X-mas holidays and time to experiment with pinhole.
My second home made camera uses roll-film and gives a negative size of (almost) 6 X 9 cm. I've done some shooting at home with kodak tri-X (the new one). The correction for reciprocity suggested by kodak requires an adjustment in development that varies with the exposure and is difficult to apply if your time varies greatly from shot to shot. I've applied the exposure correction but developed the film with my usual tri-x time/developer/temperature (i.e. ignored the development adjust). The negs I've obtained are a bit too dense in the long expositions. Does any of you can point me to set of correction values that do not requires to adjust the development time?
