I am amazed by the range of colors the sun emits during the day. I wake up in the morning and the first thing I do is turn off the alarm clock by the window. When I reach my hand to the alarm, I notice the color of the wall lit by the morning light. Most of the time, it is blue. But sometimes it is a deep blue, and other times, a pale blue. During the day, I notice the presence of daylight as cloud covers the sun and darkens the room, then the light comes back as the cloud clears, as if the sun is breathing. As the sun approaches the horizon, a white wall in my room turns to yellow. I notice that the space is filled with the same color, for one minute, and then the light fades away as the sun sets.

Depending on the weather, the season, and time of day, the sun emits different colors of light due to the refraction of light and the distance of the sun to the earth. The gradual shift of the color temperature of each day is subtle yet unique.

This photograph is the result of my observation of daylight throughout a day. I set up a piece of paper by the window as the sun comes up, take a picture on transparency, patiently wait until the color of day light changes, take another picture, and continue this process until the sunset goes down.

I compose an image by scanning the slide films of daylight color. I start with a blank file whose vertical axis invisibly represents time from sunrise to sunset during the day the series of slide films are captured. I align each slide film at the exact timeline when the slide film is recorded on that day, gradating the colors in between. Oddly the resulting image looks as if it is a painting, although the way I compose an image is not similar to that of a painter because the colors I am applying is not mark or gesture on a canvas. The colors I apply to my work are obtained photographically, so they are indexical to the time they are observed. These are timescapes of past days.
