Hello

I need to eleminate the ambiente light.
Read about what if you use a circular POL-filter together with an linear POL-filter
you get a variable ND-filter ( up to absolut darkness).

It works...but I get a heavy blue-color overlay - which I can controll with RAW-colortemp. changes.

Should I try an other combination of POL-filters?

At last a exanple shot:

with POL:
