DSLR Owners Unite! (56k? Are you kidding me?)
You beat me to it. Haha. I was going to say the same thing, that using an SLR really brings you back to the basics. You really have to take your time when you compose a shot, because your not able to check if your highlights are blown out or if it's underexposed. Plus, looking at the film for the first time a week later is more exciting than you would think. Haha
something i've been intrigued about lately is how the level of zoom changes the size of things in your background.

18mm

60mm

95mm

170mm

not that it's rocket science or anything. but i imagine learning how this changes your photos could really help people looking for a specific shot of their subject. i guess more important would be actually retaining the information for when time is very limited and you have only a one-chance photo op and you don't want to guess wrong. i dunno just found it interesting. something i'd like to keep in the mental toolbox. maybe this helps someone out there.

Snow, yeah it's called Compression and expansion. Also works with DOF. the longer the lens the shorter the DOF will be at the same aperture.
Now can anyone tell me why a lens is the aperture it is (cause lenses are different sizes and some how have the same aperture value)?

is there an equation out there for DOF compression? like say 35mm @ f/2.8 will have the same depth as 180mm @ f/5.6. something like that would be interesting to test out.
there are DOF calculators. Compression is different from DOF tho. It's always good to know that a wide lens with expand ur background and a longer lens will compress (smoosh) it. Like my 135L is AMAZING at creating smoosh haha and a 16-35mm lens will make a landscape look like it goes on forever.
