This image of the Rainbow Bridge in Tokyois is based on 366 single exposures from a time laps capture of 1.5 hours.
The main idea behind this image is to illustrate a full 1.5h captured time lapse in one single image. In this example the final image contains 366 single exposures.
To generate the above image the 366 exposures from the beginning of the time lapse (golden hour, left side) to the end of the time lapse (end of blue hour, right side) were averaged.
To calculate a smooth image with these 366 captures an own developed algorithm was used. This algorithm uses the image information of several images to generate a smart rendered result. The direct outcome of this algorithm can be seen here:
To generate the final static time lapse image (first picture) the city lights from the last captured image of the time lapse sequence were added. The Rainbow Bridge Time Lapse sequence is one of several time lapse of the YouTube Channel.
