No.5 was originally taken for experimental purposes, I was going to mess around and do one of those terribly cliched B&W photos with one color object in (guess which house) but it turned out so nice I think Ill just keep it as is.
Regarding the cable in 3 Im not a big one for major PS work on photos. Experimental stuff like tilt shift or color changing I do more for messing around. Editing a photo to make it look "just right" by removing objects is something I dont believe in.
