Red Rover time-lapse video of the day. Today’s project was to attach the Woods PD-25 post-hole digger on Red Rover. Took a while to get it installed. Read the safety manual several times. When completed, dug the first of 170 holes for the deer fence project. Small issue of a bolt rubbing one of the safety shields, and a shear bolt falling out (didn’t shear, nut must not have been on tight enough). Tech from Belle Mead motors stopped by to fix the rubbing issue.

Colorful Clouds at Dawn. Composite of eleven images taken with a Leica CL camera. Images were processed with Capture One Pro 22, including the panorama stitching. This is a new feature in the just released update to Capture One Pro. Previously, I would have stitched the images with AutoPano Giga (a program no longer supported) or PTGui. The stitched image size is 16309 x 5365 pixels. At 300 dpi, the print would be 54.4″ x 17.9″.

Night sky and star trails using a Leica Q2 Monochrome camera. One limitation is the camera takes a 2nd blank (shutter closed) exposure to subtract out sensor noise anytime the exposure is > 4 seconds or the ISO is > 100. With other cameras from Nikon and Fuji, I am able to turn the long exposure noise reduction off, Also, when taking an interval collecting both DNG and JPG the camera stops collecting images after 5 minutes (60 exposures). When recording DNG images, the camera collects 50 minutes (600 exposures). Images were processed with Capture One Pro, and the star trails created using PhotoShop (statistics, maximum).
