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.

Transmission Projection (TP) Step Wedges are most commonly used in the enlarger to establish exposure and processing adjustments and to determine the speed and contrast of photographic papers. 

Stouffer Picture

Visualization is a creative and subjective concept used when approaching the art of photography. Visualization works by projecting the final photographic image in the mind.

To help the photographer use this creative concept, Stouffer has designed the RZ9 Zone System Chart. The RZ9 displays the useable Zones of I to IX for comparison of the actual tonal values of photographic papers and images to be photographed.

Transmission Projection Step Wedges available:

Following the concept of the RZ9 Stouffer has designed the WBZ9 White Balance Zone System Chart to help achieve the proper white balance for any lighting situation. Side one represents Zones I, V, and IX in three large steps of reflected density. Use this side to set the custom white balance of a digital camera. There is also a 9 step Zone System gray scale at the edge of the chart to help visualize zones I through IX. As an added bonus there is a full sized (18% gray) matt, gray card on the opposite side.


On location or in the studio a photographer can photograph the White Balance Zone System Chart, filling the frame with the three zones, and metering for Zone V. This helpful chart offers a well balanced exposure of highlight, mid-tone, and shadow to use as a reference point for custom white balancing.


A photographer can also capture the WBZ9 at the beginning of a shoot or as often as needed for different lighting conditions during the shoot. The WBZ9 can then be used as a curve to adjust each image from any series of photographs with the same lighting characteristics.
