Whether you have a Digital SLRs or point and shoot , these camera parts will inevitably be found on most cameras. After getting hold of any camera, you need to know the name of the different parts before you start using it.
Single-lens reflex camera
Shutter , in photography , device through which the lens aperture of a camera is opened to admit light and thus expose the film or the electronic image sensor of a digital camera. Adjustable shutters control exposure time, or the length of time during which light is admitted. Optimum exposure time varies according to lighting conditions, movement of the subject, and other factors, and it may be either selected in advance by the photographer or, in the case of automatic cameras, set by the camera itself on a signal from a built-in exposure-metering system. The mechanical shutter can usually be set only for indicated speeds throughout its range; some electronic shutters have a continuous operating range. Modern camera shutters are of two principal types. The leaf shutter , positioned between or just behind the lens components, consists of a number of overlapping metal blades opened and closed either by spring action or electronically.
A single-lens reflex camera SLR is a camera that typically uses a mirror and prism system hence "reflex" from the mirror's reflection that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras , the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured. Bronica's later model—the Bronica EC—was the first medium format SLR camera to use an electrically operated focal-plane shutter. The Pentax Asahiflex , Japan's first single-lens reflex camera. The first was Kamera-Werke's Praktina. Canon Pellix , , the first camera to incorporate a stationary pellicle mirror.
All photographers know what a camera lens is. It lets us view and capture our environment. Some photographers find that the lens is more important than the camera. Others believe that the camera body functions and limitations are more important. You could use a pinhole and get great results.
Twin-lens reflex camera
DSLR cameras are the standard, most popular camera choice by far. They are versatile and offer professional photographs with high image quality. They can also work with an array of interchangeable lenses. Product links on ExpertPhotography are referral links. If you use one of these and buy something we make a little bit of money.
Basic Parts of DSLR Camera and Their Functions
This list is provided for those students who are enthusiasts of the manual camera. Lens - It draws the light into the camera and focuses it on the film plane. Shutter - It open and closes to control the length of time light strikes the film. There are two types of shutters: a leaf shutter, located between or just behind the lens elements, and a focal plane shutter, located in front of the film plane. Shutter Release - The button that releases or "trips" the shutter mechanism.
10 Basic Camera Parts
Whether you have a digital compact or a digital SLR, these parts will inevitably be found on most cameras. The lens is one of the most vital parts of a camera. The light enters through the lens, and this is where the photo process begins. Lenses can be either fixed permanently to the body or interchangeable. They can also vary in focal length, aperture, and other details. The viewfinder can be found on all DSLRs and some models of digital compacts. The body is the main portion of the camera, and bodies can be a number of different shapes and sizes.
A digital single-lens reflex camera digital SLR or DSLR is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder , or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. Most of the entry-level DSLRs use a pentamirror instead of the traditional pentaprism. Focusing can be manual, by twisting the focus on the lens; or automatic , activated by pressing half-way on the shutter release or a dedicated auto-focus AF button. To take an image, the mirror swings upwards in the direction of the arrow, the focal-plane shutter 3 opens, and the image is projected and captured on the image sensor 4 , after which actions, the shutter closes, the mirror returns to the degree angle, and the built-in drive mechanism re-tensions the shutter for the next exposure.
