    Zone V detail on Wedge

    I was trying to make my own gray-scale Wedge with 11 steps and decided to add a section where detail was present inside a zone.
    for zone V i took the value of 127 -+ 12 and ended up creating a brick/mortar pattern. I haven't tested this on film yet, but it seems that detail for darker zones seems clearer.
    Is there a better way to do this pattern? maybe darker zones should have less variance from the middle value....

    Thanks for any advice!

    Great idea

    This looks reflective. Are you planning on shooting it? A wedge is usually slange for a step tablet which is contacted.

    If you plan on shooting it, it will work well if you plan on doing copy work, but the luminance range of a gray scale is shorter than the average scene. There is a distinction between print Zones and subject Zones. Ten subject Zones has a range of ten stops or 3.0 luminance range. I believe the card is closer to 5 or 6 stops (1.50 to 1.80 reflective density range).

    I just plan to use it to establish film speed (ball park figures, exp film), and work on dev times with my developers. should I use reflective paper or matted?
    Is there a way to get more range?

    I like the idea, but IMO, the gray scale that is presented should be in keeping with a bonifide zone system gray scale, especially if references to zones are going to be your norm. I realize you are in the beginning phase of it, but for example, your Zone I contains way too much detail to be Zone I and the same for Zone IX. I would simply refer you to The Negative and the chapter on the Zone System and the sub-sections of "The Exposure Scale" and "Dynamic and Textural Ranges"------------it's all there and is easily understood. I've created the gray scale as described (after doing effective speed tests of course) and it pans out that way very well. Again, it's a good idea IMO.

    Thank you for the input. I do have all 3 A.A. books but I tried to have a single/simple subject I can photograph to test the film. He advices doing it with a wall/fabric. My goal was to print the card and use it as my exposure test. Having said that, the cards zone I has detail because we can see it, but will the film see it? That is precisely what I wanted to test. Else I will have to go back to shooting my bathroom wall 10 times at 2$ the shot...

    Good Lord! Establish zone 1 and find the processing for zone 8 and get out of the house. Intuitive sense from experience is the important thing.
