I was deliberate in my approach but, alas, not very technical. I knew that I wanted to do longer exposures, so I guesstimated at 3-5 seconds with the film and filter set up...The additional variable was that I'm a novice, non-technical printer too..started at f/8, did test strips and sha-zaam!
Print is lighter than I "previsualized" but I'm sorta happy with it.
