its only possible on mobile cam
Step 1 : teardown an old cd/dvd drive. There will be a moving head on a rail. the head has a tiny lens outside, a relatively larger lens inside, and a prism like thingy. the larger lense within the head, usually protected by glued on screws, is needed. The drive will prolly not be usable after this point.
Step 2 : stick it onto your phone cam. Used card and sellotape once, safety pins and rubberband the secnd time (easy to make quick adjustments). feel free to rig up something.
Step 3 : take photos. no subject you can see with naked eye is too small.
