History Reframed - Custom Photoshop Art Mockups and Generative Fill Frames

Hello! My name is Austin. I'm based in Houston, TX. This year I am starting up an ecommerce business through which we'll be selling collected works of vintage art, prints, photography, antiques, etc. All products are curated from around the world, so not print on demand or customer submitted. The other component of the product is customers will be able to customize the framing and matting options per piece. To present the products online, I'd like to use photoshop mockup files for initial product images, and then use shopify preview apps to showcase the customization options. What this will require is a base photoshop mockup file for each frame size/ratio offered, and then transparent files of each offered frame material to be connected to swatches inside the store (that way every single art work doesnt need a mockup image of every conceivable combination of frame and mat). The transparent image frame options will then overlay the initial mockup file. There are plenty of artowrk mockups available on things like etsy, but I would like to go the custom route to cover all aspect ratios I will sell, and have a uniform aesthetic across all. The framing materials will be sourced locally wholesale, which the distributor has hi res photos of each type already available. A component of the job will be to "generate" full frames from corner sample photos. I will attach an example psd file of the mockup style and functionality Im going for, as well as a sample corner photo to see if it's sufficient material from which to generate full frames. -Austin
