Later in the morning I went out to spray the invasive “Mile-a-Minute” vine with a biosafe herbicide.

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.

The Theta Z1 camera has Dual 3 mm fisheye lenses and uses two back to back 1.0-inch back illuminated CMOS image sensors with an output size of approximately 23MP (6720×3360). The camera can be programed to collect images in JPG or Raw (as DNG) format. The JPG images are transformed in the camera from two 360 degree fisheye images to a single 360 degree equirectangular format (6720×3360 pixels). The DNG images are the two individual 360 degree fisheye images (6720×3360 pixels). In order for the DNG images to be used the two 360 degree fisheye images need to be transformed to a single equirectangular image. Ricoh provides the Theta program (runs on Windows 10) that can be used to view and rotate the 360 degree images. No save or output capabilities. They also provide Ricoh Theta stitcher plugin for Lightroom that can be used to transform the dual fisheye images into an equirectangular image. You have to export the file to the Theta stitcher to do the transformation (one at at time), no obvious batch transform capability. I found that I could do batch transformations with the PTGUI.exe
