Change the type of template or preset you want to use by selecting from one of the 6 categories in the Photoshop New Document window (5 categories in Illustrator). In the example above, I've selected the Photo category in Photoshop.
Click once on a template to see additional a description and additional details about the template on the right-side of the window. Templates can be li licensed for free from Adobe Stock, or for a small fee, depending on the template creator's preference. Free or not, you will still be prompted to license the template for use. If you like the template, choose Download. At this point, you will be prompted to license the template.
Downloaded templates are added to a Creative Cloud library called Stock Templates. You can access this library in the Libraries panel.
Once the template downloads, you can click the Open button in the New Document window to launch the file.
Note: If you download a free template created by Adobe Stock, the file also includes instructions on how to customize the document with your own content. In this Adobe Stock Illustrator template, you can learn how to create presentation graphics. Note: templates created by other designers may not include any instructions for use.
In the Vintage Photo Effects template (created by Collective Offset), I can quickly create an original antique looking photograph, without needing to know how to create clipping or bitmap masks. To add my photo, I begin by double-clicking on the thumbnail image in the layer named [YOUR PHOTO HERE].
This opens an empty smart object document where I can copy and paste my own image into the layer.
Once I have pasted and positioned my photo, I save the smart object file and close it.
My template document now contains an image of my choosing or creation. Save the file as a new .psd file, or use the Export options to export the file as a jpg, gif or PNG file. I can easily change the image by double clicking the Smart Object layer again and pasting in a new photo.
