Bright Field and Dark Field Lighting

Understanding the "W":

  • Reflected: light is the same angle as the source
  • Bright field: light is reflected into the camera
  • Dark field: light is reflected away from the camera

Bright Field Lighting:

  • Good for high contrast but specular reflections on shiny or reflective surfaces

  • Rule of thumb: Light should be twice the field of view at the camera lens

  • Avoid “hot spots”: Diffused light source provides even illumination in the brightfield

Dark Field Lighting:

  • Diffused light is reflected into the camera; specular light is reflected away

  • Light source is outside the “W”

  • Light is reflected away except for textured surfaced and elevation changes
