rePhoto for Science

Science seeks to understand the world, and important data comes from cataloguing what is happening in different places and measuring changes. rePhoto helps imagery more accurately contribute to tasks such as measuring tree growth, snow depth, or stream erosion. We are excited (and funded) to support the use of rePhoto in any scientific discipline and welcome inquiries.

rePhoto for Personal Use

rePhoto lets you track changes around you, and you can rephoto your own pictures, and save them locally to see how downtown, or your garden, or your mustache have changed in the last year. rePhoto saves then-and-now pictures in a variety of formats that we have fun posting to facebook, twitter, and in family holiday letters.

Citizen Science Get involved.

There may already be rePhoto projects in your area, and your pictures would help record what is in our environment and how it is changing. Open rePhoto, look for a pin on the map near you and take a picture! Over time, you can see your contributions on the rePhoto Project page.


Time Lapse Study the past, rePhoto the present.

Remember how things were a year ago? With rePhoto, you can document and share changes over time. As you take a picture, there are several ways to see the previous image, to make it easier to accurately align the new image. This lets you (or your friends, or other rePhoto contributors) work to create time-lapses without specialized equipment or leaving behind a camera.
