Some pretty good shots there, well done!
I suggest to anyone that you need to understand the basics and how they interact with eachother. Understanding aperture (f stops), shutter speed, ISO amongst other things, is really imperetive in getting your fundamentals of photography right.
scoota gal, when you refer to getting all the glasses in focus, Im sure you know how to go about it. The trick to understandin f stops is to understand that the number is a fraction.
f/1.8 is bigger than f/8, it lets less light in, it requires a longer shutter speed, but gets more of the picture in focus. When referring to things that arent in focus, theres a difference between something thats not focused correctly, and DoF (depth of field, or depth of focus) which is what youre referring to when you said OF (out of focus) at the end of your last paragraph. OOF is bad, DoF is good.
As for me, I learnt (well, were always still learning) on a Canon 20D. As for lenses, I have a 17-85mm f/4-5.6 IS, 50mm f/1.8, 10-22mm ultra wide angle, a 430ex II flash and a few other bits and pieces. Ill be looking at a 16-35mm f/2.8, 24-70mm f/2.8 and 70-200mm f/2.8 when I look at a Canon 5D full frame in 12 months time.. Quite an ugprade, and a kick in the pocket too
As for flickr, I dont use it..
