READY FOR GRADING

A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the image, just as with film but the image pickup device is electronic rather than chemical. Digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Other capabilities of most modern digital cameras consists of recording videos with sound, cropping, and stitching photos all within camera.

Digital single-lens reflex cameras (DSLR)


Digital single-lens reflex cameras (DSLR) is a camera with a digital sensor that utilizes a reflex mirror to split or direct light into the viewfinder to produce an image. The reflex mirror finds the image by blocking light to the cameras sensor and then reflecting it into the camera's pentaprism which allows it to be seen through the viewfinder. When the shutter release is fully pressed the reflex mirror pulls out horizontally below the pentaprism briefly darkening the viewfinder and then opening up the sensor for exposure which creates the photo. '''The digital image is produced by the sensor which is an array of photoreceptors on a microchip capable of recording light values. Many modern DSLRs offer the ability for "live view" or the framing of the subject emitted from the sensor onto a digital screen.'''

The sensor also known as a full-frame sensor is much larger than the other types, typically 18mm to 36mm on the diagonal (crop factor 2, 1.6, or 1). The larger sensor permits more light to be received by each pixel; this, combined with the relatively large lenses provides superior low-light performance. For the same field of view and the same aperture, a larger sensor gives shallower focus. DSLRs can equip interchangeable lenses for versatility by removing it from the lens mount of the camera, typically a silver ring on the front side of DSLRs. '''These lenses work in tandem with the mechanics of the DSLR to adjust aperture and focus. Autofocus is accomplished using sensors in the mirror box and on most modern lenses can be activated from the lens itself which will trigger upon shutter release.'''

List of digital camera manufacturers

There are many manufacturers that lead in the production of digital cameras (commonly DSLRs). Each brand embodies different mission statements that differ them from each other outside of the physical technology that they produce. While majority manufacturer share modern features amongst their production of cameras, some specialize in specific details either physically on camera or within the system and image quality.
