What your digital zoom on your camera do?

Digital zoom is a feature offered on most digital cameras. From it’s name you’d naturally expect that digital zoom does the same thing as an optical zoom lens - that is, make faraway objects appear closer and larger in the frame.

In truth though digital zoom is simply a software process that enlarges the existing image and then crops away the perimeter. You get exactly the same results as if you had done this enlarging and cropping in a photo editing program. Enlarging a digital photo can reduce the photo quality, which is why I recommend turning off digital zoom.

Digital zoom also does not affect depth of field - the zone of sharp focus like a real zoom lens.

Always take your time in pressing the shutter button.

This tip usually sound silly to people when they hear it for the first time. But one of the most common reason for improperly exposed or out of focus photos is improper shutter button technique. Most digital cameras feature automatic exposure and automatic focus. For these automatic mechanisms to work correctly, you must take a two step approach to snapping the photo.

After framing the shot, press the shutter button halfway and hold it there. In a second or two, the camera beeps or displays a light, which is your signal that the focus and exposure have been set. You can then press the shutter button the rest of the way to take the image. Try to remember that if you merely jab the shutter button down in a quick press, you don’t give the camera the brief time it needs to set the exposure and focus properly.

Sometime you may find defects in your photos.

Digital photos sometimes suffer from a defect called Noise, which makes your image appear as though someone sprinkled color sand over it. You can combat noise in two ways:

Add light, either by using your camera’s flash or switching on some other light source. Noise typically appears when the light is too dim.

If your camera offers a choice of a ISO settings, try lowering the ISO value too. This control increases your camera’s sensitivity to the light, allowing you to shoot in dim lighting. But on many cameras, a high ISO setting has the unwanted side affect of increasing noise. Of course, as you lower the ISO value, you need to add light to capture a good photo.

When taking a photo of a scene!

Try to remember as you compose your scenes, use the rule of thirds- divide the frame into vertical and horizontal thirds and position the main focal point of the shot at the spot where the dividing lines intersect, And quickly scan the frame for any potentially distracting background elements before you press the shutter button.

Try to get different angle when taking a photo.

Changing the angle from which you photograph your subject can add impact and interest to the picture. Instead of shooting a subject straight on, try investigate using unexpected angles- - try lying on the floor and getting a bug’s eye view, for example, or perch yourself on a study chair and capture the subject from above.

Think about your photo Resolution!

Most digital cameras offer a few different capture settings, each of which delivers a certain number of pixels. Before You take a picture, consider how large you may want to print the photo. Then select the capture setting that delivers enough pixels to print a good picture at that size. Your printer may produce better results when fed more pixels, how-ever experiment with different pixel setting.
Remember that you usually can get rid of excess pixels in your photo soft-ware without affecting the quality, but you almost never get good results from adding pixels, In other words, It’s better to wind up with too many pixels than too few.
