Have you heard of the swing chart? They are made by using multiple lenses to take multiple photos at once, and the resulting stitched together’gram is a gif version of a three-dimensional image. It looks 3D, and it—well, it swings. Those with a boomerang effect (that is, good circulation) are particularly precious.
Wigglegrams are usually produced with Nishika quadruple lens cameras. In order to meet the growing demand, the prices of these cameras will naturally increase. Nishikas has four lenses and creates four independent half-frame images by dividing four photos into two frames of film. In contrast, [Joshua]DIY eyes use the three plastic lenses of a disposable film camera to put three images on one frame of film.
The only real disadvantage is that the camera must be close to the subject, because the three lenses are tightly packed. Another disadvantage is that there is no viewfinder when using this lens. There must be partition walls between the three lenses to keep the images separated, and these walls must extend all the way into the camera body.Canon A-1’s viewfinder does not allow this, so [Joshua] Push it away.
[Joshua]The initial design method to find the ideal lens distance to the film plane was to perform a lot of calculations, but he eventually got Goldilocks-ing and iterated many times until it was just right. If you have Canon SLR and want to build one of them, As far as STL is concerned, you are lucky.
What else can a bunch of old disposable cameras do? Of course, build your own flash memory.
