here are two picture that i altered using photoshop. i have to admit that photoshop is still pretty much a forign language to me. in the picture of the two people in the cave, i increased the saturation of the water to bring out the green-blue color a bit. i also brightened up the man on the right and increased the contrast somewhat. on the landscape i felt that the upper lefthand portion of the picture was underexposed so i darkened that up a bit using the lasso tool, and adjusting the brightness and contrast. i also increased the saturation of the whole picture to bring out the actual colors a litte more. lastly i used the paintbrush tool to play with the shadows a bit.
