Alan Ray Steen appeals his jury conviction for one count of production of child pornography for video he surreptitiously recorded in a tanning salon, while the subject of the video was unaware of the filming. Steen was sentenced to the statutory minimum of fifteen years in a federal correctional facility. As we will explain, Steen did not violate the statute he was charged with offending. We therefore REVERSE Steen’s conviction.
I.
Steen frequented the Electric Sun Tanning Salon in Odessa, Texas, where an employee would assign him to a room for his tanning session. Because of the heat generated by the equipment, the salon’s walls did not reach the ceiling between tanning rooms. When standing on a chair, Steen could not see over the walls but was able to hold a camera on top of the wall partition and film activity in the rooms adjacent to him.1 On April 3, 2009, Steen filmed C.B., who began tanning next door. The video displayed C.B. for about fifteen seconds as she adjusted the machine settings and entered the tanning bed. Most of the video displayed her back and hair, though her pubic region was visible on the right edge of the frame for approximately 1.5 seconds before she closed the tanning bed.2
On April 13, 2009, Steen returned to the salon and entered a tanning room to which he was not assigned. Steen began filming an adult female patron, K.S., who was nude in the adjacent room. While applying tanning lotion, K.S. glanced up to the wall partition and saw Steen’s camera. She screamed, and the salon owner rushed to investigate. Steen exited the tanning room, with his shirt untucked and his shoes untied. The salon owner called the police, and Steen confessed to having filmed K.S. He showed the officer his camera and was arrested for videotaping without consent in violation of Texas law. Later, investigators found other videos on Steen’s camera, including the April 3 video of C.B. Steen was facing state felony charges for video voyeurism,3 but when investigators identified C.B. and learned she was sixteen-years-old at the time she was filmed, the United States prosecuted Steen under the federal child pornography law.
The federal law, 18 U.S.C. § 2251(a), punishes “[a]ny person who employs, uses, persuades, induces, entices, or coerces any minor to engage in ... any sexually explicit conduct for the purpose of producing any visual depiction of such conduct .... ” The statute defines “minor” as any person under the age of eighteen.4 “Sexually explicit conduct” is defined as intercourse, bestiality, masturbation, sadistic or maso*825chistic abuse, or a “lascivious exhibition of the genitals or pubic area of any person.”5 The parties agreed that Steen’s film did not depict any of the first four items and thus focused on lasciviousness.
At trial, Steen moved for an instructed verdict, asserting the evidence was insufficient to prove beyond a reasonable doubt that the conduct filmed was sexually explicit or lascivious. The district court denied the motion, and a jury found Steen guilty of one count of production of child pornography.
Steen had no prior criminal history; a forensic examination of Steen’s computers found multiple adult pornographic images but no images of children. There was no evidence that the tanning salon video footage had been uploaded to Steen’s computer, nor was there any evidence, or allegation, that Steen had distributed any images. Steen was sentenced to fifteen years in a federal corrections center, the mandatory minimum of § 2251. He timely appealed.
II.
We review the district court’s denial of a motion for judgment of acquittal de novo.6 Evidence supporting a conviction is sufficient if a rational trier of fact could have found the essential elements of the offense beyond a reasonable doubt.7 “In assessing the sufficiency of evidence, we do not evaluate the weight of the evidence or the credibility of witnesses, but view the evidence in the light most favorable to the verdict, drawing all reasonable inferences to support the verdict.”8
The standard of review for lasciviousness determinations requires additional explanation, as our sister courts of appeal are split on the issue. The Third, Eighth, and Tenth Circuits have held that the decision of whether an image is lascivious requires de novo review because it involves a legal standard.9 The Ninth Circuit calls for clear error review, noting that a district court’s findings of lasciviousness should be upheld unless the appellate court has a “definite and firm conviction that a mistake has been committed.”10 Our own court has never stated a standard of review for lasciviousness in a case that challenged the sufficiency of the evidence. However, two sentencing cases in our circuit have applied a clear error standard to *826a district court’s lasciviousness determination.11 Following this precedent, we likewise apply the clear error standard to the jury’s conviction so far as it indicates a factual finding that the image was a lascivious exhibition of the genitals.
III.
Section 2251(a) makes it unlawful to “use” a minor “to engage in ... sexually explicit conduct” for the purpose of producing a visual depiction of that conduct.12 In assessing conduct under § 2251(a), we ask “two questions: Did the production involve the use of a minor engaging in sexually explicit conduct, and was the visual depiction a depiction of such conduct?”13 Steen clearly used C.B. for the purposes of producing a nude video, but the statute requires more — the film must depict sexually explicit conduct.14 Accordingly, this court has found, “a child could be used in the production of a photograph, but the image in the ultimate photograph could be one that did not capture the child engaging in sexually explicit conduct. If this were so, a defendant might be charged under a different statute — perhaps child molestation — but not child pornography.”15
Here, the parties focused on whether the video was a “lascivious exhibition” of C.B.’s genitals or pubic area. The jury instructions included a description of the six factors first proposed in United States v. Dost16 that have been applied in this circuit to assess lasciviousness.17 These factors are:
1) whether the focal point of the visual depiction is on the child’s genitalia or pubic area;
2) whether the setting of the visual depiction is sexually suggestive, i.e., in a place or pose generally associated with sexual activity;
3) whether the child is depicted in an unnatural pose, or in inappropriate attire, considering the age of the child;
4) whether the child is fully or partially clothed, or nude;
5) whether the visual depiction suggests sexual coyness or a willingness to engage in sexual activity;
6) whether the visual depiction is intended or designed to elicit a sexual response in the viewer.18
*827This list, however, “is not exhaustive, and no single factor is dispositive.”19 Any determination of lasciviousness “will have to be made based on the overall content of the visual depiction.”20 Moreover, we note that these factors have never been deployed where a defendant’s conduct said to be criminal under the statute at issue proved to be no more than voyeurism.
In considering the Dost factors and the statutory text, we find that the evidence was insufficient to find a lascivious exhibition of the genitals. First, the focal point of the visual depiction is not on C.B.’s genitalia or pubic area. Her pubic region is only visible for about 1.5 seconds.21 Moreover, the film did not accent the pubic area — to the contrary, the brief seconds the pubic region is visible, it is on the far side of the image’s frame. The first factor lacks factual support here. It does not point to a finding of lasciviousness.22
The second and third factors consider whether the setting or pose of the depiction is sexually suggestive or unnatural.23 Traditional settings that meet this standard are beds or bedrooms.24 A tanning salon is not a sexually suggestive setting, nor are C.B.’s movements unnatural for someone who is tanning. Because she did not know she was being filmed, she is, of course, acting naturally. Under certain circumstances, lying on one’s back may be sexually suggestive, but that is not the case when the non-sexual activity being displayed requires one to lie on the back. The fifth factor, suggesting sexual coyness, is irrelevant in this case because C.B. did not know she was being filmed. She neither acts coy nor willing to engage in sexual activity.
The fourth Dost factor is nudity, which Steen’s video satisfies since C.B. was fully nude for her tan. However, the Supreme Court has held that “nudity, without more is protected expression.”25 Surreptitiously filming a nude tanner, on its own, does not meet the standard for producing child pornography.
The sixth factor is the most difficult to apply — whether the visual depiction *828is intended or designed to elicit a sexual response in the viewer.26 Here, the primary evidence of intention to elicit a sexual response is that Steen surreptitiously filmed a nude 16-year-old. However, as a Missouri district court held in a similar case:
These videos could not be considered to have been intended to elicit a sexual response in the viewer any more than mere nudity would, which several courts have concluded is not of a sexual character. We do have some limited context ... that [the defendant] set up a camera ... but that context indicates nothing more than an attempt to capture mere nudity and is very different than a person ... telling a minor to undress, lay on a bed, and open his legs for a nude photo.27
Even if one assumes Steen was stirred by his voyeuristic pursuits, there is insufficient evidence to conclude that the image of C.B.’s genitals was designed to elicit a sexual response or whether, perhaps, merely being a voyeur excited Steen.28 When a photographer selects and positions his subjects, it is quite a different matter from the peeking of a voyeur upon an unaware subject pursuing activities unrelated to sex.29
We have previously adopted the ordinary meaning of the phrase “lascivious exhibition,” which we defined as “a depiction which displays or brings forth to view in order to attract notice to the genitals or pubic area of children, in order to excite lustfulness or sexual stimulation in the viewer.”30 Here, the government’s evidence cannot meet this standard.
IV.
We must conclude that Steen’s conduct did not constitute the crime with which he was charged, and the ease should not have gone to the jury. The judgment is REVERSED.

While there was no evidence that Steen knew C.B. was a minor — sixteen, not eighteen— Steen did not offer a lack of knowledge of minority in defense. We need not, hence do not, discuss the issue here.

A minor may, however, be "used” to engage in sexually explicit conduct without his or her knowledge — for example, if the minor was drugged or sleeping while being filmed. Nevertheless, the image captured must still display sexually explicit conduct in order to be considered child pornography.
