hi mat,
thanks for your suggestion. but it's 500T Vision 3 stock. so it's super fast already.
in terms of fooling the camera, i've learned to do from what the ambient spill from car headlights taught me. when i was shooting stars at night, i simply passed a pen light over the sensor, which advanced the shutter/frame without exposing the film.
so that's my down and dirty manual advance. i was just wondering if there was a mechanical way.
i'll check out
