Under federal law (18 U.S.C. §2256), child pornography1 is defined as any visual depiction, including any photograph, film, video, picture, or computer or computer-generated image or picture, whether made or produced by electronic, mechanical, or other means, of sexually explicit conduct, where
the production of the visual depiction involves the use of a minor engaging in sexually explicit conduct; or
the visual depiction is a digital image, computer image, or computer-generated image that is, or is indistinguishable from, that of a minor engaging in sexually explicit conduct; or
the visual depiction has been created, adapted, or modified to appear that an identifiable minor is engaging in sexually explicit conduct.
Federal law (18 U.S.C. §1466A) also criminalizes knowingly producing, distributing, receiving, or possessing with intent to distribute, a visual depiction of any kind, including a drawing, cartoon, sculpture or painting, that
depicts a minor engaging in sexually explicit conduct and is obscene, or
depicts an image that is, or appears to be, of a minor engaging in graphic bestiality, sadistic or masochistic abuse, or sexual intercourse, including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex and such depiction lacks serious literary, artistic, political, or scientific value.
Sexually explicit conduct is defined under federal law (18 U.S.C. §2256) as actual or simulated sexual intercourse (including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex), bestiality, masturbation, sadistic or masochistic abuse, or lascivious exhibition of the genitals or pubic area of any person.
