The panel is called "Adobe Paper Textures Pro" by Russell Brown. It lets you choose from an array of textures and add them to your Photoshop document. The panel will scale the texture so that it fits the document dimensions. You can add more than one textures. Each texture is actually an individual layer.
The CC version is available for download on the Adobe Add-ons site, on this page: https://creative.adobe.com/addons/products/791 while the CS6 version is available here: https://creative.adobe.com/addons/products/791
Download and install it using the Extension Manager for your PS version. To load the panel in your work area select Window > Extensions > Adobe Paper Texture Pro from the menu.
The action creates a gray background by default, which you can replace with your own.
With the "background" layer selected, I clicked on the panel icon (it looks like a blue bee or something):
The panel shows up. At the top you can set the blending mode of the new texture layer that will be created. Below you can see the available textures. Hover your mouse over the icons to view their names. Double click on any of them to add it to your document.
It took me just a few seconds to create this beautiful background:
Let's move on to the second example.
At first I used my "Retro" effects to turn a color photo into a vintage item. Then I used the panel to create a beautiful retro background:
Here's how I created the texture:
I selected the "background" layer.
I set the panel's default blending mode to Normal and I double clicked on the "2014_Ezekiel_Plum" texture.
I set the panel's default blending mode to Multiply and I added the "2014_Verdigris_Scratch" texture. I lowered the layer's opacity to 60%
I set the panel's default blending mode to Soft Light and I added the "Colosseum_Sienna" texture.
I added an "Exposure" adjustment layer; I set Exposure, Offset, and Gamma Correction to: 0.00, +0.04, and 1.00 respectively.
I added a "Hue/Saturation" adjustment layer; I activated the "Colorize" option and set Hue, Saturation, and Lightness to: 25, 30, and 0 respectively.
You can combine the various textures to create impressive backgrounds. Change the opacity and the blending modes of the individual texture layers to create a unique blend; Use a couple of adjustment layers. And if you come up with an impressive texture, don't forget to save the Photoshop document, so that you can review the settings and apply them to another photo.
