Instructions for Metrix Plug-In

Please Note

Each year's version of Metrix expires on December 31 of the year. To keep using it after the end of the year, simply download and install the current version from this website.

Extracting Metrix

Open the downloaded zip archive,, and read the text file called Extracting, Installing, and Using Metrix.txt. This text file gives you the password for extracting the Metrix plugin (which is Metrix.8bf) from the file. Extract Metrix.8bf. Quit your plug-in host application (e.g. Photoshop). Remove any old versions of Metrix.8bf from the host's plug-ins folder. Move the version of Metrix.8bf that you just downloaded and extracted to the plug-ins folder Then, re-start the host application.

Installing Metrix

You can use Metrix with Photoshop or any other graphics program that supports Photoshop plugins.

If you are running any 32-bit installation of Photoshop, you'll need to install Metrix into the Plugins folder for the 32-bit version. You will find the Plugins folder for the 32-bit version of Photoshop in "Program Files (x86)\Adobe\Photoshop [your version]\Plugins."

If you have the 64-bit version of Photoshop but not the 32-bit version, Adobe lets you install Photoshop 32-bit for free for any version up through Creative Cloud 2015 by following this link: Similarly, if you are running any 64-bit version of Paint Shop Pro, you can also install the 32-bit version. Here's the link:

You can also use Metrix with the 64-bit version of Photoshop or any other Photoshop plugin host like Paint Shop Pro. To do this, you need to install the free trial version of AlphaPlugins LaunchBox, which includes the AlphaPlugin 32bit Bridge plug-in. It's available here: The plugin folder for the 64-bit version of Photoshop is "Program Files\Adobe\Photoshop [your version]\Plugins."

Depending on your operating system and configuration, you may need administrative privileges to make changes to your plug-ins folder.

After installing, you should see Metrix listed in the "PSI" sub-menu of your Filters menu.

Using Metrix

1.    Metrix works with 24-bit RGB images (8 bits/256 levels per channel). Convert both images to 24-bit RGB if necessary. (Also, if the images come from different sources, make sure they use the same color profile, using the Assign Profile and Convert to Profile functions in Photoshop's Edit menu.)

2.    Select the areas of the images that you want to match.  For a panorama, this will be the area of overlap:

GC-L-Dem.jpg (16402 bytes)
GC-R-Dem.jpg (18209 bytes)
post-sel.jpg (26732 bytes)
pre-sel.jpg (25895 bytes)


(If you are matching a properly-cropped stereo pair, you don't need to make any selection.)

3.    Activate the image containing the colors that you want to transfer (for example, the left-hand images above).

4.    Open Metrix, which is in the "PSI" submenu of your filter menu.

5.    Click "Analyze," then click "OK." You will not see any color changes at this point because Metrix is simply extracting color information from the image.

6.    Then, activate the other image.  Open Metrix again, but this time, click "Apply" and "OK." This will cause the color distribution of the first image to be applied to the second image.
