Metering off...


Hello! I have a canon rebel GII that I got last summer and I have been taking a lot of pictures. Sometime, when I have taken portraits of friends, or other things, they have been over exposed or so I think, because they are lighter than they look in real life.

Check out http://photobucket.com/albums/v512/andrewsproofs/ and click on the album "Courtney."

Many of these seem to be too light to me. How can I fix this? Sometimes I'm just using "portrait" mode when it's bright out, but when the lighting gets lower I will switch to AV, TV or even M. I read that in the preset modes the exposure is evaluative I think it is. In Program, AV, and TV the exposure metering is evaluative unless I press the exposure lock. In M (manual) it said the exposure mode is centerweighted. Does that mean that just the center circle does the exposure work? Since I don't have the money for a light meter, I have to use the one in the camera so if I use manual I will try to set about the aperture that I want and then set the shutter speed I want based off of the exposure meter (-2,-1,0,+1,+2) to where the cursor is under the "0". Is this correct?
Another question, when people say to meter off the sky around the sun for a sunset, should I keep the sun completely out of the field of view unless I'm using manual for the "centerweighted"?
I know how when you try to take pictures of brightly colored things or of snow, they will usually be underexposed because they refect more light but is there a way to get around that without changing the exposer? One time I read about getting up close to meter a person but won't that mess up the exposure? Thanks! Please share any other know-how about metering using the TTL meter that you have collected if you can :)

  Assuming the prints are as light, it is probably your lab that is making the error when printing them (or scanning to CD-ROM). While not impossible, it's pretty rare for the in-camera meter to be this far off. Additionally, print film is pretty forgiving of exposure errors - especially overexposure - and the lab should be able to correct it when printing.

Alternatively, is it possible you've inadvertently set the ISO manually to a lower setting, or dialed in + exposure compensation?

Re metering - Partial metering measures only from the center circle in the viewfinder. Centerweighted is broader, taking in most of the viewfinder but giving greater weight to the center.

For sunsets, do not include the sun in the field of view when metering.

Yes.
(a) The Evaluative meter includes algorithms that sense an overly bright scene (such as snow in the background) and automatically compensate without the user needing to make any adjustment. But this program isn't perfect.
(b) Getting a close-up meter reading off the subject (without the snow in the viewfinder), or using the Partial Metering to do the same, will give proper exposure. This assumes, of course, that the subject is closer in tone to the meter's calibrated 18% gray than is the snow.

  so does that mean with my camera, maybe you can look up how my camera meters, I don't remember where it was, but does that mean that I don't have a way to meter off only the center circle if it said evaluative and centerweighted only? Thanks!

  The Rebel G II does have Partial metering. In the Creative modes (P, Av, Tv, M), pressing the "*" thumb button on the upper right of the back activates the Partial Meter and locks that exposure for 6 seconds. Pressing this button in Green Box and other PIC (icon) modes activates AE Lock only and not the Partial Meter.

  Thanks Jon! (you don't need to reply to this unless you want to since I assume you'll see it)
