Set on Fire

In any situation it is about compromise.
- There is the basic rule of thumb with the "standard specification" of 1/30.
"The 1/30 Rule refers to that the Stereo Base or separation between lenses (from center to center) should be no more than 1/30 the distance of the NEAREST object to the camera lenses." This is good for life-size objects viewed on medium to large screens (3D TVs to cinema screens).
- For normal size PC monitors a larger stereo base will increase the perceived depth.
- For same stereo base, the larger the 3D picture will increase the depth.
- For small things, a larger than 1/30 stereo base is recommended (1/25-1/15).
- For macro work, even larger stereo base is recommended (1/15-1/10).

So, your picture with "my specs" (1/12) is very deep and have a window violation. Without window violation, it have "out of normal depth" and can be viewed comfortable on a 3D screen up to 49"/125cm wide. At ~49" wide, the depth will be from the screen plane to infinity.
With screen violation can be viewed on any screen size, but not comfortable and not by everyone (because the subject have a limited depth in reality).

My image can be viewed on screens up to ~100"/250cm wide as it is (without window violation), because it have a small depth and no background. To be properly seen on my 134"/340cm wide projector screen, will need to accept some window violation for the crystal at the base.

So, my "specs" for close-up/macro shots are not good for life sized 3D subjects.
Starting some time ago, I prepare my 3D pictures to be viewed on VR devices, which are equivalent to medium/large screens, so on small screens can be perceived as to have no great depth.🙂
