Digital Zoom
What is the Difference Between Digital and Optical Zoom? by Melanie Cartwright
Virtually all digital camera models that are available today offer you both digital zoom and optical zoom options. A large number of beginner photographers are not completely sure how these distinct zoom methods work, and just how they enable you to realize different effects.
Optical zoom on your camera operates in the same manner a 35mm camera’s Zoom Lens operates. Basically, it alters your camera lens’ length pulling your photographic subject closer to you. Even while doing this, the photograph’s quality is retained and not sacrificed in the slightest.
Digital zoom works in a very different way by shooting a photo, cropping it to your selected area, then enlarging the particular selected part. This leads to a decline in the photo’s quality, which can range from a slight to substantial quality loss.
So while digital zoom may well offer you a larger view of your subject, your picture will end up slightly blurry and details will be lost. If possible, it would be a sensible approach to disable your camera’s digital zoom function. This will make sure that you don’t automatically zoom in too much because the digital zoom can typically take over once the optical zoom has extended as far as it can go.
If you are aiming to get a closer shot of your subject, but still would like to preserve the photograph’s quality, there are a couple of steps you can take to accomplish that. One rather obvious approach would be to walk closer to the subject that you’re photographing. Even a foot or two will make all the difference in the world. In the event that that is not a possibility, try changing your digital camera to take pictures with the maximum file size. This will allow you to shoot the best quality picture that you will be able to crop later using an image editing application like Photoshop.
While optical zoom gives you much better quality photos, there is certainly still a purpose for digital zoom. In case your pictures are usually delivered through email or uploaded on the internet, the quality does not preferably need to be remarkable. Digital zoom will probably be more than fine for these kinds of applications. Nonetheless, if you plan on printingprinting out your beautiful photos, make sure you stay with optimal zoom and disable digital zoom.
