DIGITAL DARKROOM - WRITE A CAPTION FOR AT LEAST 1 PHOTOGRAPH IN LIGHTROOM CATALOGUE

This screen grab from Lightroom demonstrates that you can write a caption for your images within your lightroom catalogue. Using the Library function on the right of the screen, you scroll down to the captions section, where you can label your image, and add a caption. You can also give it a star rating, which may be useful for referencing your work later on.
