Cannon is presenting a free photography workshop July 16 as part of the Trinity River Corridor Project photo contest.  The class, at the Trinity River Audubon Center, starts at 6:30 p.m., and demonstrations start at 4 p.m. Sign up for the workshop here.

The deadline for the photo contest is Sept. 30, and the city is seeking entries that show the Trinity River’s natural beauty. Professionals, amateurs and youths can compete for $2,900 in prizes in the categories of  wildlife, forest, river and architecture/structure. Winners also get to have their photos displayed inside City Hall.

That Trinity River project isn’t going too well right now, but at least you can take advantage of the free class and cash prizes.
