I have heard such good reviews of Freestyles EDU sheet film which is Forma 200 I decide to give it a try. But being cheap by nature and circumstance, shooting dozens of sheets 4x5 film to find my zone I and VIII makes me wonder if there isnt a better way . I considered exposing for Zone I with the 4xz5 sheet film holder in the camera and then slowly sliding the dark slide down effectively masking the previous exposure and repeating the same exposures thus creating Zones II ,III,IV etc. However I remembered something from my old days of color separating and masking that accumulative exposures did not produce linear density changes. Assuming no flare (good luck) the second zone I exposure would not necessarily produce a Zone II density equal to a separate zone II density exposure etc. Not only that but it is still winter and shooting outdoors in sunlight is pretty much months away! Anybody have any experience or ideas on this?
