How'd we go from 3 newbie questions to the perennial debate on
proper technique? I have /no/ trouble with camera shake with
flash or in daylight, and never have except when I shoot the
Woodward Dream Cruise pre-cruise event at sundown. And, I
haven't had the time to test my new toy at high ISO and see
what shutter speed I get, so the question is moot. I
understand IS and the First Amendment gives me the right to
ignore it.

I said a lot of complementary things about this NG, and you
David. But, I neither need nor want a Photography 101 lesson.
I am well aware of all this stuff, I've been take 35mm for 40
years and digital for 5.

I used to shoot at 1.6 MP, then went up to 5 but resized down
to 3 in PSP 9 prior to editing. I used to save at 1280 x 960,
not I usually go 1400 x 1050. Is that OK with you if I still
do this with my new Canon? I certainly hope so. <grin>

What is your issue with what I choose to do with my images? I
know about the "rule of 200 PPI" and for me, it is bunk. I'm
not going to debate this any further. I now know the answers
to the 3 questions I asked, I have a modicum of experience
with the XT, and I'll come back with more questions as they
come up.

See my sig, it says it all here...
