My frist ever attempt at Photogrammetry.
A 1938 Leica IIIa
I really did just about everything wrong (losts of glass and reflective surfaces, extremely quick-and-dirty photoshoot, not enough good high-angle shots for texturing) and still got a shockingly usable result... with about 2 million triangles! So I decimated it like crazy, down to about 200k (still obscenely large) and it looks... surprisingly good.
