Oh I do love these shots. I did one just recently at a local fair and I thought it came out okay though the kiosks below the wheel were a bit bright. I like the exposure here, it really brings out the colors...the pattern rather reminds me of those old spirographs I used to play with as a kid. Great shot.
Woahh... This one is seriously hypnotizing. I love the way you're experimenting stuff with your camera, cause I noticed people tend to prefer staying in the old fashioned way of pressing on the button when something nice's in front of you. This picture could have been ordinary, but you managed to make something really special and captivating about it, and that's what makes a photographer talented.
