Photography Digital Cameras

Cameras can be divided into several major types. Although most cameras operate in roughly the same way, there are a few notable differences. It helps to know what type of camera you are using, and what its strengths and weaknesses are.

Common Components

Firstly, let’s look at what cameras have in common. Except for some specialist types of camera, all cameras have the following basic components:

• Body: A light-tight compartment to house the recording medium (film or CCD).
• Lens: A transparent element to focus light rays onto the recording medium.
• Aperture: A method of controlling how much light reaches the recording medium.
• Shutter: A method of controlling how long the recording medium is exposed to the incoming light.
• Viewfinder: A way to see the image that is to be captured.
• Transport: In film cameras, a method of moving the film and holding it in the correct position.

Types of Camera

• SLR (Single Lens Reflex): The viewfinder sees the same image as the main lens, i.e. what you see is what you get. SLRs also allow you to change lenses for different purposes. This is a hugely popular type of camera, pretty much the standard for enthusiasts and professionals.
• Viewfinder (or range finder): In this type of camera the viewfinder is separate to the lens. This is common in cheap cameras, although some professional cameras also use this configuration. The main problem with a separate viewfinder is that the image you see may not be quite the same as the image that gets recorded. This limitation is overcome in professional cameras by using viewfinders that compensate for the different positions. Viewfinder cameras do have some advantages; for example, lower noise and higher light levels to the viewfinder.
• Twin reflex: The camera has two lenses - one for the photograph and one for the viewfinder. This type of camera has certain advantages in some professional situations.
• View: A flexible bellows joins two standards - one with the lens and the other with the viewfinder or film. This allows for unusual types of composition; for example, distorting the shape of the image by skewing the film plane.
• Pinhole: A very simple camera without a lens.

How To Master Digital Photography Basics

Cameras and Photography

With the advent of digital cameras, the cost of photography has plummeted considerably, with the result that there has been a surge of interest in the field.

Mastering the basics of digital photography, first and foremost involves knowing all about pixels and resolutions. Let us discuss a few basics of digital photography. The Optical Zoom of a camera is worth tinkering with. The “Telephoto” mode makes your subject appear larger while the “Wide Angle” mode is all about cramming a lot of a scene into your picture and hence the elements of the picture appear smaller.

For instance, instead of relying on the instruction manual, see for yourself that the Portrait Mode actually sharpens your subject and de-focuses the background. For those who are not yet comfortable with the exposure, focus and flash parameters can take the help of the Auto Mode in the awkward initial stages.

Lighting

There is no such thing as a photography gene. Good photographers weave magic with their cameras, but this magic is all about getting the lighting and flash issues straightened in their photographs.

Using the Flash

The flash is quite a lure for the novice photographer but results are not always satisfactory.

Shutter Speed

The shutter speed is one area that many newcomers to digital photography is quite oblivious to. The rule of thumb: fast shutter speeds “freeze” the action, while slow values will result in a blur. Slow shutter speed also let more light enter into the camera, so this is an option worth considering when you need to shoot in low light conditions.

The basics of digital photography are not hard to master.
