Basics of the Digital camera

 

 

 

When you are experiencing anything for the first time, as with most things in life, you are often unclear of how to proceed. When purchasing your first digital camera, the same may be said. You’ll surely be bombarded with data, figures, and more language than you can handle. We’ll try to explain some of the lingo and teach you what to look for when buying a digital camera in this article. Some of the features may not be important to you unless you require your camera to accomplish specific jobs, but it’s always helpful to know what you’re getting so you can spot a good price when you see one.

Optical Zoom vs. Digital Zoom

When shopping for a camera, you’ll almost certainly want one with a zoom option for those distant images. For some first-time purchasers, this is a difficult region to navigate. For digital cameras, there are two types of zoom available. There are two types of zoom: digital and optical. The only one that matters is optical zoom, which is a true zoom capability that uses the camera’s optics to bring items closer to you. Digital Zoom is similar to using the zoom feature in an image editing program. It magnifies a portion of the image to make it appear closer to you.

Anything you can do with digital zoom, you can accomplish with a photo editing program, so don’t spend a lot of money on a camera that solely has digital zoom. You may also see the term “total zoom” marketed, which means that the figure mentioned above is the optical zoom magnification multiplied by the digital zoom magnification. For the camera’s genuine value, try to determine the magnification level of the optical zoom alone.

Megapixels

A camera’s resolution is measured and advertised in megapixels. The amount of pixels that the camera must use to take an image is the concept underlying this statistic. In this situation, the larger the number, the higher the quality of the photo you can shoot. If you buy a camera with a resolution of 4 Megapixels, for example, the images you take with that camera will have a resolution of 4 million pixels. It’s self-evident that a camera with a 2 megapixel resolution will not produce an image as clear or detailed as one with a 4 megapixel resolution.

If you frequently print your photos on your computer or have them printed elsewhere, the megapixel rating of your camera is critical. Higher megapixels on your camera enables you to produce larger prints without sacrificing quality. When you try to print a photo in a size larger than your camera was meant for, the image loses a lot of quality.

The last point to remember about megapixels is that the higher the resolution you use, the more space your memory card will take up. A photograph shot with a 4 megapixel camera will use double the amount of memory card space as a photograph shot with a 2 megapixel camera. If you want nice images, make sure your camera has adequate capacity to back them up, or have replacement media cards to plug in once your space is depleted.

Aperture

We’re probably going a little deeper here than some of you want to go, but stay with us because aperture size has a major impact on your photos. When you snap a photo, the aperture size determines how much light is let into the camera. Consider the aperture to be your eye’s iris. You might assume that having more light isn’t a significant deal, but having more light allows you to shoot better images in a range of lighting conditions, such as cloudy days.

With a large enough aperture, you’ll be less likely to use the flash; personally, I don’t like to use the flash because the artificial flash of light doesn’t always do the photo credit. Red eye is also a common side effect.

Storage Media

A slot for a variety of media cards is included with digital cameras. Check what kind of storage media your camera requires when you buy it. Smart Media, Compact Flash, and xD photo cards are among the most common types. You should be able to safely purchase the correct type if you know what type you are. If you’re unsure, always ask at your local store. They should be able to lead you in the appropriate route if you provide them with your vehicle’s make and model.

The amount of the media card you select is determined by your budget; however, buy as much as you can. More memory means you won’t have to change media cards as often, and you’ll be able to snap high-quality photos all of the time. When you start using your camera on a regular basis, you’ll quickly realize the advantages of having plenty of storage space.

The advantage of camera media is that, like film, if you run out, you can simply insert another one if you have one on hand. It can be inconvenient to download your photos to your computer, but it is far less inconvenient than having to delete a photo because your media card is full.

Speed of the Shutter

Using a variety of shutter speeds, you may create amazing effects in your photos. When it comes to shutter speeds, the broadest range possible is what you should search for when purchasing a decent digital camera. This gives you the best chance of getting the image to look the way you want it to. When used in conjunction with a pro-active aperture, shutter speed may bring images to life or freeze them in time.

When you wish to capture moving things in their precise state as if they were motionless, this technique is ideal. Slowing down the shutter speed offers the CCD (charge coupled device – the digital equivalent of film) greater exposure. The result is that the image appears to be running. Moving items have a small blurring effect. You might think this is a terrible thing, but if you’re photographing moving water, slowing down the shutter speed will soften the image and make it more pleasant to the eye, similar to how a cascade seems in real life.

With a camera that has a wide variety of shutter speeds, you can push digital photography to its limits. With a very slow shutter speed, you can get a long exposure of light to the CCD, similar to the famous traffic scenes when the headlights melt into one another in a continuous stream.
