Personally I leave my camera set to 640x480 most of the time, though
it can do 1024x768 (1.3 megapixels). That's all you need if you're
just going to post it on the web. Higher resolution (i.e. more
megapixels) is only needed if you want to print the pictures on paper
or show them on a monitor locally - for the web, they're too big (in
terms of bytes).

Actually digital zoom is just cropping done for you by the camera. It
takes the picture using its highest resolution but then crops out the
outside edge. That's why digital zoom pictures can not be made at the
maximum size. But optical zoom adds considerably to the price, so you
need to decide if it's important enough.

Most cheap cameras are fixed-focus, but have "tree" and "flower"
settings, which affect the exposure. I can take close-ups in "tree"
mode but the colors will be off.

Depends on how technical you want to get. My camera has the
tree/flower setting and several flash modes, and that's enough for my
purposes - I get much better results with my digital than I do with my
old manual-focus Minolta SLR's.

I use Rayovac Rechargable NiMH batteries. The 1600 mAh AA batteries
work great. I can use Duracells but they'll only last about two shots
before being relegated to flashlight duty...
I would also add: get a camera that uses SmartMedia, CompactFlash, or
Memory Stick chips. Don't rely on using a data cable to transfer
images. Get a PCMCIA adapter for the memory card and you can use any
laptop to download the images, and it's even faster than USB. Also,
with the USB cable to the camera, you have to install software on the
computer, which limits your ability to download pics into someone
else's computer. And buy a big memory card to supplement the one the
camera comes with, so you can go longer between downloads.
Caveat: my camera is an Olympus D-360L and it's a couple of years old,
so I'm not sure what the latest technology offers...

| (...) Well, not always. What I ment is that, using high resolutions, you can, in effect, do a 'digital zoom' on an image-editing program. For example: (URL) took a 2048x1536 picture, then cropped out a 640x480 section, which held a monkey. The (...) (22 years ago, 24-Dec-02, to lugnet.publish)
