Color of dielectric surfaces
- based on physical surface colors
- real world average colors swatch of different surfaces
- no hard contrast
- no shadow
- no directional lighing
- no light reflections
- by using photo -> photograph only while overcast lighting to reduce directional lighting -> use a polarized lensfilter on camera to reduce light reflections -> use a colorshart on the photo to correct the color inconsitency + link background info
Color of metallic surfaces
- most physicaly correct results with flat colors
- based on physical f0 value of a real world metallic surface
- real world metallic f0 values swatch
- url background info about F0
