The Stouffer TX Exposure Guide is used to pinpoint the proper exposure for B/W and color prints. From one test exposure, the user can select the best of the nine exposure patches that cover a range of 1 1/2 to 3 F-stops in 1/6 and 1/3 F-stop increments. A conversion chart indicates the proper exposure in seconds.
