Summary
[edit]DescriptionDetail of pale white dove feather - horizontal rhachis with gap between barbs - DSG2033-1 - 2021-04-04 (HiRes).jpg |
English: Midsection of a pale white dove feather. The rhachis (shaft) is arranged horizontally with closely intertwined barbs above and below. As found, one row of barbs remained disconnected, forming a gap. A series of images was processed as a HiRes focus stack that resolves every single barbule across the image.
Deutsch: Detailausschnitt einer fahlweißen Taubenfeder. Vom querliegenden Federschaft (Rhachis) zweigen die dicht gereihten Federäste ab. Die Lücke zwischen den Federästen war schon bei der Entdeckung vorhanden. Die initiale Bilderserie wurde per Fokus Stacking zu einem äußerst detailreichen Bild zusammen gesetzt, in dem jeder einzelne von den Schäften abgehende Strahl (Bogenstrahl und Hakenstrahl) im Detail sichtbar ist. |

NOTE: This image is a focus stacked image of "Midsection of a pale white dove feather" consisting of 32 images that were merged using Zerene Stacker Version 1.04 Build T2022-04-21-0715 (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.
