- install the lens behind or before a shutter (a big 'modern' one, or a kind of Packard)
- buy a Sinar with behind-the-lens shutter
- buy a Speed Graphic or any other camera with focal plane shutter (you may have much less movements than you would like)
Actually Thornton Pickard made shutters that can be used with Petzvals, either front or rear (beween lens and lensboard), they vcan be bought quite cheaply.
