Hi there! It´s my first time here. I don´t know if I should ask here but it´s so similar my issue... I´m a junior DP, I´m filming on Monday my first advertisment. We don´t have much money, though. I was really on a rush and had to resolve evrything today. I´m lookin for a cold and very soft light for this project. I´m having a HMI PAR 2.5 K ; 575 w HMI par; and some kinoflow. My quesiton is related to filters: I bought a roll of OPAL 420 (Lee) -is very thin! and half roll of Light Grid (Rosco 3060) and 3 meters of Half white diffusion (Rosco 3027) I´m not sure how to use this filters and the best way to organize them. I have also 4 1x1 meters frames. Could you please give me some advise???? I´m in a hurry and can´t buy or rent anything else!! I´m shooting on Monday!!! Thanks!!! P.S: I attach a reference for my lighting idea. It could be more bright though...
