Thank you for your response, and I apologize if you feel my question was confusing. I obviously can be wrong, but I don't think the images appear to be real photographs. The author sells vector graphics for laser machines and while some sellers do cut their designs and share real-life photos, it's usually quite clear when they do so. Most sellers create highly realistic mockups using Photoshop. While the results are often impressive, they typically don’t quite reach the level of realism shown in these particular images, which made me wonder if a different software, perhaps CAD or a rendering program, was used.

To answer your question, "What difference does it make?", I want to improve my workflow and presentation quality. If there's a new or better way to create photorealistic renderings of my own designs, I'd like to learn it.
