PSL 1-2
PSL 1-2 is the lowest band on a strict PSL rating chart, but it should be read with more caution than most people give it. In real use, this range is uncommon when the photo is clear and the face is visible. It usually means the image shows severe disharmony, extreme asymmetry, very weak structure, or photo conditions so poor that the rating has little confidence. A common mistake is treating a 1-2 score as a permanent identity label. It is better to read it as a signal that the current evidence is weak or that multiple visible categories are pulling down the estimate at the same time.
Photos can distort this tier more than users expect. Strong side angles, harsh flash, motion blur, wide-angle lenses, facial obstruction, or a tense expression can make normal proportions look much worse. If a tool returns a 1-2 from a low-quality selfie, the next step is not to panic. Retest with a neutral, front-facing image in natural light, then compare whether the low score repeats across more than one clean photo.
