This is your final.  You will be working on it throughout the semester and it will aid you when uploading photos at AP Central.  Again you need:
15 photos exploring one concentration or theme ( Number of finished projects varies per student)
5 photos showing a mastery of skills in a variety of media (they can be part the same as your concentration or other works)

EVERY SKETCH, EVERY ALTERATION, EVERY PROJECT, needs to be photographed and uploaded here.  From here you will choose the 15 photos you need for your concentration (in case there are more) and the 5 for your mastery of skills

Use the gallery items/enhancements if you so choose to make your finished portfolio shine.  Feel free to add your own items.
