Iodine fuming is recommended for developing latent fingerprints on absorbent surfaces such as unpainted wood, paper, cardboard, or other porous surfaces. When iodine crystals are heated, the sublimation process produces iodine gas, which reacts with the oils and fatty acids in the sweat of fingerprints to produce a visible brown color. This technique is non-destructive and relatively easy to perform in the field.
