Does anyone know if it's possible to control the shutter in such a way to do multiple exposures on one frame?
When I used to use film to shoot fireworks, for instance, I would hold the shutter open and have a black cloth over the lens. When I wanted to capture something, I would remove the cloth for a few seconds and then recover the lens, waiting for the next event.
Hope that makes sense...
I suppose I could use the MD script and then combine photos in Photoshop or something, but I am just wondering if it's possible to do programmatically with a remote, for instance.
