RePhoto, or repeat photography, is the act of taking a new picture from the same view point as an older picture, often to visually measure changes. This app was written primarily to support citizen science projects that record and measure plant life. If you don’t want to participate in Project RePhoto, or are not in an area of the world with any active projects, you are still welcome to use the personal rephotography feature on images in your own photo album. More information about ImageQuest and Citizen Science is general is available through our website, projectrephoto.com.
