Colleagues say famed architectural photographer Julius Shulman has died at his Los Angeles home. He was 98.

Gallery owner and representative Craig Krull says Shulman died Wednesday night and had been in declining health.

Shulman had more than 260,000 images in his archive when it was purchased by the Getty Center in 1995. Shulman's photos at one time sold for less than $50 each, but in later years, his photos were considered art and they brought between $2,000 and $20,000. He later collaborated with Juergen Nogai and worked late into his 90s.

His most famous work was called Case Study House No. 22, a black and white photo of a glass and steel frame home built by architect Pierre Koenig in the Hollywood Hills.
