It gives an amateur photo look.<h3>Usage</h3>Start with the trigger word <code>UnderboobRK</code>, then describe the woman (skin, hair), the top (cropped t-shirt, crop top, bikini, lifted tank top) and how much of the underside of her breasts it shows, her pose and the place, and end with the light. Naming the top and the underside of the breasts brings out the effect the most.<code>UnderboobRK, Photograph of a woman with &lt;skin&gt; and &lt;hair&gt; in a &lt;color&gt; &lt;cropped top&gt;, showing the underside of her breasts. She is &lt;pose&gt; &lt;place&gt;. The lighting is &lt;light&gt;.</code>Recommended weight: 1.
