Even with the entire buzz around Blender Cycles these days, there are still a lot of artists working with architectural visualization in Blender and rendering their scenes with either YafaRay or LuxRender. You may remmenber suomi from the YafaRay user forums, which is a very talented artist that uses Blender to create architectural renderings. He posted the image that illustrate this article a few weeks ago at the forums and just like his previous works, suomi was kind enough to share his render settings in YafaRay for this scene. If you want to learn how to get this kind of quality in render using YafaRay this is a really nice starting point.
To know more about suomi work, you might want also check out this interview with the artist about his work on architectural visualization.
I, for one, still find that Yafaray, in the right hands, produces the most appealing results.
Thank you sir for this article.
