To be Continued?

As part of an assignment I had done last year, I had photographed every surface my feet made contact for the day from the shower floor, to carpet to sidewalk, cement stairs etc... I then layered the photos into two images. One being the hard surfaces and the other the soft. I wanted to see if the textures could be differentiated especially since there was not an equal amount of hard and soft surfaces. I wish to continue something like this, perhaps where i do composite all the photos into one image to see what that gives me or to analyze surface texture in another way.
