one of my bad habits is using hdri background whenever I can and ignorantly hope that can beautify my render (they created an environment for reflection and also help lighting, is that good ?). In fact, some hdr give really ugly result, I attached here some renders made with different hdr lightings, as you can see, some of them are good, some are unacceptable (the noisy one). At last, some questions’ popped out from my head, how do you define a good hdr image for a specific scene ? When is using normal lamp rig better than hdr lighting ? Is hdr background the only way for reflection ?
All were rendered in yafaray with the same settings.
