A photographer is proving that the one good thing about New Jersey — its view — is true.

Joseph DiGiovanna is shooting a 30-year time-lapse of the New York City skyline from his Weehawken window and is already four years into his project, CNN reports.

“It’s a living calendar that anyone can be a part of,” he said.

So far, DiGiovanna has over 4.2 million images capturing the Big Apple from the Verrazzano Bridge to the George Washington Bridge. He has a rig set up on his window with a camera mounted on a shelf, which takes a photo by itself every 30 seconds to create the timelapse.

DiGiovanna shares two timelapse videos daily on his Instagram account and website, which allows users to explore any day in his four years so far. His cameras even caught the July blackout that plunged New York City into darkness this year.

Since his camera amasses over 2,800 photos that take up to 36 gigabytes of data a day, DiGiovanna has to be smart with his photo storage. All photos are automatically transferred to a laptop, and the data is stored on two separate hard drives. DiGiovanna said he changes the hard drives four times a year and chose this method for security purposes. The backup drives are stored at his mother’s home in another state in case of natural disasters.

DiGiovanna even has a backup plan for blackouts, with an “uninterruptible power supply” he claims can keep everything running for several hours.

After trial and error, the photographer said his setup ended up costing about $15,000 if totaled up.

“I just gave up on trying to make it affordable,” he told CNN.

DiGiovanna has lived in Weehawken for 10 years but spent three years looking for an apartment to buy with the perfect view. He doesn’t plan on moving anytime soon, but if he does, he’s adamant to keep the project going through his 2045 goal — even if it means pre-organizing with prospective tenants.

“I would just set up an agreement with the renter, saying that the camera’s going to live there,” he said.
