Worst: chapter 11 and then liquidate everything to the highest bidder under the supervision of a court.
...and for film shooters as a group:
Best: Kodak goes and their film market share goes to companies that can extract more profit per unit sold. Prices remain fairly stable.
Worst: Kodak goes and takes out all the remaining local processing with it, raising the effective cost of using film beyond the reach of newcomers. At that point, only those with film projects underway and good stocks of film and chems will be financially viable.
