Eight-Years Ago Today. Indoor Cactus Garden in New Jersey.

I take the cactus in for the winter and rarely see them blossom. I was about to move them outside when I noticed one of the small barrel cacti had small flowers. I couldn’t get the level of detail I wanted with a single macro image. Instead, I made a composite of 24 focus stacked images using a Nikon Df camera and 105 mm f/2.8 VR macro lens (ISO 100, 105 mm, f/4, 1/125 sec) and SB-910 flash (EV -2). The images were processed using Helicon Focus: [Method B (depth map, R = 8, S = 4)].
