Lesson 2

Fingerprinting

Iodine Fuming Method

Processing...
The product! (It is quite faint though.)

Cyanoacrylate (Superglue) Fuming Method

The first try, which turned out blurred because Chin Ying and I unthinkingly went to plaster the strip against the science lab door while trying to rub it down with ethanol!
Much clearer this time! The top two are my right thumb and index finger respectively. The big fat blob at the bottom belongs to Chin Ying.




Ridges and Pores Activity (using white glue to make an impression of the fingerprint)


Both pictures are impressions of my left thumb. Taken with my phone's camera! I had a hard time adjusting the angle of my phone so that it can "see" down the microscope. About the coolest thing I have seen thus far...



Powder Dusting Method

Powder dusting really takes a bit of skill. My right thumb, positioned on the left. It is quite okay-done, except for an odd little air bubble at the side.
