Contact me if you are interested in a Time-lapse Video of the session at the Birdfeeders. My setup for the birdfeeder images is a Nikon D850 camera and 200 mm f/2 VR lens set to take one image every 5 seconds over a 5 hour period (~3600 images). The new time-lapse video format is 720p (1080 x 720 pixels) and 1 frame/second. The length of the video is about 1 hour in a 1 GB MP4 file. The previous time-lapse videos of the birdfeeders were at 12 frames/second, and to be honest were too fast to identify the birds.

Summertime Backyard Nature in New Jersey.

I noticed several articles on the net about scientists testing the 3,200 megapixel camera for the Vera Rubin Observatory’s telescope by taking an image of a Romanesco broccoli. It didn’t look like the Broccoli that I am familiar with but was fascinated by the Fractal pattern. Romanesco broccoli was available online at Whole Foods so I ordered one for my weekly grocery delivery. It looks more like a Cauliflower, but green with Fractal like towers. I used it to create my version of a high-resolution focus-stacked image. I set up a Leica SL2 camera with a 50 mm f/1.4 lens on a tripod with a 10 cm focusing rail. The SL2 camera has the capability to take 187 megapixel images using pixel shifting technology via a Multishot mode (available after a Firmware 2.0 update). I took 87 high-resolution images (ISO 50, 50 mm, f/1.4, 1/10 sec) moving the camera forward in ~1 mm intervals. This resulted in 16,269 megapixels of data. The images were processed with Capture One Pro and then Helicon Focus to afford the following focus-stacked (12510 x 10008 pixel, 717 MB) images. The images is in focus for the full depth of the Romanesco broccoli. I love the natural Fractal patterns. You can see that there are some sections where black mold has started growing. Now to clean it up and figure out how to cook it for dinner.
