1. CUT ANOTHER VENT
Carefully cut another central vent in the middle of the upper lamination on the backside of the developed picture. This cut is invisible from the front and if it turns out that it will help to fight the humidity, we will also add another vent during future production runs.
2. PEEL THE IMAGE APART
Opening the image by peeling the positive and the negative apart will allow proper drying and avoids the development of the Killer Crystal. Turn your image over to the back, use scissors or a knife and stick the blade under the upper white sealed foil. Open it along the edge and repeat the action along the sides. Now open the image by removing the positive (front transparent foil) from the negative (the emulsion underneath). Don't peel too slowly but do try to peel gently.
3. PUT SILICA GEL INTO YOUR STORAGE BOX
Storing your pictures in a bigger box that also contains a fair amount of Silica Gel will control humidity below 40%. With every order of a PX 600 film pack you will receive one high quality Impossible Silica Gel. As a low-tech alternative to the Silica Gel, we have also had positive results using salt or rice as desiccant for PX film.
