DSLR a Digital Single Lens Reflex camera (also called a digital SLR or DSLR) is a digital camera combining the optics and the mechanisms of a single lens reflex camera with a digital imaging sensor as opposed to scheme is the primary difference between a DSLR and other digital camera
How to set up a camera for the first time.
- Changing Battery Unless your camera takes AA batteries the first thing you have to do after opening the box charge the battery.in some cases there will be a battery charger supplied which needs to have the battery inserted and then be connected to the main but some batteries are charged inside the camera via a USB connection.
- Format the card once the camera battery is charged and inserted pop the memory card in its port then turn the camera on press the menu button and search for the Format option. When you format a card it deletes all existing images and prepares the card for the use by the camera. If you have used the card before make sure that you have downloaded and saved any images that you to keep before formatting
- Image Quality and size you want to get the best image you can from your new camera so set the image size to large to get the full benefit of all those pixels. Then set the image quality to the best available option its often called highest JPEG fine JPEG or extra Fine JPEG. If your camera also offer the ability to shoot raw files you might want to shoot these at the same time as JPEGs because they contain the most image data. However the downside of raw files is that you have to process them and convert them to a universal file format such as TIFF or JPEG before you can share them with friends and family.
- White Balance-Auto our eyes and brains are really at compensating for the different colours of light that we encounter so that we see white objects as white.n some situations, however, it may not be able to completely remove a colourcast and one of the settings that is designed for use in those specific lighting conditions, such as fluorescent or tungsten, may be a better choice.
- Focus-Auto-AF or Singe-AF In Singe-AF mode your camera will focus on the subject under the active AF point when you press the shutter release button half-way.Once it has focused, the lens it will lock the focus at that point for as long as you hold the button down. This is a good option for many situations, but if the subject moves, the focus will not be adjusted.Many cameras have an Auto-AF option in which the camera automatically detects whether the subject is moving or not.If the subject is stationary, Single-AF is used, but if it moves the camera activates the Continuous-AF system so that the focus is adjusted as necessary.If your camera has an Auto-AF mode, use it, otherwise use Single-AF.
- AF Point selection-Auto In Singe-AF mode your camera will focus on the subject under the active AF point when you press the shutter release button half-way.Once it has focused, the lens it will lock the focus at that point for as long as you hold the button down. This is a good option for many situations, but if the subject moves, the focus will not be adjusted.Many cameras have an Auto-AF option in which the camera automatically detects whether the subject is moving or not.If the subject is stationary, Single-AF is used, but if it moves the camera activates the Continuous-AF system so that the focus is adjusted as necessary.If your camera has an Auto-AF mode, use it, otherwise use Single-AF.Most cameras have a setting that tells the camera to and it’s a good choice when you’re first starting out with your camera.The camera will tend to assume that your subject is the nearest object and near the centre of the frame, so if you have an off centre subject and other objects between it and the camera, keep an eye on what the camera is choosing to focus on.If necessary, switch to single-point AF (or similar) which allows you to set the AF point using the navigation buttons.
Drive Mode-Single When your camera is in Single-shot mode it will only take one shot every time you press the shutter release button – even if you keep your finger held down.In Continuous mode it will continue taking photographs until you release the button, or the buffer or card fills – whichever happens first.This can be useful with moving subjects, but in most instances you just want to take one photograph at a time.
Wide-angle lens:
In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it. Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away.
Telephoto Lens:
A lens with a longer focal length than standard, giving a narrow field of view and a magnified image.
In photography a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length.This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.
What is ‘depth of field’?
A camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp.This zone is known as the depth of field. It’s not a fixed distance, it changes in size and can be described as either ‘shallow’ (where only a narrow zone appears sharp) or deep (where more of the picture appears sharp).
Why do I need to know about it?
Because depth of field has an impact on both the aesthetic and technical quality of a picture. Sometimes you’ll want to use an extensive depth of field in order to keep everything sharp.
A classic example is when you’re photographing a landscape, where generally the most desirable outcome is to capture detail from the foreground to the horizon.
Other times, a shallow depth of field will be preferable. It enables you to blur background and foreground details, causing distractions to melt away and allowing you to direct viewers to the focal point in a picture.

Manual mode:
The camera does this for you in the automatic and semi-automatic exposure modes, tweaking the aperture, shutter speed or both in order to maintain a consistent exposure. However, the fact that the aperture and shutter speed settings stay locked in with Manual mode is its chief advantage.

Fast Shutter Speed:
Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely, as seen in the above photo of the dolphin.
