You need to submit your image in the “hand in” folder under DP11 > ExposureAssignment.
Naming your folder: eg. John Smith is SmithJ
In Lightroom, create a name for your title. It should clearly indicate what the picture is. eg. DOF-shallow1, DOF-shallow2, ISO-high1, etc….
Also, enter your name as the creator and maybe a description of your picture.
