A shout-out to this year’s Karsh Prize winners. Given annually to three talented students of photography at the School of the Museum of Fine Arts, the Karsh Prize this year went to Hannah Bates, Amanda Elam, and Kirk Lorenzo. The winners’ works will be on view in the SMFA’s “Graduating Students and Award Recipients Exhibition’’ through May 21. . . .
