CSI Fingerprinting Answers to Questions:
Ridges and Pores Activity
Q)Where are the pores found? Are they regularly spaced?
A)They are found on the ridges of fingerprints. Yes, they are regularly spaced.

Cyanoacrylate(Superglue) Fuming Method
Q)If the contrast of the white against the black background is still too faint for a good detailed photograph to be captured, what could be done to enhance the fingerprint?
A)Dye the fingerprint with fuorescent substance to make it glow in UV light.

Iodine Fuming Method
Q)What are the possible substances that may be used to render the prints more permanent?
A)

Powder Dusting Method
Q)What is the magnetic powder dusting and how does it work?
