Digital Versus Optical Zoom
Most cameras offer both digital and optical zoom. These two often confuse the typical camera buyer unless you know what you are considering.
Optical zoom works similar to the zoom lens on the 35 mm film camera.
It changes the length of your respective camera’s lens and draws this issue closer to you. The optical zoom keeps the grade of the picture.
Digital zoom works differently. It simply takes the photo and crops it before enlarging the part which is left. It causes the standard of the photo to be reduced, sometimes greatly.
What this implies in terms of output is that you simply may have a larger look at an object using the digital zoom, but odds are your image can be unfocused.
Details can be lost. It is really best to switch off the digital zoom feature of your respective camera when possible.
This prevents you automatically zooming in too close since the digital zoom is usually an extension from the optical.
There are a handful of things you are able to do if you prefer a closer look at a subject but want the standard of your picture to be good. Try relocating closer whenever you take the photo.
Often simply a foot or two is going to do the trick.
If this is not possible, you are able to set your digital camera to take a photo at its highest file size. This can lead to a photo which can be cropped to incorporate only your desired subject, yet enable an image which is still clear.
Digital zoom has its own place. It can be utilized if the only destiny of the photo will be the internet.
Photos online could be a much lower quality within the camera yet still appear acceptable when sent through e-mail or posted with a web gallery.
If your main goal is printing, however, seek a camera which has a greater optical zoom and switch off the digital zoom. Your pictures will be better inside the end, even when they are not as close up.
