NOTE: This image is a focus stacked image of "Ensign Midget - model 22 camera in comparison to a type 135 film roll" consisting of 13 images that were merged using Zerene Stacker Version 1.04 Build T2018-07-19-1515 (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.
