Backyard Autumn Yard Work in New Jersey.

After many days of rain, the sky was mostly clear and the grass needed mowing. I mounted a Garmin VIRB 360 camera on my lawn tractor. Then made the following time-lapse videos using Photoshop CC. The forward lens of the camera faced the direction the tractor was going, so in the 360 panorama view I am split on both sides of the image based on how the image was stitched in-camera .

Backyard Autumn Nature in New Jersey.

Today, I continued evaluating a Garmin VIRB 360 degree camera. The first thing that I like about this camera is that it has external control buttons, and a small LCD screen on the top to display the camera settings. The other cameras that I am looking at all require a smartphone or tablet for set-up and use. The Garmin camera also has a rechargeable battery that can be swapped out with a fresh battery. Two of the other cameras only have internal batteries. The Garmin camera can also be run with an external power supply connected to the micro USB connection port for shoots lasting more than 1 1/2 hours.

I initially set the camera up on my patio to do interval shots for a time-lapse video. In the camera (photo) mode you can set the interval time ( 2, 5, 10, 30, and 60 sec). There is no setting for duration, which presumably means the camera continues to take images until the battery (power) runs out, the memory card is full, or the run is manually stopped. The camera also has an option to change the lens mode (360 degrees, forward lens, rear lens, and raw). The 360 degree mode provides an in-camera stitched 360 degree panorama image. The forward and rear lens modes provide a geometrically corrected 16:9 image from the front or rear lens. The raw mode provides separate fisheye images from the front and rear lenses. It should be noted that raw does not mean that the image is in a RAW format. All of the images are JPG format.

The time-lapse video was created using Photoshop CC with no adjustments. The camera is automatically controlling the exposure, and white balance. The clouds are a bit blown out, and shadow areas a bit dark. I then connected an external power source which you can see in the next two short time-lapse videos while I am working on the garden in the patio. One converted to a “Little Planet” view and the other a “Tunnel View” using Photoshop CC.

I then left the camera running for the rest of the afternoon into the evening to see how long the external battery (GoalZero, Venture 30) would last. The camera was still running and taking pictures after 6 hours. For these time-lapse videos, I processed the images with Capture One Pro to decrease the blown out areas, and increase the shadow areas. This did take a lot of processing time.

Home Cooking. Hearty Whole Grain Rye Bread.

Another day of rain. The weather for the last few weeks is more like Seattle, Washington or Bergen, Norway. I decided to make some hearty whole grain rye bread. I ran out of rye flour, and the new batch I got is the whole grain version from Bob’s Red Mill.

I set up a Insta360 One camera to take images for a time-lapse video of the process. While in Germany earlier this summer, my brother showed me the Insta360 One camera. I was impressed because it could take 360 degree images, and convert them into “little planet” or “tunnel view” images. I have created these type of images for several years by taking 20 or more images with a high-resolution DSLR or mirrorless digital camera, and then using the AutoPano Giga program to convert the images into a 360 degree view. (Note, I just read on Thom Hogan’s blog that Kolor will no longer be selling the AutoPano Giga program.) The process would take hours of processing, and required fast computers, and lots of memory. The images ended up being very large — often over a gigapixel in size. So I decided to try this new camera. Granted the image size would not be as large, but if only viewed on the internet does it matter? Also I would be able to make time-lapse 360 degree videos. I’ve created three time-lapse videos of the bread making (Panorama, Little Planet, and Tunnel View). Let me know what you think. There are some idiosyncrasies with the Insa360 One camera system that I will talk about later when comparing with other 360 degree camera systems.

Hearty Whole Grain Rye Bread Recipe: Rye Flour (1 cup); Sprouted Wheat Flour (1 cup); Bread Flour (1/2 cup); Sorghum Flour (1/2 cup) Flax Seed (1/4 cup); Chia Seed (1/4 cup); Dill Seed (1 tbs); Anise Seed (1 tbs); Caraway Seed (1 tbs); Fennel Seed (1 tbs); dry milk (1/4 cup); cocoa (1 tbs); instant coffee (1 tbs); salt (1 tsp); egg (1 large); flax oil (2 tbs); water (1 1/4 cup); Maple syrup (1/3 cup). Above ingredients added to Panasonic Bread Bakery. Yeast (2 tsp) added to yeast hopper and the unit set for Whole Wheat Bread (Rapid) and started. Three hours later, the loaf of bread was removed and allowed to cool.

Backyard Summer Nighttime Sky Over New Jersey.

For the first time since I returned from Germany, the sky was predicted to be clear overnight. I have been wanting to try the 8-15 mm fisheye lens (that I borrowed from my brother) for doing some star trail images, and night sky time-lapse videos. I did have an issue with condensation on the very wide lens in the early morning hours. I have had the condensation problem on other wide lenses (14 mm, 14-24 mm) in the past, and may need to fashion a small tape heater on the lens.

White-Ram. Roadtrek RS Adventurous RV.

I picked up my new Roadtrek RS Adventurous RV at Campers Barn in Kingston, New York. The RV is built on a Dodge Sprinter body with a Mercedes diesel engine by the Road Trek folks in Canada. I drove the RV on my “Gone to See America 2009” road trip. This trip took me by highway to Bellingham, Washington, by sea on the Alaska Marine Highway to Haines, Alaska, and on road again (through Canada) to Anchorage, Alaska to take part in the Nikonians ANPAT 9, and then back to New Jersey via the Alaska-Canada highway.
