Digital zoom enlarges the pixels in the camera, in the same way as in Photoshop you can enlarge a photo, so while size increases, resolution goes down. Optical zoom works by increasing the magnification of the optics, thus the resolution stays the same, but, say, the beauty, takes up more of the frame, much like when you creep up close (the perspectives differ between close-ups and zoom pictures, of course). So there is never any need for using digital zoom. If you want to enlarge part of a scenery more than the optical zoom can handle you do it afterwards in Photoshop, or similar program. Actually, there are three things one should learn using Photoshop, or similar program. That's all - the rest is for creative photographic editing! 1. Learn to crop a photo, cutting away parts of the photo that distract. 2. Learn to re-size a photo, so that its size and resolution is adapted to the medium your going to use. A somewhat dizzy photo, that you want to keep as a memory, or other reason, never gains anything to be saved in full size, often the reverse. A crisp photo, on the other hand, should be kept in as big format as possible - who knows, one day it might be published, and printed! A slightly blurred photo looks better if decreased in size a bit, due to the way our eyes work, so that's why pictures should be taken in as big size as possible, till you checked them in your computer. 3. Learn to use Levels - a much better tool than Brightness and Contrast, which only occasionally can be helpful! Now you're all experts and can work as photoeditors at any newspaper!
