Wild Sunflowers or Learning to Use My Camera

I bought a new cameral last winter but haven't spent much time learning about it. I bought a Canon S3IS mostly for it's optical zoom of 12x and its image stablilization. In the winter we have a lot of bald and golden eagles and I want to try my hand at photographing them. Needless to say, I didn't do that last winter so I'll take my 365 challenge as an opportunity to learn my camera.

In reading the instruction book I discovered I can highlight specific colors in my picture. Now how I took all the yellow out of this sunflower, I don't know, but it sure looks different, doesn't it?



This shot sure highlights the color of the flower. I like how the background disappeared. Again, I'm not sure what I did to get this shot.



And this one... well, I really like the yellow dots inside the flower. I don't know anything about sunflower anatomy so I have no clue what they are.
