DIFFUSIONS (Diffusions - Cosmetics Diffusions): Spread the projected beam of light over the subject, some loss of light will possibly be seen. The greater the diffusion, the greater and more even the resultant spread of light. Shadows are reduced. Used to smooth out beam scallops when lighting cycloramas or in tight spaces.
FROSTS (Frosts - Coloured Frost): Frost is used for a variety of applications offering low to medium diffusion to a beam of light while maintaining the shape and beam centre.
