Have you ever thought about how different lighting can change the color you see? Yeah I didn't think about it either. At least not until I took my photography class. Now I know, light sources make a huge difference.
I guess I had thought about it a little because in my house, I use CFLs which produce a different color than incandescent bulbs. I decided to play with the white balance (which is normally just on auto) in my camera. Look at the difference.
This first photo was taken under the incandescent setting. Notice the blue look it had to it? That was not what I was looking for.
This next photo was taken under the fluorescent setting. This looks way closer to what I was seeing when I was taking the picture.
This was taken under the shade setting. This is my favorite out of the three. I also happen to be holding the camera a little more straight in the picture, which is always helpful. (I really want that dang tripod!)
I still have a long way to go before my pictures look professional, but I'm definitely learning!
