As part of my series of basic portrait retouching techniques, I want to give you some options on whitening teeth—Photoshop options, that is. I’m not here to sell you white strips or bleaching trays. In fact, I don’t want photos that end up with fluorescent blue/white Regis Philbin teeth, just something realistic and a little less yellow Introduction
Create a new letter sized document. Use the Rectangle Tool (M) and create a rectangle 36 px wide by 216 px tall.
With the rectangle selected go to Filter > Stylize > Round Corner to bring up the Round Corners dialog. Change the Radius to 11 px.
I use my diamond models but you could just use the Hedra primitive (Create > Extended Primitives > Hedra) to create some jewels in seconds. Just create two Hedra objects and place them on a Plane object to create something similar to my scene. Change the color of the Plane object to white. Create a camera and make sure that you don’t see the edges of the Plane object in the view. Change the size of the Plane object when necessary.
The following article isn’t intended to be a tutorial as such but rather a focused ‘making of’ during which I will attempt to explain a lot of my working practices and techniques. I’m going to illustrate this with Videos and images where appropriate. I’ve also included at the bottom of the article a link to the scene file, which includes a version of the scene with a frozen mesh and all the textures in JPG format at full resolution. I have no intention of discussing modeling or sculpting techniques, as there are already thousands of head modeling tutorials out there and I really don’t think there is anything I can tell you that you wont find better demonstrated elsewhere. Instead I want to focus on the Texturing, Shading, Lighting, Rendering and grading of this image.
In 3D graphics cell shading (also called cartoon shading or toon shading) means a material / rendering method that produces to a result that looks like a hand drawn picture. The purpose of cell shading is to create a rendering that looks like cartoon or comic book style.
In this cell shading tutorial I cover a method of doing cell shading in 3DS MAX with the scanline renderer. Of course cell shading can be done by using Mental Ray’s Ink’n Paint material but in this tutorial I concentrate on a method that is very fast and works with both scanline renderer and Mental Ray.
Human head is one of the most difficult subjects to model believably. The structure and form of a human face is so familiar to everyone that even a small fault in the 3D model is easy to notice.
I saw few Illustrator tutorials in the web, but i didn’t really like the final image, so I had to think and find the right way for drawing a more realistic disco ball… If you are interested, please see below the instruction 
Create a New Document and then create a rectangular shape (I choosed ~ 175*175px). Fill it with bright radial gradient. Rasterize your image. In the top menu go to Object-Rasterize and just clik “ok” not changing anything there. Then enlarge your square a bit (~150%)
