Photoshop is such a powerful tool it's almost hard to comprehend it's capabilities. It isn't some all knowing, omnipotent being, but sometimes it sort of seems that way. I'm continuously trying to learn more about Photoshop and develop my skill set with it but I feel like even with years of practice I'm only barely scratching the surface of the potential that Photoshop holds.
Using Photoshop gives you a God like sense of control with the ability to create. You have the ability to bring to life your wildest imagination, if you have the experience and the skill set, which is why it's so much fun to learn. The better you get the more real your creations can become, from compositing multiple images into once fantastic scene or blending multiple elements together to create a photo realistic interpretation of the world.
Here are some things that I've been playing around with lately. Just some fun little projects to stay fresh and get some practice in. Hope you enjoy.
