A person may not knowingly possess and intentionally retain a film, videotape, photograph, or other visual representation showing an actual child or a computer–generated image that is indistinguishable from an actual and identifiable child under the age of 16 years: engaged as a subject of sadomasochistic abuse; engaged in sexual conduct; or in a state of sexual excitement.

A person who violates this section, having previously been convicted under this section, is guilty of a felony and on conviction is subject to imprisonment not exceeding 10 years or a fine not exceeding $10,000 or both. Nothing in this section may be construed to prohibit a parent from possessing visual representations of the parent’s own child in the nude unless the visual representations show the child engaged: as a subject of sadomasochistic abuse; or in sexual conduct and in a state of sexual excitement. It is an affirmative defense to a charge of violating this section that the person promptly and in good faith: took reasonable steps to destroy each visual representation; or reported the matter to a law enforcement agency.
