Merry Christmas to one and all. For today, I thought I would share with you one of my childhood favourites – the Danish butter cookie. My favourites are the ones with the sugar granules on its surface.
The first image is of the whole cookie. The subsequent images were taken with Sony A6000 + Leica Focotar-II 50mm F4.5 at F5.6. The UV-induced visible fluorescence (UVIVF) image was taken in the dark using three 365nm UV-torches to light the cookie. All macro images were created from focus stacking in Helicon focus.
The sugar granules do look very 3-dimensional in the cookie.
There is a slight fluorescence of the sugar granules induced by the ultraviolet light.
This is one cookie I had, and I ate it.
