This instructable will tell you how to get up close and personal, with a smartphone/tablet with a good camera , and an old cd or dvd player.
There are a few example shots in this instructable, but I only have an ipod touch 4g, which only has a vga quality camera, so I cannot record hd pics like you might with an iphone. (UPDATE: now I have a smartphone with a 8mp camera, so the last few photos are better quality)
Also, please forgive me, I don't actually have any pictures on how to take apart dvd players and things.

Step 1: Step 1, take it apart.
Once you manage to get that out, carefully wedge the focusing lens out of the module
