Digital Zoom Versus Optical Zoom
Many digital cameras offer both optical and digital zoom . The average camera buyer often confuse for these two, 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, draws the subject closer to you.The optical zoom keeps quality of the picture. Digital zoom works by different. It simply takes the picture also crops it then enlarges the part that is left. It causes sometimes greatly, the quality of the photo to be reduced.
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 would become lost. It is actually, if possible, best to turn off the digital zoom feature of your camera.This will prevent you automatically zooming in too close as the digital zoom is often an extension of 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 just a foot or two will do the trick. You can set your camera to take a picture at its highest file size, if this isn’t possible.These will result in a photo that could be cropped to include only your desired subject, yet allow for an image that is still clear.
Digital zoom has its place. If the only destiny of your photo is the internet, it can be used . When sent through e-mail or posted on a web gallery, photos online can be a much lower quality in the camera and still appear acceptable. However, seek a camera that has a greater optical zoom and turn off the digital zoom, if your goal is printing.Your pictures would be better in the end, although they are not as close up.
