Graduated Tobacco Filters are adapted to storm effects. They give a greater vitality to subjects in fashion photography & reportage. Graduated tobacco filters are available in five varieties. A124 - T1 graduated tobacco filter reduces the light 1 stop. A125 - T2 graduated tobacco filter reduces the light 3 stops. A125L - 2X Light starts with the same density as A124, but feathers the tobacco almost from the color edge and more gently graduates to clear. One stop of compensation. A125S - 8X Is the same density of color as A125M but the graduation extends to 3/4 of the filter. Requires 3 stops. A125F - 8X Full is the same as A125S except that the tobacco covers the entire filter. Requires 3 stop
