You'll probably end up with a better result if you crop and blow up, because a lot of software has better resizing techniques than what would be in your camera.
It all has to do with interpolation. Which ever (camera or software) has the better technique will win. Software usually has the better technique in most cases.

Depends i suppose on the camera and how it does what it does. Fuji cameras at their max resolutions have no digital zoom. As one selects lower resolutions, you get digital zoom, and as the resolution is lower the zoom is more. What the camera is doing is just blowing up the pic on the sensor - if you take a max resolution pic and a low res pic at max zoom and compare them, the low res pic is (exactly) a crop of the bigger pic.
Unless you need to zoom to frame an item, use the highest res you can and crop or enlarge it in the computer.
So let me get this straight:
I've got a 4MP camera - when I enlage this to 800%
on my computer screen, is the whole image now
interpolated up to more than 4MP?
Does interpolation mean breaking the image up into more
pixels than are on the camera's sensor - and guessing
which colours to fill in the gaps with?
Is interpolation a basic feature of digital processing?
Is there nothing unique about Fuji's super CCD technology
that they keep prattling on about?
Normally I shoot in Jpeg and optical zoom. As an experiment I tried TIFF and digital zoom. It looked a lot better. Don't know if it's the TIFF that made the digital zoom image better looking. Time to go play around a little more.
I've taken one or two decent pictures using digital zoom on my 2mp Olympus C-2100. However the digital zoom on my 4mp Canon A80 really produces garbage.
