Ken, surely adding a neutral density filter works. It forces your aperture to open up (see the video on La Foret's blog demonstrating the effect). But to call that 'control' is indeed a bit too much. It does have a great film-like effect when filming in bright daylight when you need a lower aperture though.





I thought that tip was nice. But I agree SO much: a true aperture priority mode for film on the camera would have been amazing. But I guess that's asking too much for 1st gen film tech in photo cameras.
