yes i do. jeff_someone is the person in the daz forum(sorry ren) but it is about helping people be their best-no?-. https://www.daz3d.com/forums/discussion/313401/iray-photorealism (sorry ren).
that is "photorealism", but not ~real~realism you don't have a bioflash growth. every image you have ever seen until recently, history wise; has been a photo; of some kind. now if you want 'realrealism' render your images in stereo.(pairs). without DOF.
