What you need to know about the different modes your digital camera offers

There are several things that you need to know about the different modes and features that your digital camera offers.Here are some of the most common modes and different settings offered by the most typical digital cameras.Also included are definitions of common terms that you need to know so that you can utilize the modes offered by your digital camera to their very best advantage.

  1. Auto focus and fixed focus.:Digital cameras come with two different kinds of focus: auto focus and fixed focus.The lower grade digital cameras generally come with fixed focus.Older digital cameras probably also have fixed focus.This means that the focus lenses are fixed to a depth of 2-3 feet and onward.If your camera has a fixed focus, then it will not automatically focus on the subject, like an auto focus will.However, the shutter speed on a fixed focus will be faster.If you're only going to be using your camera for really quick photos that are close at hand, then a fixed focus camera will probably be okay. Auto focus cameras are standard for better digital cameras.With an auto focus camera, you point the camera at the subject.You then push the button halfway down so that the camera will focus itself on the subject.Then you take the picture.Auto focus cameras are slower than cameras with fixed focus, but they work much better for pictures of anything far away, or anything that you want a sharp, clear photo of.
  2. All about compression:If you are going to be taking digital photos and then storing those photos, then you need to know about photo compression.Every time you take a picture, your camera compresses the image in order to store it.This means that the camera is making the file size of the image smaller.The compression size of your camera depends on each camera.The less compression that occurs, the better the image will be ultimately.Digital cameras that use memory cards rather than floppies will have better images, because memory cards can store much more data.
  3. Know your sensors: C.C.D. and C.M.O.S.If you go to your local electronics store, you probably won't be hearing these words tossed around.But you need to know what they are.The way that a digital camera works is by capturing an image by using a sensor.Higher quality digital cameras will use a C.C.D. sensor, which stands for charge-coupled-device.The quality and size of the sensor will be expressed through its pixel size.Cheaper digital cameras will use C.M.O.S. sensors (complementary metal oxide semiconductor), and will have a much worse image quality.So make sure that when you shop for your digital camera, you purchase one with a C.C.D. sensor.The exception is digital SLR cameras.
  4. Flash:Different cameras have different ranges of flash.The lowest quality digital cameras might not even have a flash at all.If you want to be able to control the flash on your camera in order to get a better image quality, then you should set your own flash timing.
    You also have the option of using an external flash to improve the flash quality on your digital camera.The majority of digital cameras don't have very powerful flashes, unless you get a particularly high quality model.
  5. Understand your zoom:There are two different kinds of zoom that come in different digital cameras: optical zoom and digital zoom.Digital zooms are not worth your money; all that digital zooms do is enlarge the center of the image.However, an optical zoom functions like a binocular or telescope.Work with your zoom buttons to get exactly what you want in your picture.
