How I Designed This

about WISTA DISK

            <div><p>The zone system was invented by Ansel Adams and Fred Archer in 1941.<br>To practice the zone system, a photographer needs to determine the effective sensitivity of black and white film.<br>How do you determine the effective sensitivity?<br>With sheet film, the photographer must shoot several gray cards, changing the exposure.<br>With this tool(I named this WISTA DISK), a sheet of film can be given eight different exposures.<br>The photographer saves the cost of sheet film and development time.<br>However, we have some unfortunate news.<br>This WISTA DISK is probably only compatible with WISTA 45D or 45SP.<br>If this WISTA DISK fits other WISTA 45 (45,45N,45VX,45RF), please give me feedback.</p><p>Description of each part of the WISTA DISK</p><p>This WISTA DISK has four numbers engraved on each side. The numbers on the front are 1,3,5,7. The numbers on the back are 2,4,6,8.<br>When exposed, light passes through a small circular hole.<br>The four depressions around the disk are used to check the vertical and horizontal position of the disk.</p><p>How to use<br>step1: Place the sheet film holder in the revolving back.<br>step2: Separate the revolving back from the camera.<br>step3: Insert the WISTA DISK into the circular groove of the revolving back while bending it down.<br>step4: Adjust the position of the WISTA DISK so that the number 1 is visible in the upper center of the screen without tilting. 4 dimples are used to hold the tool in vertical and horizontal positions for easy adjustment.<br><a rel="nofollow" href="https://youtu.be/EAOPNfg6bsM?si=PldTYjhlm-XxHMaa">https://youtu.be/EAOPNfg6bsM?si=PldTYjhlm-XxHMaa</a><br>step5: Place the revolving back on the camera.<br>step6: Expose the image.<br>step7: Repeat step2 to step6 7 times. Note that the number in step 4 counts up from 2.<br>step8: After developing the film exposed in the previous step, you will get a negative with 8 circles in clockwise direction.</p><p>[Japanese]<br><a rel="nofollow" href="https://zonesys.blogspot.com/2024/04/wista-disk.html">https://zonesys.blogspot.com/2024/04/wista-disk.html</a></p></div>
