Check that the coverage circle is large enough to cover the negative. Short flange distances ( mirrorless cameras) give you longer focal lengths and brighter images although they are still dark. The geometry related to the mapping of a pinhole camera is illustrated in the figure. In the pinhole camera model there is only one focal length which is between the principal point and the camera center.

Find your focal length and pinhole size. A camera with a 100 mm focal length will produce an image circle with a diameter of 350 mm. Enter the film dimension and press calculate for the angle of view, 40 is normal, 50 wide angle. Using extension tubes will give you wider focal lengths. When i was in school we all.

Because the camera has square pixels and a zero skew factor, we can reduce the camera to the simple pinhole camera model to obtain the following relationship between (x (l,k),z (l,k)) and u (l,k),l = i,j: Focal length) from distortion (aspect ratio). Its itersection with the image plane is referred to as the. It affects the size of the projected.

The distance from the sensor to the pinhole determines the focal length of the lens, so it makes sense that if you want a longer focal length pinhole lens, you need to add to the distance between the sensor/film and the pinhole. Such a parameterization nicely separates the camera geometry (i.e. Using extension tubes will give you wider focal lengths..

This is an example of my scene from two different views: If you have a 10cm object at 10m from the camera, and you want that to be 0.5mm (50px width), you need to place the sensor 0.5mm*10m/10cm=5cm behind the pinhole. Find your focal.
