Every morning when Peter Mello’s Twitter and Instagram followers check their feeds, they’ve come to expect a particular photo.

Rain or shine, snow or sleet, Mello’s daily post of Shipyard Park and the accompanying “Good Morning” message have become such a reliable ritual over the past four years that people are worried when they don’t see the familiar post.

“If I don’t post sometimes people ask what’s happened,” he said. “On occasion it’s a ‘Good Evening’ picture instead of a ‘Good Morning.’”

Mello lives with his wife, Jennifer, and kids, Luke and Joy, on the edge of Shipyard Park, where he moved 20 years ago.

And though he has always appreciated the view from his home, Mello didn’t set out to take a picture every day. A spontaneous photo from the deck of his home a few years ago turned into another and then another.

“It evolved from there,” said Mello, the managing director of Waterfire Providence.

A Fairhaven native and Tabor Academy alum, Mello’s parents gave him his first camera at age 8.

“All my life I’ve always carried a camera everywhere,” he said.

With the invention of the iPhone and compact digital cameras, it was only natural that Mello’s photography would expand to social media. His daily study of the shifting light and seasons at Shipyard Park is followed by almost 700 people on Instagram and more than 3,000 on Twitter.

“I feel that we live in one of the most beautiful places in the world,” he said. “This morning … I stood out there for twenty minutes, and I didn’t realize it was zero [degrees.] It was so captivating. It’s so still. It’s so quiet.”

While the park is usually silent when Mello wakes up each morning, he often envisions Shipyard Park as it was.

“I’m really interested in place – how place changes over time and how it stays the same,” said Mello. “I sit there sometimes and think about the ships that were built and that were launched from there during the whaling days, the families that sent people to sea.”

What his followers see is up to them.

“The important thing about art is how people absorb it and react to it,” Mello said.

One follower in Miami told him that her daily ritual is to look at his new post each morning.

Another person wrote, “I’m starting to feel like I’ve been there. Is this your intent?” “It kind of is in a sense,” said Mello.

As more people have become aware of his photos, they’ve asked Mello to publish them in a physical format.

“I’ve gotten lots and lots of requests to do a coffee table book,” he said.

Mello is planning to work with a local nonprofit to create a book of his Shipyard Park photos, along with information on the history and context of the area. Proceeds will benefit the organization.

“The working subtitle is ‘Exactly different every day,” he said.

In the meantime, Mello will keep posting his daily updates from his perch above the park.

“The idea that I could put something out there everyday that people respond to I find intriguing,” he said. “And if they didn’t, I’d still do it. It’s my daily ritual.”
