Truth: Many images on Houzz may at first appear as renderings when seen as a small thumbnail, but they lose that characteristic when seen larger. Images of the Lookout House, though, may fool the eye at any size. In this exterior view of the poolside, a combination of HDRI (High Dynamic Range Imaging), in which various exposures are overlaid into a single image, and a softening in Photoshop, result in an image in which real surfaces look virtual.
