Analyse de l'application StarrySkyVideo pour le 30 décembre

This app is an ultra high sensitivity video application and can take pictures of the trajectories of stars moving in the night sky. Each frame of video is created as a bright image created by comparative brightness synthesis of up to 10 images. (Comparative brightness synthesis is a standard technique for taking beautiful starry sky photographs.) You can take video of the starry sky for a long time (5 minutes to 5 hours) and take pictures of the stars moving around the North Star along with the rotation of the earth. This is not just time lapse. Since it takes pictures with ultra-high sensitivity one by one, it takes video brightly even in the dark night. (Because shooting with compressed time, it will be fast-forwarded.) We recommend that fix the smartphone with a tripod etc. · Brightness: From brightness in the daytime, brightness suitable for night view, and even brightness to capture the starry sky can be specified continuously. · Recording time: It can be specified consecutively from minimum 5 minutes to 300 minutes (5 hours). · The time lapse interval (shutter interval) is automatically set and displayed from the brightness setting value. · The playback speed magnification can be specified continuously from 10 times to 300 times. The larger the magnification, the less the playback time. · Frame rate and playback time at playback are automatically calculated and displayed. If you cancel while photographing, it saves the video taken until then. Still images are saved at intervals of 10 frames of video.
