Can anyone inform me about options I may have for using my Tachihara 4x5 with a roll film back? I have interest in doing panoramas and without buying something really expensive such as a stand alone camera or modifying the Tachihara are their any options out there?

Also, what is the workflow for using 120 film on a 4x5. Like
6x9,
6x17?
6x WOW? What formats exist?
Determining just where on the GG to compose?
Can you make a view card to see the framing with out setting up the camera?
Any special limitations for swings or tilts?
Number of images a roll.
Getting scans or getting prints from a pro lab if possible? (Can not do color but would like too)

Any experience out there with night shot panoramas?

Thanks for any insights and lessons learned.
