hahha u and ur salivating..
anyway a 1D is a bit old liow.. if he had the 1Ds which is full
frame then ok steady.. there's only 2 full frame dslrs out there
now. if u're talking about the 18-55 EF-S lens that comes as a kit
with the 300D then it wouldn't fit on the the 1D...
anyway bis buddy, u need to get a very fundamental attitude right.
let's reverse the roles, and say u struck lottery and bought
yourself a full frame Canon 1Ds and a Nikon D2H as backup, using
ONLY L lenses for the canon and AFS f2.8 fixed aperture lenses for
the nikon, do u think u could take better pictures?
also, if u really had all those equipment, would u look down on
someone, (say me?) becos i only have a cp5700? would u decline to
take my camera and help me get a snapshot of my joyous moments in
melbourne with some really nice pple?
sometimes we gotta remember photography is not about photos. it's
about capturing a moment. a moment that will bring a smile to your
face when u open it in ACDSee or when u flip thru the album. the
photo could be yellowed with age, but u will still smile in ur old
age. at that time, does it matter if u took the photo with a lumix
or with a 1Ds, or even a disposible cam from the newsagent?
hope i haven't been too harsh, but if no one tells u this now, u
will never be able to take good photos, becos u will never be able
to have the best equipment. not becos u won't be able to earn that
money, but becos equipment can ALWAYS be bettered, attitude, not
necessarily. 
OK! enuff of that... now to ur polarizer question.
to get the bluest sky, do a thumbs up with ur hand and point that
thumb to the sun. now open and close ur palm with the thumb still
pointing to the sun. the area that your fingers "sweep" the sky is
the part where it will turn out the bluest. (90 degrees plane from
direction of sun) if the sky is cloudy, then go shoot urself or
something 
now, be careful with the polarizer when using wide angles, becos
with WAs u can catch ALOT of sky in ur frame, so there will be some
parts of the sky that are REALLY blue, and other parts that are not
(as in not part of the "fingers" when u open and close ur palm).
this might result in a very unnatural photo becos of a very
contrasty sky (very deep blue vs very light blue)
of course some photographers have made use of this effect to their
advantage, it depends on what u're after.
also, NEVER use a polariser with flash, firstly u lose 2 stops of
light, secondly some of the light will be filtered away.
and if u must stack filters, put the polarizer last, but be careful
of vignetting.
eh.. i think that's enuff for polarizers from me for now. to be
honest, i can't remember the last time i used mine. prob in
australia. in sg, the sky is either too sh[/i]it or too cloudy, i
rather not lose my 2 stops of light and get more contrast with
photoshop!
