NOTE: This image is a focus stacked image of "Zeiss Batis Distagon F2.8 18mm.jpg" consisting of 22 images that were merged using Zerene Stacker Version 1.04 Build T2020-05-22-1330 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.
