Newbie Alert: 'Understanding Exposure' Question

I recently invested in a 30D as an entrance into the DSLR world as well as purchased Understanding Exposure by Bryan Peterson after seeing hundreds of recommendations from POTN. I am reading the book now and learning a lot about the triangle and getting an excellent idea of the trade-offs of each to get the correct exposure (I mean... creatively correct exposure) ;)

There is something that I find rather confusing and I am not sure if I just missed it in the beginning or what. For every example image there is in the book, he always says something like "I aimed the camera at _____ (insert something about the environment here) at ___ shutter speed and adjusted by aperture until the camera meter indicated ___ was correct."

For the 30D, is the meter the tickers you see at the bottom when looking through the viewfinder? For basic shots on a sunny day - is it the point to try to get compensate to get the meter to point to 0 (center) ?

Thanks... I warned ya about the newb alert. :oops:

yes, assuming the meter is correct.

the meter is measuring the light REFLECTING off the subject. it wants to render that 18% gray(midtone)

so if the subject is black, it will over expose it and likewise if it was white it would under expose it. So you have to know when to compensate in each direction

It works that way for film, but digital has another factor to take into account.

Dude,
Getting exposure right(i.e. getting it the way you want the picture to look) can be a challenge regardless of whether you are an amateur or a 'pro'...
i think this article would explain a lot:
