Late Summer Nighttime Sky Over New Jersey.

Ricoh Theta Z1 camera set up to capture the night sky from my patio. Two versions of the 360 Equirectangular, 360 Little Planet, and 360 Tunnel view. The first ones processed directly with the jpg files from the Theta Z1 camera. For the second set, the DNG files (dual fisheye) were first processed with Capture One Pro then converted to single 360 Equirectangular 16-bit TIF files. By processing and converting the DNG files to 16-bit TIF files I was able to bring more detail out of the dark shadow areas in the images.

Summer Nighttime Sky Over New Jersey.

This was the third 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. This time I mounted the camera horizontally so one of the fisheye lenses pointed straight up. I wanted to see if this would make a difference with the star trails. 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. Interestingly, the camera adjusted the output with a correct horizon. It turned out that the horizontal settings were not as stable (wind jitter?). Fortunately, the PhotoShop CC settings I use to create the composite images (scripts, statistics, maximum) has a setting that tries to align images. Presumably using major common features in all of the 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

Gone to See Florida — 2019 Road Trip.

More composite images of the Granada Terrace park in St. Petersburg. In the last year the city has cleaned and repaired the structures. Apparently, the park has been used for weddings and other photo shoots. I’ve included composite 360 degree panorama, fisheye, little planet, tunnel view, and mirror ball views. The composite images were created using AutoPano Giga Pro software from a series of 39 images taken with a Fuji X-T3 camera and 16 mm f/2.8 lens (ISO 160, 16 mm, f/16, 1/60 sec).
