Earth & Eye exercise

For the earth & eye exercise, we had to turn a picture of the earth into the lens for an eye, we loaded the two pictures on to photo shop then put the full picture of the earth over the picture of the eye with the move tool. We then put them on different layers, then using the oval marquee tool around earth, then we used inverse so the space around the earth image gets deleted. Then we change the earths size to fit around the pupil, and the last thing we did was blend the earth into the eye by using the layers palette and selecting overlay and will blend the earth into the eye to make it look like an eye lens.
