I would have to see a couple shots. But yes I have had several projects where "well we thought an ND would help", some on ARRI 444, some on RED, even some on film.

Trying to come up with a solution for this major issue in a feature 
that I'm corrently grading. Due to use of ND filter, a lot of material 
presented major color shift ( blacks, and some blacks only, fabric and some 
clothing) are getting this purple eggplant grapeish color that I'm unable 
to remove on primary. On secondary and carefully selecting the clothe 
affected, I do get some correction, but quality is no good to me. The 
material is on 444 .mov from alexa, so no .ari to try to fiddle with color 
temp, tint., etc... Does anyone have a recomendation for me? IF.. and only 
if... it was shot raw do you think some thing could be done? 

Thanks all for any input
