Photojournalism has traditionally been a male-dominated field.

But throughout history, women have made their mark on the industry.

Yunghi Kim is one of them, and she wants to make sure her peers get the recognition they deserve. Especially those who started their career in the film era, before the advent of the digital camera.

"They were courageous. They were fearless," she said. "And they were trailblazers because they were in a sea of men."

Kim says there is a "silent generation" of women photojournalists who are often overlooked. Maybe their work was never digitized. Maybe their work is sitting right now in the basements of newspapers, magazines and photo agencies, buried in an archive they can't access and may never be able to.

So Kim took it upon herself to do something about it. She started a website, Trailblazers of Light, to honor these pioneers of photojournalism.

More than 500 photojournalists are listed on the site, going back to the late 19th century. These women have reported from all over the world, often in war zones and other dangerous places. Many of them broke glass ceilings where they worked and paved the way for future generations.

It's important that these women, and their contributions, are not forgotten, Kim said.

"It had to be done," she said. "It was a sense of duty to the women."
