Photographic Frontiers Study Group meeting. Just a reminder that this evening we will have an open meeting in which attendees can present photographs that they would like to discuss. If we don’t have enough photographs to fill the meeting, the group’s co-director, Thomas Walsh, will give a presentation on his adventures photographing the recent total eclipse in Casper, Wyoming. In keeping with the mission of this subgroup of Flatirons Photo Club (education and mutual support), the meeting will focus not just on what each presenter has to say about the photographs but also on constructive criticism, provided that is desired by the presenter. Feel free to bring up to 10 photographs on thumb drives. The meeting will be held from 7 to 9 p.m. at Boulder Digital Arts, 1600 Range St., Boulder, CO.
