Re: hands-on object VR

Lighting objects is already difficult, and moreso when you physically turn your object on its side but shoot it from the same position. Your shadows are "wrong" if you rotate the image back to the intended view.

Yep. The consequence is that the lights need to rotate with the object when I move it to then rotate the image back to the intended view. The question is how much tolerance there is when doing that.


yeah, my ambition is true, full multi-row object.

36 * 36 images (for example)? Yikes! Is this for a client or for kicks?

YEP. Discussed it with the client, He is aware of the envelope being pushed and is open discussing paying for the performance.


Maybe nix the turntable, and go for just the tripod stem or post that it's on. Or suspend your object. Or (possibly easiest) turn your object on its head.

Most objects don't really require 36x36 views, but the one that attracted my attention for this does. It has a pretty complex shape from all sides. When left to gravity on a table it takes the "wrong" orientation (since there are no visual references, the best reference is to keep it oriented as if the body is standing upright), so even for a simple single row VR there is the challenge of holding it in place.

Should do a single row VR of it tomorrow. the solution for holding it in place is Play-Doh modeling clay. A color that contrasts enough with the rest of the object so to be easily removed in post-processing if necessary. Two or three support structures that can be removed/added when they come in / leave the field of view.

But again, this is for single row and won't be of much use for multi-row, I am afraid.


In your example, the lighting is pretty dramatic. If you don't need the drama, maybe go a little flat (more even) with the lighting -- this will help some.

the drama is intended. the first objective with this object (pun intended) was to grab attention. it is designed to show what can be done and to attract the necessary financial resources. Before seeing this, the client was not inclined to listen to expensive ideas about multi-row panoramas. One shown this, he started to ask questions, even to the point of thinking whether it makes sense for his organization to buy the 20.000$ Kaidan rig (no, it does not make sense).

it's like the plastinates themselves. the objects on display are colorized. liquid colored latex is injected during the plastination process. uncolorized plastinated originals are pretty dull (I'll do one of them tomorrow too, to see if light can do a difference).


It's all tradeoffs! :)

yes it is! and I might not have time this year to shoot http://www.photopla.net/060708festeteq
