The Kneeling Art Photography Project ( thekneelingartphotography.com ), under the direction of Portland artist Titi de Baccarat, opens their final Portland exhibit at the UMVA Gallery inside the Portland Media Center (PMC), 516 Congress St.   This community social justice/art project explores the meaning and evolution of the Take-A-Knee gesture by having Maine photographers turn their cameras on diverse Mainers who are fighting for social justice in the state.  There are eleven photographers taking part in the exhibit from seasoned professionals to people new to the craft.   Gallery hours are from 3 to 6 pm on Thursdays, Fridays and Saturdays until August 27th.  A special panel discussion, "The role of Art in the resolution of social conflicts", will be taped at the PMC studio and will be broadcast beginning the week of August 21st on Channel 5 and continuing for four weeks.  Donations are still being requested to fund the project and can be made at https://www.thekneelingar
