Thanks for the feedback, Alex.
Yes that would be great, if all data would be available for an easy use.
I have placed the values I got from the Epson site as accurately as possible, and so far, I can tell they match. But please check with the projector if these numbers match. The remote control has different vertical adjustments than the Specification tells. Please check them with the projector. There are conflicting numbers with the shift angles.
With a zoom factor of 1.0, I would say that the used area of the projector chip is 19.7mm x 34.9mm, whereby the 3chip indicates that a prism is among all three, which might change the size, but mathematically that should be the size at Focal length 18.2 (Zoom 1.0).
I can see that this would be useful for this kind of work. The Problem that showed up with this projector was that it had no LCD-“slide” size given (a sensor’s equivalence). It is sometimes difficult to get. Even for video cameras, when the sensor is set as a 1/2 inch chip, which was in the old days the enclosing glass tube, not the size of the “chip”.) So it is kind of the stopper in the idea.
If these values were available for all projectors, it would be easy to set things in math. The simplest way to get the data is to take the focal length times 100 and measure the image width at that distance. This value divided by 100 should give you the “sensor-size”.
In fact, you can check with the Cinema 4D camera if the results are true.
Focal length 18.2, sensor 34.9
The shift of +/-30º is close to ~50% shift in the camera. (+/-44%v and +/-52%h).
Enjoy your project.
