Have it as a giveaway from 12/2022. The way FOCUS projects 4 Pro is generally used is with Macro photography, usually with the camera mounted to a manual or motorized track -- P/Shop has something similar but it's not such a dedicated tool. The way it works is you focus on the closest point of your subject, take a shot, then move the camera a tiny amount closer to the subject, and without refocusing take another shot & so on. What you're doing is essentially taking perfectly focused photos of slices of the image, which will be stacked, sort of reassembled in the software. Pros who specialize in this method often have a motorized, automated track that moves the camera forward, takes the shot, & repeats this maybe dozens of times.
To take Macro photos, which are extreme / magnified closeups, you generally want a camera with interchangeable lenses. You can buy magnifying adapters that attach to removable or fixed lenses that will work, but with less quality than a dedicated Macro lens -- the quality of the shots with one of these adapters varies with the make/model & usually price paid. You can also use extension tubes that mount between the camera & lens, & adapters to reverse the lens, mounting it backwards on the camera. eBay is a good place to look for the interchangeable parts to built a track setup that will mount to a tripod -- you'll find different lengths of standardized diameter tubes, adapters to mount those to a tripod mount, geared sliding camera mounts that mount onto 2 parallel tubes that themselves can slide back & forth on those tubes etc. The automated setups are AFAIK usually DIY projects using Arduino.
Macro photography is a bit of a niche... most photographers at all levels tend to specialize, whether it's a fashion photographer who only shoots fashion or an amateur who just enjoys shooting certain types of photos more than others. However, there's a comparatively limited market for macro photos, so far fewer pros specialize in that genre -- your work might be featured in books or magazines targeting macro photographers, it might appear in scientific journals, but far more people will hang a landscape on their wall than an extreme closeup of a flower or insect. So why bother? The best answer I can offer is remembering the excitement I felt as a young child when my parents gave me a microscope. Extremely close up, it's a different world than the one we see every day with our naked eyes. And you kinda have to really like [maybe love] it because macro photography arguably takes more work & specialized tools than most other specialties. You can use a zoom lens for all sorts of photos, but a macro lens, not so much.
From the comments on the download page: What about FOCUS projects 4 Pro just for sharpening a single photo? Very Probably not... in a bit of an aside, sharpening photos in software is Very iffy. You can apply a small amount using your image editor's builtin tools or a high pass filter, but you have to be careful because there can often be unintended consequences. AI tools, like those in P/Shop, or from companies like Topaz & Luminar can sometimes work wonders, but the odds of those unintended consequences skyrocket. When / if I use them, I always use a mask to block the effects in places where it distorts the photo by emphasizing & amplifying shadows & noise. That's because if you actually need to sharpen a photo, it already has too much noise, & that noise will throw off the sharpening algorithms that look for object edges. The result is you get object edges & shadows where there shouldn't be any, like on faces, or striped clothing, or it may create gradient blobs on the background and so on. Strands of hair can become very pixelated, and where several edges come close to each other, it can turn into an unrecognizable mess.
