Above is the original of a sunset on the lake. Below is the photo I adjusted. First I changed the levels. I then played a little with the hue/saturation. I really liked the way the photo looked when I adjusted the red hues.
When working with this photo I forgot to make a copy. :( So you can't see the original image. In the original there was no color other that white and brown. While playing with the hues adjustment I was able to make the green in the trees show up. I really like there color against the bland colors of the rest of the trees.
So, my daughter thinks out cat is one of her baby dolls. I captured this picture when she was pushing her around in her doll stroller. Amazing enough I think the cat enjoys it. This top picture is the original.
In this lower picture I first darken the background using the levels option in Photoshop. I then cropped the photo. I wanted to make the colors more vibrant so I adjusted them in the hue/saturation option. I lessen the red hue, increased the saturation and darken it a bit. I like how the colors really pop in this picture now.
