Daniel Xiao is a concept and matte painting artist who has worked for Pixar Animation Studios, Dreamworks Universal and Fantasy Flight Games, among others.
Xiao paints digitally in Photoshop, as well as working with 3-D applications like Maya and Sketchup Pro.
His fantastical landscapes have a wonderful sense of scale and atmospheric perspective, the qualities of which don’t really come through in the small images I’m showing above. The visual appeal of his work is much more evident on his on site, and even more so on some larger selections you can see in this post on Concept Ships.
Xiao also has a blog that features additional images and work in progress.
On his website you will also find images of digitlally rendered naturalistic landscapes, still lifes and studies from artists like John Singer Sargent.
