Still a newb learning my camera (Rebel XTi). I had a lot of trouble taking shots of the sunset, and people in front of it. I was wondering what the trick is. For the first problem (1st picture), the sun itself is overexposed, bleaching the sky around it to the point you can't actually see the sun. Through the viewfinder it was clearly defined. Secondly, everything else is underexposed, with a gold cast that wasn't observed in person. For the second problem (pictures 2-4), I tried all three metering modes, hence the three pictures, but they each had their own exposure problem. Maybe I'm not using the metering mode correctly, or something. Notice in the pictures how the subject is essentially a silhouette. How do I avoid that and get good exposure for both the sunset and the subject? Lastly, I noticed some chromatic aberrations (I think that's the correct term). Notice the red and green blobs in many of the pictures. What causes it, and how do I avoid it? I never had that problem with my point and shoot.
