== Aperture ==

Math for the aperture has been tried. For the third iteration, an aperture can be calculated by finding the magnification of an image at the location of the aperture, and if it is larger than the aperture allows, the amount of image remaining can be calculated by simple ratio.

The above equations can generate images magnified or offset beyond what the camera can resolve, as the camera lens assembly has a radius of 3.75 cm. To compensate for this and prevent resolution of an image larger than the camera can allow, we need to superimpose over our final offset and magnified image the effects of the lens assembly. At any given lens, the image will be at either its maximum or minimum magnification counting from the previous lens. These lenses can be generated by the equation

An aperture would be more difficult to add for the fourth iteration, but it should be possible.

An aperture for the fourth iteration is being calculated and will be posted alongside the fourth iteration.

 

where O is the O-coordinate for the given lens, <math>O_c</math> is the O-coordinate for the center of the image circle at this lens, and M is the magnification of the image at the given lens.

 

These coordinates are used to set the center of the lens superpositions. With this known, and with the image magnifications known, we can draw the lens superpositions and observe what of the image is cut off by the lenses.
