You are rarely alone in Taipei. The city is filled to the brink with temples and their worshipers, with hectic business people, shoppers, and aimless tourists. Add to this the tantalizing smells and sounds of the many night markets and the never ending lines of motorcycles and Taipei emerges as a city of boundless opportunities and adventure. Neither are you alone on Elephant mountain, the most famous viewpoint of Taipei, particularly during a beautiful sunset. I joined the dozens of spectators on a warm evening in November. Looking at the city from a bird’s perspective made all of Taipei’s hustle recede into the background. As the last rays of sun pierced the Taipei 101 tower, the city transformed into an almost serene image. I took the photo with my APS-C 16mm F1.4 lens and it is composed out of three images from a captured time laps during this sunset. While this place was very crowded I took the picture series without tripod, but I was able to use the railing of the platform.
The main effect of using a circular polarizer filter while capturing a rainbow can be seen in the following animation:
To generate this gif animation a circular polarizer filter was used. The filter was rotated stepwise to show the appearance and disappearance of the rainbow. This animation of the rainbow at Niagara Falls contains a total of 13 single exposures.
A polarizer filter can help to increase the saturation of the rainbow in an image, but it also can eliminate the polarized sun reflection in the image. Therefore, depending on the used focal length it might be necessary to capture several images with different polarizing filter settings to bring out the colors of the rainbow in the entire image.
The use of a tripod is highly recommended, but it is not mandatory thanks to post processing. The shown animation was captured hand-held while rotating the circular polarizer step by step.
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:
Result of the 366 smart averaged images
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.
