Recommendation: Increase the distance between camera objective (lens) and subject. In-Field image demonstrating lens distortion Pinellas County Non-distorted booking image GeorgetownCPT 014407 FRT 25 Photo Consideration Aspherical Distortion: The aspherical elements of a lens help compensate for many lens aberrations common in simpler lens designs. Distortion presents in non-spherical lens and may demonstrate distortion at close distances. To compensate for distortion take the image at a minimum distance of 4 feet from subject without a zoom or greater than five feet and with a zoom. Automated Facial Recognition search outcomes can be significantly affected by aspherical distortion due to the nature of the enrollment/template generation of a distorted probe image. PCSO database images are collected via standardized collection processes and not prone to distortion.
