On First Friday, June 2, Carver Hill Gallery, 338 Main St., will open a photography show featuring four Maine artists — Nick Gervin, Jon Kolkin, Jim Nickelson and Liv Kristin Robinson — all working in very different genres. The opening will run during the city’s art walk, 5 to 8 p.m.

Gervin, featured solo in the upstairs gallery, is a full-time documentary/street photographer from Portland. In his current series, he documents the uninhibited energy of crowds getting out of bars and concerts; police at work; and firemen drenching buildings engulfed in flames. Gervin uses a bright flash on a Fujifilm camera, which creates a high contrast image and often solicits an expression of surprise from the subject.

Kolkin is an internationally recognized artist balancing a nearly full-time schedule as a professional fine art photographer with a career as a physician (recently retired), educator, global humanitarian and international speaker. His art is frequently described as minimalist, painterly and meditative. This current series is called Feathers: A Singular Journey.

Nickelson’s photographs are the result of his inquiries into the ways that we as a species grapple with the unknown and our relationship to the universe, particularly as those inquiries delve into the realms of science and cosmology. This show will feature work from two of his series: East of the Sun, West of the Moon; and Codex Natura.

Robinson was trained as an artist and art historian in New York City; and has been photographing the Maine landscape for more than thirty years. She is well known for her hand-colored, silver gelatin photographs of the late 1980s and ‘90s, documenting the evolving commercial and industrial waterfront of her adoptive hometown of Belfast. In this show of more recent digital work, Robinson continues to focus on the changing waterfront districts of Rockland and Belfast.

Carver Hill Gallery hours are Mondays through Saturdays from 11 a.m. to 5 p.m.; starting June 18, the gallery also will be open Sundays from 11 a.m. to 3 p.m.
