No mentioning of any brand names here. One thing that really amaze me is why so many chose one brand of film over the other based on a marginal price difference.
Let's assume that you go on a photo backpacking trip on Saturday, you drive, fly, ride or i think rarely walk to your favorite place. If you shoot 35mm you come home with 5 rolls of B&W film. Perhaps the same in 120 format.
4X5 shooters will bring home on a good day 10-15 sheets and a 8x10 shooter maybe 6-8 sheets, just estimates.
According to my calculator the difference between some of the least expensive film and some from the 3 main manufacturers (We know the names)
it could be between 5 and 20$ depending on format.
Now calculate all the cost for the trip. gas, tires, food at a restaurant and anything else you spend money on. How much was the saving on the film really in the whole sceme of things?
In addition, Using film that have a greater risk of flaws could ruin the whole trip.
I admit that i use film from some of the lesser expensive companies but no longer for any "serious" work or work that is not easily redone. Use it simply cause i like to experiment with different results.
Film price should not really be the determining factor when it comes to picking a film. Just my opinion
