The MD Histogram Plugin will add a new pane in DAZ Studio that will allow you to see the histogram of the scene preview in Iray or Filament mode without the need to render the image and pass it to an external photo application.

The plug-in will show you not only the histogram of the Iray or Filament preview, but it will also calculate useful statistic information like the average Brightness, the average Colors value, etc. The 256 px thumbnail screenshot at the bottom of the pane will show you the currently captured image, and it will also project the (clipped) highlights or/and the (clipped) shadows if you wish.

You don’t want information about the full image but just for a part of it? No problem! You can click and drag a rectangle on the thumbnail with your mouse and the histogram will automatically update the information only for the area you want. A special 'expand graph' check box will normalize the peeks of the graphs and an 'Exclude Color' option will ignore a specific color from the image, like the viewport background color, the backdrop color, or even a custom one.

With the MD Histogram Plugin, you can adjust the lighting of your render and fine-tune it before rendering!

The manual includes the scripting documentation if you want to use the Histogram pane in your scripts.

Beware: The plugin needs activation after installation. You can find the serial number, when you log in into DAZ page, under your “Account/Serial Numbers”. Copy the serial number and paste it into DAZ Studio in the popup dialog under the menu “Help/About Installed Plugins”.
