Image Control: Motion Picture and Video Camera Filters and Lab Techniques, Second Edition which gets into this. On top of that you will need to make some tests to understand how the filters work for you.

Now of course optical quality won't be that great on a "home made," filter and I don't advocate trying to make your own 85; but go nuts with diffusions etc; never know what you might cook up.

I don't know if these truly count as filters, but I know some photographers and DoPs that have/had their own collection of different kinds of ladies stockings to stretch behind the rear element of the lens as diffusors.

am i right ? i have seen my seniors change asa in the meter to compensate like if they are using nd3 in 5201 stock they will set 25 asa in meter and keep the exposure for 25 asa
which is easy & safe ????
