Being reintroduced to large format(4x5) I am curious about the results of color negative film for different subjects. I have used Agfa ultra 50 for 35mm negs a nd the colors can go from snappy to surreal.Great for flowers. But it isn't avai lable in 4x5. I also do general laqndscapes and lava photos at sunset or shortl y just after. (Yeah, I live in Hawaii) The vog (volcanic smog) is a serious prob lem for camera equipment and film. Also for your lungs. I like to get in, do my photos and get back out before the coatings on the lens disappears. Any suggestions on large format films in these shooting situations would be appr eciated
