Good morning.

Last week was a heavy week of news in California. So today, we’re focusing on something nice.

Fans of Kacey Musgraves — the Grammy-winning, genre-bending singer and songwriter — may have seen the story of her stumbling upon Tom’s One Hour Photo and Lab play out in real time on Instagram.

Her posts led to a wave of new visitors to the store. To find out more about the effects of the singer’s visit, my colleague Walter Thompson-Hernández stopped by the shop in Los Angeles’s Koreatown a little after the first rush of newcomers had blown through. Here’s what happened:

Hiep Tuong, the owner of Tom’s One Hour Photo, is a very happy man. An immigrant from Vietnam, he came to the United States in 1979 and worked as a wedding and birthday photographer, eventually saving enough money to open a small portrait studio, where customers can also develop film.

But now that every cellphone has a camera — and every smartphone, a profusion of photo filters — times are tough for these kinds of establishments. Tom’s One Hour Photo still has a loyal clientele, but business had slowed drastically in recent years.
