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.

Morning at the Birdfeeders: Mourning Dove, Red-bellied Woodpecker, Blue Jay, American Crow, Black-capped Chickadee, Tufted Titmouse, White-breasted Nuthatch, Gray Catbird, House Finch, American Goldfinch, Song Sparrow, Northern Cardinal, and Rose-breasted Grosbeak.


Afternoon at the Birdfeeders. Individual images in the slideshow are available in my PhotoShelter Gallery.

Contact me if you are interested in a Time-lapse Video of this 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.

Backyard Springtime Nature in New Jersey.

The birds for the day are Brown-headed Cowbird, Mourning Dove, and Eastern Phoebe. The Eastern Phoebes are responsible for the bird nest above my front door. They also appear to be catching the Carpenter Bees that have been drilling holes in my Cedar siding. A good thing, so I will leave the bird nest alone. Yesterday it was very warm, and many California Poppy flowers opened. The California poppy flowers close at night and open again the next day when warmed by the sun. The first outdoor Red Poppy flower of the season bloomed. The poppies this year were self seeded from last year’s flowers.

Indoor Springtime Nature in New Jersey.

I finally got the PhotoShelter plugin that allows me to upload images from my PhotoShelter Gallery to this photoblog working again. While we are all “sheltering in place” and “social distancing” I can catch up on my images and posts. Ambient Weather changed some things and I am trying to get the local weather conditions from my weather station to display at the end of the post again.

Today’s image is a focus-stacked Orange Gazania flower blooming in one of my AeroGarden indoor hydroponic farms. The flower closes at night and then reopens when the LED lights come on again.
