I've just mentioned your very interesting timelapse tutorials in the BlackBoxGlobal FaceBook Group in a starting thread on "Holy Grail" timelapses.

The group was recently "closed" but you can still engage in the group by becoming a BlackBoxGlobal member or just FB-requesting to become a member of the FB-group.

For fast BB approval you can use my referral link or apply for BB yourself of course.
BlackBoxGlobal suddenly had an avalanche of new members; in the month of June membership grew sevenfold, we're still "recovering" :-)

Holy Grails are to difficult for me, I rather shoot twice with and without ND and crossfade in post, but I always love to see the experts being successfull at this :-)
