Birds of the day. Individual images in the slideshow are available in my PhotoShelter Gallery.

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).
