HORIZON FILTERS

[Regis <regis@xxxxxxxxxxxxxxxxxxx>]

Hi,
I am a newcomer to the field of panoramic photography and to this mailing
list. Perhaps, I should quickly introduce myself. I'm 28 years old Swiss
3rd year Ph.D student in Physics at the Uni of Sydney. I have been enjoying
35mm photography for 4 years. I have a 20mm lens, but I like so much
panoramic images (not just the format, but the angle of coverage) that I
recently bought the Horizon 202. I can't wait to shoot my first roll. 
Should I start right away with slide film (I usually shoot Velvia or
Sensia) or master the technique with print film first ? More generally, my
aim is to blow up shots using this camera. So, should I solely shoot with
print film ? 
Now, if I shoot with slide film, do I have to buy a special projector ?! 
Finally, is it possible to fit a polariseur filter onto the lens ? I
browsed Willem-Jan Markerink website, but I didn't find any information on
that. Should I change my glasses or there isn't really !?
Well, that's enough for today I think...That's all folks ! Ragh, I love
these cartoons...
Thanks for any answers.
