Photo 1

I think McNally started with a base image and placed the other pictures on top of it to form a new but similar image. The pictures were transformed to the desired size. I think there are at least 24 pictures in the overall image. all the photos were taken at different times of day. You can tell by the lighting and shadows seen by each individual picture. Some photoshop enhancement I see is blurring of the images. Not all the pictures are blurred the same however. I think blurring some images and leaving some with high resolution was a great idea.
