Many digital cameras supply both digital and optical zoom.  These two frequently 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 merely takes the picture and crops it then enlarges the component that is left.  It causes the high quality of the photo to be reduced, occasionally greatly.

What this means in terms of output is you could have a larger view of an object with the digital zoom, but chances are your image will turn into unfocused.  Details will grow to be lost.  It’s really greatest to turn off the digital zoom feature of your digital camera if achievable.  This will stop you automatically zooming in too close as the digital zoom is generally an extension of the optical.

You will discover 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 whenever you take the picture.  Frequently only a foot or two will do the trick.  If this isn’t possible, it is possible to set your camera to take a picture at its highest file size.  This will result in a photo that will be cropped to consist of only your desired subject, yet allow for an image that’s still clear.

Digital zoom has its place.  It may be used if the only destiny of your photo is the web.  Photos on-line can be a significantly lower quality within the camera and still appear acceptable when sent by way of e-mail or posted on a web gallery.  If your objective is printing, having said that, seek a digital camera that has a greater optical zoom and turn off the digital zoom.  Your pictures will be far better in the end, even if they are not as close up.
