hi rahudman, thanks for the PM and request for critique ... nice snaps (great mountain ive skied there before.) ... but nothing special photographically.
im no expert! but my thoughts ;
What the others said about a polarising filter is very true, particularly on those bright blue days you can really tame the dynamic range and get brilliant rich colours etc (Cloudy days are another problem altogether.)
with regard to your composition you did say youre very fresh to it all (arent we all!) ... I'd suggest have a bit of a read about "rule of thirds" ... then try to remember it when you start doing more shoots. Also keep an eye on keeping your horizon level (this is hard i know ... the D70 grid will help lots.). On the one of your mate and you, I presume you didnt have any more zoom available? I always find with a "person" shot against a breathtaking backgronyud, tis still better to zoom in and have the person fill at least 50% of the frame, aswell as a section of the background as its really effective at showing the situation ... and it is a person shot afterall.
as for Circular Polarisers ... absolute MUST have. (theyre cheap.)
Also, find out the sweet spot of the lens youre using for sharpness, usually around the F8 mark ... use your camera in aperture priority
mode. Remembering that slows teh shutter speed, and if youre using a circular polariser, it slows it a further 50% so you have to have very steady hands ... or tripod use. (naturally if youre shooting action sports you wouldnt have teh CPL on unless you have LOADS of light, you'd be shooting in shutter priority
mode with the widest aperture available, to maximise the shutter speed ... so all depends what youre shooting basically.) That said, on a bright sunny day, if i KNOW that i have loads of speed even at F8, ill leave it on A priority so as to have maximum sharpness and be comformtable that camera will choose a fast shutter speed. ... but if its cloudy etc, then i'll stick on teh safe bet and keep the aperture set to widest possible, and most likely bump up to ISO400 if i really need to.)
Some snow examples, note the blue sky, allowing the foreground to be properly exposed, reduces glare adn allows much more rich colours, and massively widens dynamic range of an image.
(me skiing, mate took photos, he knows his SLR's)
my mate dave (he photographed me) .. me taking the shots now ;
action shots : try and get some refrence in the photos, and illustrate angles too .. easier said than done of course
