Your in good company.... and I like your test. For myself I can sometimes get better quality using digital zoom by lowering rhe resolution on the camera I am sort of guessing that the camera shake or vibration is not as much of a problem?

One of the numerous reasons Irecently bought a Casio EX-Z750 as a replacement for my Casio QV-5700 (which I have kept) was its 7Mpixels, compared with the QV-5700's 5Mpix. This means I can zoom digitally on the computerOR in the camera, and maintain quality rather better. I lost a whole stop of lens aperture, though (f/2.8 instead of f/2), and that's why I kept the QV-5700.
As a former OM-10 SLR owner with 35-80 and 80-210mm lenses, I've always felt the need for a longer zoom, but I also want a compact digicam. I find 5Mpix is adequate most of the time, and I do really big prints with reasonable quality, so I have my new 7Mpix camera set most of the time to 5Mpix. This makes all post-processing and storage on my antique 400MHz Pentium II a lot quicker, because the files are about 1600KB instead of 2000KB. I have the digital zoom on the Z750 switched off, usually, but it's there when I want it. Times when I use it are when memory card space & battery power are at a premium, e.g., when in remote locations, or when I forget to take the charger on holiday. So I still tell people digital zoom is useless, but don't fully believe that any more. Happy shooting! |

New conclusion: The best resamples for this subject matter were done with the Mitchell and the Bell methods, and both came out pretty darned close to the image that my camera interpolated when I set the digital zoom to 13x. It was basically a draw, although the camera-interpolated image may have been a tiny bit better in some spots. Certainly it was no worse. I guess I'll continue to try out the digital zoom in different situations. So far it doesn't seem to have any noticeable downside except for the fact that I'm going to have to use a tripod more often. |
