Nodes - Phong, Lambert, Anisotropic and Blinn

This is a comparison of the nodes within Maya. It was to understand nodes more, I used four bowls for this. I added a light above and a low intesity light below.

Phong should be useful for glasses, as when in light, there tends to be spots of glare, the light appears to be more concentrated in one area. this appears in certain plastics too, and ceramics, but only in light of course.,

Anisotropic is most luminescent of the four here. Blinn in comparison reflects less light therefore allows more detail to show through. The brightness in Anisotropic is quite dense, it'd be best used somewhere with extreme light.

Blinn, although similar to Phong, will likely be in direct sunlight, or near a room light. The light doesn't focus in as much on one area like it does with Phong. I would say Blinn is good for water, it is strong and it spreads the light across the surface.

Lambert is the dullest of the lot. It looks like it's old and/or matte in colour. Wood for example would be suitable for this node. Dirty objects also will be best fit for Lambert as the layer of dirt in whatever object it is will prevent reflection from the light source. Cardboard is also effective.

I am still learning more about nodes and which materials they best fit in a real world environment.
