Hockney inspired collage

I shot this in class to discuss Hockney, Photoshop, and resolution. Keeping at the original 18 megapixel images shot with the Canon Rebel, and keeping the multiple layers, this image was over four gigabytes as a RAW file. That requires a lot of processing power and a lot of memory. The old computer we had in the classroom, which is really just for simple web tasks but has Photoshop CS2 on it, could not realistically deal with it. This version is obviously shrunken and compressed (less than one meg).
