A graduated ND filter is also going to darken the fireflies as well.
Graduated filters are only useful to change PART of a scene... top.
bottom, left or right. What is needed here is to darken all the
background and allow the fireflies to remain the same intensity.
I suggest you wait 20 minutes till it just gets darker!
