Cameras are very helpful devices and are used for the sole purpose of capturing still images, may it be for leisure or security. Parts of an SLR or DSLR CameraSLR stands for Single-lens Reflex, whereas the latter stands for Digital Single-lens Reflex.
How do they Function to Produce an ImageWhat you see above is a cutaway illustration of an SLR camera. Parts of a Point-and-Shoot Digital CameraTraditional point-and-shoot cameras worked on photographic films and had static lenses.
How do they Function to Produce an ImageThe functioning of a point-and-shoot camera is nothing but a simplistic version of the SLR camera.
Advanced point-and-shoot cameras are a bit bulkier than the compact ones, but provide complex and more manipulable controls resulting in better quality pictures. From this it can be concluded that, any basic camera simply requires three things - light, a medium to receive it (pin-hole or lens), and a medium to record the image (film or sensor). Since the dawn of photography, cameras have captured and stored images on glass plates or on film. A lens is an optical component made out of glass, high quality plastic, or ceramic, which captures the light and assembles it on a point of focus at the matte screen passing through a condensing lens inside the camera. DSLR cameras are equipped with a variety of shooting modes that increase the automatic decision making of the camera.
Most digital cameras have two viewing systems - the optical viewfinder and the electronic viewfinder. As soon as I got the camera, I was immediately able to take photos without checking out the manual. You can shoot in manual, semi-automatic (where you can either adjust the aperture and the shutter speed), and fully automatic modes using the Nikon D5100. About Latest Posts Irene EnriquezIrene Enriquez loves two things: communication and technology. I carry one of these cheat sheets (Flash Cheats) around in my camera bag but now I’ve got another half dozen that I will be laminating too. Any and every camera has some fundamental parts which are very crucial for its functioning. Also, go through a brief explanation on the working principle of a camera, and different types of modern as well as traditional cameras.
These type of cameras work on a mirror and prism system which allows the photographer to preview the image before capturing it. Once this is done, the camera retracts the mirror, and the conditioned light falls on the sensor or the photographic film and the image is captured.
The viewfinder wasn't connected to the lens, but was perfectly aligned to it unlike an SLR. Recent point-and-shoot cameras do not have a separate viewfinder, and use the LCD screen to show the preview of the image to be taken.

Hence, the user simply needs to point to a subject and shoot, and the camera does the rest automatically. It is simply a black box with a pin-sized hole on one side, and a light-sensitive medium (film) on the side opposite to it. Today, digital cameras capture the images on a nifty piece of technology a€“ the image sensor. If you are looking for ease of handling, you can go for point-and-shoot cameras with fixed lenses. These cameras, thankfully, have semi-automatic and manual modes too, which put the control back in your hands for more technical and creative applications. The cameraa€™s computer determines need for flash according to the exposure metering, focusing and zoom systems. While both systems show you what the lens sees, the electronic viewfinder can tell you other things about the nature of your digital image.
Most people say that it is a versatile camera that is quite easy to use when you’re a beginner, and grows with you as you learn more about photography.
It makes me feel like I can make any subject look artistic by choosing color sketch, silhouette, or selective color.
As a beginner myself, I have to say it’s probably the perfect DSLR for beginners who eventually wish to become an advanced amateur. With this tech blog and her role as Head of Communications at Veems, she believes she has the best job in the world. Buzzle explains each of these parts in detail, and also provides a neatly labeled diagram of a camera to help you understand them better.
This is the reason why a lot of modern cameras come with an inbuilt flash that helps capture images in low light. In case of auto-focus cameras, this is done automatically using a microprocessor, a rangefinder and a miniature motor, which rotate the lens by sensing the amount of light present and the range of focus. In case of digital SLRs, the sensor transfers the captured image to a memory device, mostly a card or chip.
As they have no mirrors or prisms, and very less moving parts; they are very compact and convenient to carry. When a photographer wishes to click a shot, he presses the shutter halfway to focus (focusing is done automatically by a rangefinder usually located above the lens); once he's satisfied he presses the shutter completely and the image is captured. The hole is covered before the film is placed, and then the camera is pointed to the object to be photographed.
The image sensor is made up of millions of light sensitive photodiodes set on a grid, where each photodiode records a tiny portion of the image as a numeric value that corresponds to a specific brightness level, which is then used to create your image.
However if you are concerned about picture quality, you should invest in a digital SLR (DSLR) camera with interchangeable lenses. In PROGRAM mode, the camera sets the exposure, but the user can adjust the white balance, ISO, focusing and metering. On compact cameras the built-in flash is triggered to go off in perfect sync with the shutter, but ita€™s hard to control the timing and intensity of the flash.

But if you want to be a little more creative, you can choose from the “scenes” and “effects” settings. I only had it for a few months, but I feel like it’s going to be around for a really long time. Professional photographers manipulate light sources (spotlights and floodlights) in order to achieve better photographs of the subject. The image is transmitted to this screen and then to a pentaprism located above, which inverts the image a second time before the photographer sees it through the viewfinder. In traditional SLRs, the light sensitive medium is not the sensor but the film onto which the image is fused; the film is then processed to get a finished photograph.
Their lenses aren't static and have the ability to magnify and demagnify for telephoto and wide-angle photographs respectively.
Such cameras provide a live preview right on the LCD, which is achieved by a microprocessor, and an image sensor. The hole is uncovered once the subject is ready, and the inverted image of the subject is imposed on the film. Image sensors, whether they are CCD or CMOS, vary from camera to camera but theya€™re basically the same, and the megapixel count shouldna€™t be a priority in the decision-making process when buying a camera.
Interchangeable lenses allow you to have much more control of your images, and to be far more creative than you can be with a point-and-shoot camera. There are two semi-automatic modes: 1) Shutter Priority (Tv) is where the user sets the shutter speed and the camera determines the aperture.
The electronic viewfinder can show where the highlights are overexposing (and if youa€™ll need to compensate). Go through the images given below and try to understand the different parts of the SLR camera.
Quickly refer to the below given illustration of a disassembled point-and-shoot digital camera, and understand its different components. When the photograph is clicked, the sensor saves that particular configuration of light values into the storage device. DSLRs have pop-up flashes that can be controlled in various ways to be in-sync with the shutter or drag behind the shutter; in addition the intensity can be manipulated in accordance to the overall light of the scene.
The package came with the camera, kit lens, 8 gig memory card, charger and an Enovation bag.
For example, you can choose “pet portrait” for taking photos of your furry and active friends. 2) Aperture Priority (Av) where the user selects the aperture and the camera determines the shutter speed.
The optical viewfinder puts you directly inside the mechanical world of the camera, and tends to perhaps give you a better sense of the composition because youa€™re seeing exactly what the lens is seeing, not an electronic approximation.
