Now that you have your photos and/or video to  complement your story, it’s time to pick the best photos and clips to  use and add the proper captions and titles.

If  you are using photos in your story, submit three out of your sequence  of photos with captions. Tell us why they are in the order they are in  and what part of the sequence they are from. Remember that cropping,  slight light adjustments for clarity and making a photo black and white  are ok, but do not edit your photos any more than that.

If  you are making a video, please submit the first edited 30 seconds. Your  video should include transitions, titles and any other effects you  would like to include. Remember, all music must be copyright-free.

This assignment will be due by Monday, September 12, at noon E.T.
