs are often preferred by professional still photographers because they allow an accurate preview of framing close to the moment of exposure, and because DSLRs allow the user to choose from a variety of interchangeable lenses. Most DSLRs also have a function that allows accurate preview of depth of field.

Many professionals also prefer DSLRs for their larger sensors compared to most compact digitals. DSLRs have sensors which are generally closer in size to the traditional film formats that many current professionals started out using. These large sensors allow for similar depths of field and picture angle to fill formats, as well as their comparatively high signal to noise ratio.

POINT AND SHOOT DIGITAL CAMERA

A point-and-shoot camera, also called a compact camera, is a still camera designed primarily for simple operation. Most use focus free lenses or auto focus for focusing, automatic systems for setting the exposure options, and have flash units built in.

Point-and-shoots are by far the best selling type of separate camera, as distinct from camera phones. They are popular with people who don’t consider themselves photographers but want an easy to use camera for vacations, parties, reunions and other events.
