Theta S ND filter

This is ND filter for Ricoh Theta S panoramic camera.

Which is a variation of Lenscap I made before.

Of course this limits over harf area of the picture, but if you composite the pictures into HDR, anyway such darker areas were cut out, so the limitation has no effect on final HDR image (41 MB).

Also with the 32 bit true HDR, you can make such movie in 3DCG software like CINEMA 4D.
