Machine vision application of 8 lighting skills:
Tip 1: Detect material defects -- high brightness light;
Tip # 2: Pinpoint -- the right wavelength of light;
Tip 3: Detect scratches on glass -- non-diffuse Light, that is, No-Diffused Light;
Tip 4: Detect transparent packaging - Diffused Light, that is, Diffused Light;
Tip 5: Create contrast -- color light;
Tip 6: Detect fast moving objects -- stroboscopic flashes;
Tip 7: Eliminate reflection -- infrared light;
