Excessive contrast comes from too much exposure, or too much development, or both. This used to be called "soot and whitewash". One of ortho's biggest advantages, from a use standpoint, is development by inspection. Under a ruby red light. If you use too powerful a developer, the neg will flash up so fast you can't control it. Dectol at 1 to 1,or 2 to 1, Rodinal at 25 or 50 to 1. When I use dectol, I use it at 25 to 1. Or Rodinal at 100 or 200 to 1. This takes 8 to 15 minutes to fully develop. I try to get it closer to just less than 10 minutes by strengthining the soup. Now filters. Ortho film is very, but not completely, blind to red light. It is extremely sensitive to ultra-violet, or in other words, skylight. When you use a 2X yellow filter, it holds back the u-v light in the sky, permitting a longer exposure. This allows cloud detail, and more shadow quality. Now I can't tell you which Wratten filters are which, because I use Burke & James "Ideal Ray Filters" If you can find them (on e-bay) they come in 2X, 3X, 4X, and 5X. The last two are almost never seen, so if you can find a 2X and a 3X, you're in business. I suppose everyone knows (or, as a Russian friend of mine says "as every hedgehog knows") That the "X" tells you how many times to multiply the exposure. I've heard that a green filter will work too, but I don't know if it will because I've never had one. Now, I'm sure some of you are staring at this little epistle, and thinking, "Gee, if I would just step up to the pump and pay five or so times more for pan film, my troubles would be over". You think so, right? The answer is, if all you want to take is snapshots, yes. You really should use a light blue filter on pan film to darken the reds. They put an excessive amount of red dye in pan film because it gooses the speed way up there. In conclusion, use ortho film for it's superior qualities, and pan when you have too.
