I don't think there is any question that a lens baby was utilized. The multi element lens baby of the newer generations can easily produce the areas of sharpness and clarity in his images. I also think some comments are correct that there may have been some degree of hybrid post production going on, although that is only a possibility. For sure over exposure combined with strong back lighting and some type of fill has been employed whether by reflector or flash. The bottom line is that he did not have much time to work in several of the images so I doubt he used any type of camera with swings, tilts or any quality perspective control quality lens. Looks just like lens baby to me and discriminately used.
