I have written a small app for track cycling competitions.
It requires an external text file with rider details (like country and race number). Before any competition I take a picture of the app’s timestamp with all cameras. During the competition the riderĀ is marked with the app with a single click.
Back at home, the pictures of the first camera are selected in Lightroom and the capture time is shifted exactly to the displayed time of the first picture. This process is being repeated for each camera. The app results then allow a “who is who” on each picture.
