Late July I am going to be away for a week at San Diego's Comic-Con, and immediately after going to be at a friends beach house for another week. So I'm going to need to feed my hungry shooting finger and well in these times 10-20 rolls of Tri-x adds up. So I was wondering what other cheaper 400 ISO B/W films you guys can suggest? I have only used Tri-x because I devolop with HC-110 Dilution B, and dig the grain. Now what I have found is Arista Premium B&W 400 ISO 35mm x 24 exp. | Freestyle Photographic Supplies Arista EDU Ultra B&W 400 iso 35mm x 24 exp. | Freestyle Photographic Supplies Legacy Pro B&W 400 ISO 35mm x 24 exposures | Freestyle Photographic Supplies Foma Fomapan 400 iso 35mm x 24 exp. (Past-date Special 6/09) | Freestyle Photographic Supplies Now the Fomapan is very intriguing, but I have heard it is more like 200 ISO and just all round bad things, if anyone stands by this film let me heard you. The Legacy stuff I know nothing of, and the Artista stuff looks promising to me, but I cant for the life of me find a decent dev chart with more dev times for higher temps, and for pushing the 400 to 800. Lastly I am going to be using this cheap little underwater camera Snap Sights | SS01 Underwater Camera w/ Flash | SS01 | B&H Photo I saw some fliker shots of a guy who got lomo results out of some 100 iso slide film, but I was wondering if the 400 artista stuff would do, or push the 400 to 800, or lastly some kodak t-max 3200 and dev that at 1600/3200. I personally think the 400 may do since it has a flash.
