				When I bought my GVII It came with about 100 LBs of sheet film--average date 1945-50-----sealed in boxes never left cool office panatomic royal pan etc---
 
 
any experience on what iso you would start with and what developer---I know have a high base fog--but lets move pass that and decide on what combination would give me my best chance at some usable images
 
 
i was thinking pyro cat develop by inspection--maybe try an anti fog agent or restrainer and drop the iso to around 50 when exposing it |

				I came across some TriX with an expiration in 1984 in a bulk film loader.  After considerable testing with HC110 dilution H it produced usable images at EI 80 at 65°F.  The fb+f at 68°F almost equaled image density.
 
HC110 dilution H is 1:63 @ double the time for dilution B.
 
I would start testing at EI 50 but EI 25 or lower may be best.  
 
 
From the Kodak Professional Photoguide Publication R-28 revised 3-81
 
Royal-X Pan 4166 ASA 1250
 
Royal Pan 4141    ASA   400
 
Panatomic-X/ Panatomic-X Professional ASA 32
 
 
The film may be worth more for its antique value in factory sealed box than it is for image quality. _________________ The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU. |
