Appellant, Frederick W. Hunter, was convicted of sexual exploitation of a minor after he photographed his partially-clothed, adopted daughter in provocative poses. See Iowa Code §§ 728.12(1), 728.1(6)(g) (1993). On appeal, he claims section 728.1(6)(g) is void for vagueness. We disagree and affirm.
I. Background Facts and Proceedings.
Clad only in his underwear and sexually aroused, Hunter photographed his twelve-year-old daughter in various stages of undress in a motel room. Several photographs show the girl’s exposed breasts, pubic area and buttocks. In a number of the photographs, the girl is in provocative poses: legs widely parted; hands draped on her breasts; a pillow between her thighs; and hands cupping her buttocks. When Hunter attempted to have the film developed, the processor summoned the authorities.
The State charged Hunter with sexual exploitation of a minor in violation of sections 728.12(1) and 728.1(6)(g). Hunter filed a motion to dismiss contending section 728.1(6)(g) was void for vagueness because it did not contain a definition of the term “nudity” or of the phrase “for the purpose of arousing or satisfying the sexual desires.” The district court overruled his motion. Hunter then pleaded guilty and was sentenced to prison for a period not to exceed ten years. Hunter appealed. 1
II. Standard of Review.
We review constitutional claims de novo.
State v. Huisman,
III. Vagueness Claim.
Iowa Code section 728.12 prohibits the sexual exploitation of a minor:
A person commits a class “C” felony when the person employs, uses, persuades, induces, entices, coerces, knowingly permits, or otherwise causes a minor to engage in a *463 prohibited sexual act or in the simulation of a prohibited sexual act if the person knows, has reason to know, or intends that the act or simulated act may be photographed, filmed, or otherwise preserved in a negative, slide, book, magazine, or other print or visual medium....
Iowa Code § 728.12(1) (1993) (emphasis added). The “prohibited sexual act” providing the basis for the charge against Hunter is “[n]udity of a minor for the purpose of arousing or satisfying the sexual desires of a person who may view a depiction of the nude minor.” See id. § 728.1(6)(g).
Hunter claims the definition of “prohibited sexual act” is unconstitutionally vague. First, he argues there is no statutory definition of “nudity of a minor for the purpose of arousing or satisfying the sexual desires of a person.” Second, he claims First Amendment rights are implicated because the statute reaches persons who merely derive sexual enjoyment from a photograph of a nude minor.
A.
Vagueness jurisprudence.
“As generally stated, the void-for-vagueness doctrine requires that a penal statute define the criminal offense with sufficient definiteness that ordinary people can understand what conduct is prohibited and in a manner that does not encourage arbitrary and discriminatory enforcement.”
Kolender v. Lawson,
First, because we assume that man is free to steer between lawful and unlawful conduct, we insist that laws give the person of ordinary intelligence a reasonable opportunity to know what is prohibited, so that he may act accordingly. Vague laws may trap the innocent by not providing fair warning. Second, if arbitrary and discriminatory enforcement is to be prevented, laws must provide explicit standards for those who apply them. A vague law im-permissibly delegates basic policy matters to policemen, judges, and juries for resolution on an ad hoc and subjective basis, with the attendant dangers of arbitrary and discriminatory application. Third, but related, where a vague statute “abut[s] upon sensitive areas of basic First Amendment freedoms,” it “operates to inhibit the exercise of [those] freedoms.” Uncertain meanings inevitably lead citizens to “steer far wider of the unlawful zone ... than if the boundaries of the forbidden areas were clearly marked.”
Grayned v. City of Rockford,
B.
Standing.
A defendant charged with the violation of a statute has standing to claim the statute is unconstitutionally vague as applied to him or her. A defendant does not necessarily have standing to claim, in addition, that a statute is unconstitutional as applied to others.
State v. Price,
If a statute is constitutional as applied to the defendant, the defendant lacks standing to make a facial challenge unless a recognized exception applies.
Id.
One such exception is a situation in which First Amendment rights are implicated.
Id.; see Chapman v. United States,
The United States Supreme Court has not been entirely clear with respect to the scope of this First Amendment exception. In
Parker v. Levy,
that one who has received fair warning of the criminality of his own conduct from the statute in question is nonetheless entitled to attack it because the language would not give similar fair warning with respect to other conduct which might be within its broad and literal ambit. One to whose *464 conduct a statute clearly applies may not successfully challenge it for vagueness.
Parker,
In
Kolender v. Lawson,
the Court provided further illumination upon the question of standing.
See Kolender,
The Court noted that in the arbitrary enforcement context, facial vagueness is “logically related and similar” to the overbreadth doctrine.
2
Id.
at 359 n. 8,
"When speech or expressive activity forms a significant part of a law’s target, the law is subject to facial challenge and invalidation if: (i) it is “substantially overbroad”— that is, if its illegitimate applications are too numerous “judged in relation to the statute’s plainly legitimate sweep,” and (ii) no constitutionally adequate narrowing construction suggests itself.
Overbreadth,
Because
Kolender
represents the most recent statement of the Court’s position, we apply the more liberal standing test of
Ko-lender
and
Young.
Under this overbreadth-type approach, a facial challenge is permitted if a statute reaches “a substantial amount” of protected conduct.
See Broadrick v. Oklahoma,
*465 Our analysis begins, therefore, with an examination of whether section 728.1(6)(g) is vague as applied to Hunter. If the statute clearly applies to Hunter’s conduct, we will then consider whether the statute, nevertheless, reaches a substantial amount of protected expression. If it does, we will address Hunter’s facial challenge to the statute. If the statute does not reach a substantial amount of protected conduct, we will not decide whether the statute is void for vagueness on its face.
C.
Vague as applied.
Although we are at this point considering only Hunter’s vague-as-applied claim, we must still examine the statute “on its face.”
See Price,
Hunter complains there is no statutory definition of “nudity” or “for the purpose of arousing or satisfying the sexual desires of a person” so as to alert him his conduct was prohibited. We do not think the challenged language is vague as applied to the situation before us.
A statutory term provides fair warning if the meaning of the word “is to be fairly ascertainable by reference to similar statutes, prior judicial determinations, reference to the dictionary, or if the questioned words have a common and generally accepted meaning.”
State v. Kueny,
Whatever doubts there may be about the applicability of the statute in other contexts, Hunter’s conduct falls squarely within the statute’s target of “nudity of a minor.” Although Hunter’s daughter is not totally naked in any photograph, various photographs do show her bare breasts, pubic area and buttocks. Therefore, the statute’s nudity requirement is not vague when applied to the conduct charged to Hunter.
Nor is the statute vague in its application to Hunter of the phrase “for the purpose of arousing or satisfying the sexual desires.” A similar challenge was made in
State v. Bohannon,
The same analysis is appropriate here: the challenged phrase allows the general public and those enforcing the statute to distinguish between prohibited conduct and protected expression.
See Village of Hoffman Estates v. Flipside, Hoffman Estates, Inc.,
455 U.S.

489, 499,
D. Facial vagueness. Having concluded the statute clearly applies to Hunter’s conduct, we must now decide if Hunter has standing to make a facial vagueness challenge. He argues the statute unconstitutionally impacts First Amendment rights because it does not require anything more than nudity of a minor. The conclusion to be drawn from Hunter’s characterization of the statute is that it reaches a substantial amount of protected expression. We disagree.
The prohibition at issue here was added in 1978 “to prohibit the production of sexually explicit material whose subject is, in whole or in part, a child or children.” 4 John L. Yeager & Ronald L. Carlson,
Iowa Practice: Criminal Law & Procedure
§ 641, at 160 (1979). States have a compelling interest in the regulation of pornographic depictions of children.
Ferber,
When considered in this context, we conclude section 728.1(6)(g) does not reach a substantial amount of protected expression. Contrary to Hunter’s contention, the statute does not criminalize the mere nudity of a minor; section 728.1(6)(g) requires an element of scienter, “for the purpose of arousing or satisfying the sexual desires of a person who may view a depiction of the nude minor.” See Iowa Code § 728.1(6)(g) (1993).
Hunter has not identified examples of legitimate expression that may be repressed by this statute, nor do we speculate on what form such expressive conduct might take. In the overwhelming majority of cases the distinction between child pornography and artistic expression will be clear. Therefore, we conclude any questionable cases falling on the borderline between child pornography and artistic expression would be few.
For these reasons, this case is inappropriate for the adjudication of the hypothetical claims of persons not before us. The potential infringement on protected expression is too insubstantial to give Hunter standing to claim the statute is unconstitutionally vague on its face.
See Young,
IV. Summary.
Iowa Code section 728.1(6)(g) is not unconstitutionally vague as applied to Hunter. His conduct clearly fell within the statute’s prohibition of photographing a nude minor for the purpose of arousing or satisfying the sexual desires of a person viewing the pictures. Because the statute does not encompass a substantial amount of protected expression, we do not consider Hunter’s facial vagueness challenge. We affirm Hunter’s conviction and sentence for sexual exploitation of a minor.
AFFIRMED.
Notes
. Hunter’s guilty plea did not waive his right to challenge on appeal the statute under which he was charged as unconstitutionally vague.
See State v. White,
. An overbroad statute reaches protected as well as unprotected conduct.
See State v. Farrell,
. The defendant in Bohannon took photographs of his nude, sixteen-year-old stepdaughter.
