I developed this experimental photography method because I wanted to create a stylized way of showing time passing in one image.

The simple process

You shoot a time-lapse. You take strips of each image. You put them all together.

The complicated process

Before starting, there's some math to do. There are three variables: the length of time to capture, the size of the final image, and the width of the strips. The time-lapse framerate is the product of image size (width or height, depending on if the strips are vertical or horizontal, respectively) divided by strip width divided by capture time. For example, for a 1080p image with 2px-wide horizontal strips that captures 90 minutes, the frame rate should be 6fpm (1 frame every 10 seconds).

Once it's recorded, I put the video into Davinci Resolve to trim and color grade the video, then export the whole thing as individual images. Once I have my images, I mass import the hundreds of images into Photoshop and go through the painstaking process of cutting tiny strips out of each image one after the other. I've found a couple ways to cut corners, but one day I hope to automate this process because it still takes around an hour for images with only a few hundred frames. Once you get into thousand-image territory it gets a little ridiculous.
