Inside an old hay/straw barn. 3D Photogrammetry

Nice work! I really like the specks of dust floating around.

Regarding tripods, handheld photogrammetry is so much faster, but for poorer lighting a really solid tripod becomes a necessity. The Valve Lobby scan was all done on a tripod - this meant I could go down to ISO 100 at f/11 for maximum sharpness, resulting in ~2 second exposures. The Lava Tube scan was something similar.

I've just posted a tutorial on lighting setup for photogrammetry environments in SteamVR Home:

It's aimed more towards outdoors stuff, but most of it should also apply to indoors as well. Lighting for dynamic objects is a little more complex than in Destinations, but it's a lot more powerful for completely artificial scenes. (Documentation on that coming sooner or later...)

Thanks for the positive ratings and favs!
It's been quite a job to get this done.

So when I realized you guys like this type of photogrammetry, I went back into the barn and planned to create an even bigger room.

This barn is actually much bigger but it's not that bright in there. It requires good timing to have the sunlight pointing at the right direction. I have taken another row of photos, however when I went back on my PC, I realized that most of the 440 photos are blurred because of movement. It looked alright on the little camera display... I've had the tripod carrying in my hands, put one foot of the tripod in the pocket of my pants, another stuck on my belt and thought it would be steady.
No it was not.... I must have looked like an idiot with the tripod "wearing" in a barn. :D
Perhaps my camera sucks, I wish they weren't so expensive.

It requires a lot of discipline to take photos in there. Especially since it's hot, dusty and smelly.
