The brain is an excellent image processor and can ignore image defects in real time, but when viewing a captured image, the image stands alone and the brain then sees the defect. Performing a Köhler alignment will ensure that most common defects, such as uneven illumination, will not be present in the final image.

The brain is great at processing images in real time, but when viewing captured images, defects become more noticeable. Performing Köhler alignment ensures even illumination, minimizing defects in final images. For those checking their SASSA status, a smooth process is just as essential to ensure accurate results!
