The Fifth Think Pink Photo Competition is ending soon, with submissions due by September 27th at 11:59 PM EST. This contest, hosted by Dive Photo Guide, encourages photographers to share their best pink-themed underwater photos. Fees for entry range from $15 to $50, with proceeds supporting breast cancer research. Contest winners will earn trips to tropical dive resorts in the Philippines and Papua New Guinea. Dive into the Pink is a nonprofit organization founded by a breast cancer survivor to raise funds through diving activities.
