With more artists starting to use Blender Cycles to render architecture every day, a lot of interesting artwork produced with Cycles will appear Blender user forums such as BlenderArtists. This week I found an interesting example of this type of artwork produced by an artist called camara. He manages to create some really nice renders of interior scenes. The image that illustrates this post is part of the set shown by camara at the forum. And guess what? The artist shares some of his settings on the forum, which is a mix of strategic positioned light sources and a bit of postproduction.
If you are still learning Cycles for use on architectural visualization, this is an interesting resource to get some tips on how to achieve this kind of result.
