Presented in in HD and UltraHD sizes in my review of the Zeiss Loxia 50mm f/2 Planar.
This pair of aperture series is intended to show the differing visual impacts and associated tension created by relative illumination (vignetting), depth of field (sharp/unsharp), and motion blur (wind/water). All three effects combine and in effect are a sort of mini slide show across the aperture range.
A discussion on the complex nature of these seemingly simple images is included. The interplay of elements across the series is thought provoking as to which combination one might choose in the field, and also shows that making only one image variant can be a mistake under rapidly changing conditions.
