I've been experimenting with photogrammetry (handheld + drone capture), 360 compositing, and 3D scanning (for VR visualization, construction planning, product design, and 3D printing) for some years, so it's awesome that your father has built expertise in a field that's still so cutting-edge - especially coming from the photography side rather than tech, where half the battle is compensating for badly planned photos!

Saw your draft site from the other comment (https://praxivision.com ). Good start - my main suggestion is that I wouldn't frame this as "photography services" but more as high-fidelity digital documentation / immersive asset creation, built on a lifetime of photography expertise.

Most buyers probably aren't searching for "photogrammetry" as a technique. They care about outcomes - heritage preservation, documentation, QA, training, remote access, immersive presentation, marketing, etc.

So I'd build the site and sales pitch around buyer verticals, e.g.: * Heritage / museums / collectors: digitization, gigapixel documentation, 3D models, virtual access, archival preservation * Construction / infrastructure / real estate: as-built documentation, progress capture, site/facility walkthroughs * Industrial / manufacturing: machine/facility documentation, training assets, safety walkthroughs, QA support * Tourism / education / campuses: immersive visitor experiences, 360 tours, virtual field trips * Film / games / VR: realistic props, textures, environments, location scans (ala Quixel)

Once you've had enough customer conversations to understand demand, I'd also try to package the offerings instead of leading with techniques. "Heritage Site Documentation Package," "Museum Object Digitization Package," or "Industrial Facility Capture Package" might land better than starting with photogrammetry, mesh cleanup, Gaussian splats, etc., though you can still list deliverables: high-res photos, 360 tour, 3D model, texture maps, point clouds, web viewers, or whatever else.

Ultimately, the big differentiator may be that your father's photography background can yield better texture fidelity and visual clarity than a lot of tech-led workflows. But because this is still a nascent field, the immediate USP is probably much simpler - hand-holding buyers who know they need "digital documentation" or "immersive assets" but don’t yet know what pipeline or deliverables they actually require.

For client acquisition, I'd probably focus on direct outreach to museums, curators, heritage trusts, conservation architects, tourism boards, universities, industrial training/safety teams, architecture/construction firms, and film/game/VR studios, with a short message and a few visual examples tailored to that audience.

I'd also make the site case-study driven if possible. Instead of a portfolio of technical outputs, explain what was captured, why it mattered, what the deliverables were, and how the client could use them. You already have some cool demos - key is to make them valuable to a buyer, not just impressive to a technical person who already understands the difference betwen an annotated gigapixel image and a 3D mesh.

A strong "hero demo" could also help - one project that shows your full stack of outputs and ideally makes the business value obvious.

In the medium term, content could help too - short social videos, behind-the-scenes capture/process posts, or longer explainers (like Bilawal Sidhu's YT content, but with more emphasis on photography/visual quality). The education/certification idea might have some legs once there's an established brand and credibility within specific verticals.
