So today I took my Rebel XT down to the canal to take some pictures. I'm still a beginner (got the camera in may). I'm still reading the book "Understanding Exposure" which was suggested here. It's great! I'd like comments on the following pictures. http://www.flickr.com/photos/8402955@N06/sets/72157600262589875/ The last three aren't from the same day but I'd still appreciate comments/advice on them. On the very last picture of the sky, there seems to be a lot of noise. How can I avoid this in the future? Using a low ISO resulted in a completely dark picture. Additionally, my uncle is going to give me his old lens. All he said is that they are from a regular film slr canon. I'll need an adapter to fit this probably, right? Thanks!
