i'm writing to have the community weigh in on their thoughts regarding film speed with a location. i'm going to be traveling to a location that has relatively sporadic forest-shade and large areas of sunlight, making the choice of using a lower ISO film stock (100-400) the "easier" choice. When i experimented with higher ISO film like 800, during a a light snow and found that the grain issues with 800 speed film in daylight are less severe, than i had anticipated. i'm leaning into using 800 speed on my trip instead of the normal preference of using 160 speed. what are your ideas or views on this kind of thing and what might you choose to use in my situation?
