Physical Camera Usage

[Reaversword]

What means the warning: Rendering is not re-entrant?

When we work with the physical camera at extremely short shots, like little diamons in a jewel, is not difficult get the inverted render or the light diminishes till completely black.

This is because so close than the camera lens can't invert the image? or when it turns black, is because we have the point in which image inverts in the ccd?

For other side, working at this details level, sometimes, at dolly-out, physical cameras does strange movements of re-close to the object, right?


For working with this kind of stuff, we might set the physical camera like in Macro mode?. How?.
It is possible to configure the physical camera like a microscope or a telescope?

Build a glass lens in 3D and place it in front of your camera. I bet you could do a tilt shift too.

Most Macro lenses are like around 100mm with extremely short focus ranges, can't you do the same for "Macro Mode" as it's just Focal length + focus distance?

One thing I think the V-Ray physical camera would be cool (for lazy buggers like myself) is an evaluative exposure mode instead of the current pure manual mode! Haha

Humm, I need do some tests using "lenses" and camera parameters and focal lenght activated. Appears unimportant the fact of focus distance, but increases incredibly the sensation of little little world. All appears a mock up. Then, get the same sensation, but with a perfect in focus with a little jewel... I need to keep trying.
