Digital Zoom Versus Optical Zoom

Many digital cameras offer both digital and optical zoom. These two often confuse the average camera buyer, until you know what you’re looking at.

Optical zoom works much like the zoom lens on a 35 mm film camera. It changes the length of your camera’s lens and draws the subject closer to you. The optical zoom keeps the quality of the picture. Digital zoom works differently. It simply takes the picture and crops it then enlarges the part that is left. It causes the quality of the photo to be reduced, sometimes greatly.

What this means in terms of output is you may have a larger view of an object with the digital zoom, but chances are your image will become unfocused. Details will become lost. It is actually best to turn off the digital zoom feature of your camera if possible. This will prevent you automatically zooming in too close as the digital zoom is often an extension of the optical.

There are a couple of things you can do if you want a closer view of a subject but want the quality of your picture to still be good. Try moving in closer when you take the picture. Often only a foot or two will do the trick. If this isn’t possible, you can set your camera to take a picture at its highest file size. This will result in a photo that can be cropped to include only your desired subject, yet allow for an image that is still clear.

Digital zoom has its place. It can be used if the only destiny of your photo is the internet. Photos online can be a much lower quality in the camera and still appear acceptable when sent through e-mail or posted on a web gallery. If your goal is printing, however, seek a camera that has a greater optical zoom and turn off the digital zoom. Your pictures will be better in the end, even if they are not as close up.

How Many Mega-Pixels Do I Need?

One of the confusing things in choosing a digital camera is deciding how many mega-pixels you should look for. The answer depends on what you plan on doing with the finished pictures.

First, you need to understand what a pixel is. In terms of digital prints, a pixel simply means a dot of color that makes up the image. A mega-pixel is equal to one million pixels. The more mega-pixels a camera has, the greater the amount of information it records.

The easiest way to decide what to look for is to know what size prints you are likely to print from your camera. A one mega-pixel camera is fine for those who don’t plan on printing photos but rather just post them on the internet. A small print, say 4 x 6, will print acceptably from this camera.

A 2 mega-pixel camera will enable you to produce good quality 5 x 7 prints and fair quality 8 x 10 prints. When you reach 4 mega-pixels you can print out excellent quality 8 x 10 prints and acceptable 11 x 17 prints and a 5 mega pixel camera will allow you to print out high quality 11 x 17 prints.

Most families find a camera in the 3.2 Mega-pixel range to be the best choice. The quality of both 5 x & and 8 X 10 prints is very good yet the files on your computer are not so large you need worry about not having enough space.

Any camera over 5 mega-pixels is unnecessary for all but professionals in photography; even then, only those who have need for poster-size prints find that many mega-pixels worth the money. Most freelance photographers find 4 or 5 mega-pixels to be sufficient for excellent-quality prints.

The choice is yours. Look to what you plan on doing with your photos and then decide. In most cases spending the money for increased optical zoom and lower mega-pixels is the best choice.

White Balance Setting on the Digital Camera?

Have you ever taken a picture of a beautiful winter scene and been disappointed to discover the crisp, white snow came out with a bluish tint?

This is the kind of situation your digital camera’s white balance is meant to prevent.

The white balance is a sensor that analyzes the lighting conditions and colors of a scene and adjusts so the white in the picture appears white. This helps insure the other colors appear as natural as possible. This is one advantage digital photography has over tradition film.

With film, you buy with a certain lighting condition in mind. If that changes, you need to either change your film or hope you can fix any errors in post-production.

Most digital cameras allow you to use either automatic white balance or choose between several preset conditions such as full sun, cloudy day and so forth. Automatic white balance will work in most conditions.

There may be times, however when you want to “warm” up a picture to enhance the color, such as for portraits or sunsets. The best way to do this is set your camera’s white balance to “cloudy”. This will deepen the colors and add a glowing quality to portraits. It will take a beautiful sunset and enhance it to the point of incredible.

Practice taking the same photo with different white balance settings to get a feel for the changes each setting evokes. Keep notes until you have a good idea of what each setting does. In time, you will come to automatically sense which setting is best for your particular situation.

White balance is a small setting that can make big changes in your finished photos. Make it your friend and you will no longer have to worry about faded sunsets or blue snow.
