We are not trying to resurrect 55. We are trying to provide a high quality field processable negative system, such as 55 did provide.
If you want Panatomic X you can still order some in long rolls from Kodak, as it is still used for aero cameras. Otherwise it is not available any longer.
If you expect a duplicate of 55, that is not the goal. I am now using Efke 25 which processes quite well in reagent III which has been developed for the project. I think the two are superior to 55 in some ways.
The biggest opportunity is to make 4x5 more accessible to a greater number of people, and marketing it to a new audience of younger people just discovering 4X5.
