A problem has arisen for us in regard to 35mm film. Previously we kept some films in our “limited space” in the caravan refrigerator, purchasing fresh film when restocking our general supplies. But the 2007 trip in particular we found replacement 35mm film mostly limited to Fuji 400, with sometimes Kodak 400, but no other speeds or quality available at ordinary outlets. At the camera suppliers in the major towns where there are overseas tourists the price of films can be quite high! So we have been keeping greater stocks of film, stored in insulated bags in the van, which is also the way we store the rolls of exposed film, and immediate reserves in the four wheel drive.
With ambient temperatures often around 40c and inside the parked vehicle 50c, I have been concerned in regard to effect on both un-exposed and exposed film, and not prepared to risk purchasing some of the very expensive higher quality films, which I feel would do greater justice to the types of photography available to us, but would of necessity have to be stored for months at a time in the caravan. I have had a higher than previous failure rate on developed images from the 2007 trip, which although probably my fault, film storage temperatures could also be a factor.
