Default Flash memory cards for my new ski-cam?

I just got the Canon PowerShot A80 that others have recommended here, as
my first digi-cam. Plan to use it on a forthcoming ski trip to Montana.

Any recommendations for a larger flash memory card, specifically sizes
and brands? This is 4 MP camera, and the flash card that comes with it
is only 32 MB. Not sure I need a full 1 GB one, though.


Depends on whether or not you'll be shooting at maximum resolution.
IMHO, that's a waste unless you're planning to do 8"x11" or larger
prints; half that resolution still looks fine on a postcard-sized
print, and if you'll mostly be viewing on-screen, you can go a lot
smaller than that with no noticeable difference.

That said, I'd recommend 256 MB, and buy whatever brand is cheapest at
the moment. (A quick check at pricescan shows 256MB cards from Simple
and from SanDisk in the $45-$50 range - I've used both brands and had
no problem). I'm guessing you could fit well over 200
medium-resolution jpegs on one of those. If you want to be sure,
though, see how many pix you can fit on the card at max resolution,
and at a reasonable resolution, and then just do the math.


The trouble with that is that "the math" doesn't really work.

the photos will probably be stored as JPEGs (not sure about Canon, but
most cameras do), which means they will be somewhat compressed.

And ski photos probably get more compression than average, due to all
the WHITE :-)

I know that with my 4MP CASIO, set to 1600X1200 (about half max
resolution), I can normally (with portraits, landscape photos &
interiors) expect to get around a dozen photos from the 10Mb of
included memory, even though 1600 * 1200 is nearly 2 million pixels.


But the math would work to the extent that if you get about a dozen
shots from 10MB, you'd expect a 32MB card to hold about three dozen
similar shots (portraits, ldscp, interior), right?
