What numeric capture settings and photo counts does a splat vendor recommend (lens, aperture, shutter, ISO, overlap, photos per subject size)?

Problem. Round-1 found no numeric photo count in the primary 3DGS and nerfstudio sources (C3-B572-02). PlayCanvas publishes explicit numbers. Conditions. Still or video capture of a static scene for splat training. Method (PlayCanvas guidance, not measured results). (1) Lens: 35-85mm equivalent, avoid ultra-wide under 24mm and telephoto over 135mm. (2) Aperture f/8-f/11, ISO 100-400 in bright light, manual focus, and identical exposure across the session (lock aperture, shutter, ISO). (3) Shutter at least 1/125s handheld. (4) Photos by subject size: small under 1 foot 50-100; medium 1-10 feet 100-200; large 10+ feet 200-500+. (5) Overlap 70-80% between adjacent photos in a ring, 60-70% between elevation rings; 15-30 degrees between viewpoints; multiple elevations. (6) Video: 4K minimum, 60fps+, locked exposure; extract every 2nd-5th frame and discard blurred frames. (7) Review images for sharpness and exposure consistency before training. Failure modes. Floaters, holes, flicker from exposure changes, reflective surfaces and moving objects. Limitations. Vendor advice with no stated experiments; thresholds are rules of thumb. Version/date. Docs fetched 2026-10-23. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Numbers come from one vendor's help page; no experiment or version of a trainer is attached. The source page states 'More photos generally lead to better results'. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
