How was your FT-012 3D lens modified? I have 3D printed an adapter that slips over this lens and with 52 mm (can also do 49mm) filter ring to accept filters or better yet a +4 or +5 Achromatic close up adapter lens from Kenko
Thanks Robert! This sidebar is a 5mm rod Size original for Gopro. 20cm 8 inch fotr the best results.Distance closed object 6 metere but objest are not too small. Fingertriggered syncron. Loud beeps by GoPro for control
I would rather say that because the boat is blue, it creates a big exposure difference in BW conversion. Furthermore the surface is large making it very noticeable. I noticed similar effect on red parts in other photos.
