Step 6: Mounting the lens (more permanently)
Next slide the fastener through the lens and case hole and spread the paper fastener's wings so they curl into the case. Put a piece of transparent tape over it to discourage scratching the iPhone (you could use something industrial but I wanted to keep up the clear case effect). Now just slide the lens over the camera whenever you want to use the macro!
I'd like to have mounted the lens inside the case and cut some of it away, but I thought I'd quit while I was ahead.
Also note that the app SnapTell (AppStore link) is pretty fantastic-- it basically bypasses barcodes and does image recognition on pictures you take of objects. Basically a Shazam for products. Right now it's only for CDs, DVDs, and games, but can you imagine what either of these technologies could do for grocery shopping!?
