Summer Nighttime Sky Over New Jersey.

This was the second night in a row with a clear sky. The moon would rise a hour later. I decided to do star trails again with the Ricoh Theta Z1 360 degree camera. Camera settings (ISO 400, dual 2.6 mm fisheye lens, f/2.1, 60 sec). The images were processed with PTGUI, Capture One Pro, and Photoshop CC to create the following 360 degree Equirectangular Panorama, 360 degree Little Planet View, and 360 degree Tunnel View images. If you look close, you can see some firefly trails.

Summer Nighttime Sky Over New Jersey.

With a clear night sky, I decided to try the new Ricoh Theta Z1 360 degree camera to create some star trails. I set the camera up on my back patio (ISO 400, dual 2.6 mm fisheye lens, f/3.5, 60 sec). The camera can collect 358 raw (DNG) images which corresponds to just under 5 hours at 60 second exposures. The images were processed with PTGUI, Capture One Pro, and Photoshop CC to create the following 360 degree Equirectangular Panorama, 360 degree Little Planet View, and 360 degree Tunnel View images. I’ve also included a time-lapse video of the night sky

Summertime Backyard Nature in New Jersey.

Walkabout with a new Sigma 100-400 mm f/5-6.3 telephoto zoom lens on a Leica CL camera. Hand-held, the combo is a bit awkward with the camera being smaller than the lens. On the smaller sensor (APS-C), the field of view is equivalent to 150-600 mm. The invasive “Mile-a-minute” vine is taking over. Flowers in the soft-pots on the patio. Zinnia, Cosmos, Coreopsis, Zinnia, Sunflower.

Need to catch up on mowing the lawn. Finally a clear day when the grass was dry.

Summertime Backyard Nature in New Jersey.

Walkabout with a new Sigma 70 mm f/2.8 macro lens on the Leica SL2 camera. Flowers in the soft-pots on the patio. Zinnia, Cosmos, Coreopsis, Forget-me-not, Sunflower. Hand-held, but somewhat windy out. Narrow depth of field, so not all are completely in focus. Something I need to work on. This camera does have a higher resolution mode (but not a focus stacking mode). The higher resolution mode requires the camera be stabilized on a tripod. The same is true for the focus stacking mode on the Fuji X-H1 or Nikon D850.

Summertime Backyard Nature in New Jersey.

Afternoon at the Birdfeeders: Mourning Dove, Red-bellied Woodpecker, Downy Woodpecker, Blue Jay, Black-capped Chickadee, Tufted Titmouse, Gray Catbird, House Finch, Song Sparrow, and Northern Cardinal.

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