In the coming months, Twitter plans to update its mobile applications to introduce filters for photos that will allow people to share altered images on Twitter and bypass Instagram, the popular mobilecentric photo-sharing network, according to people who work at the company but asked not to be named as they are not allowed to discuss unannounced projects. The filters on Instagram make photos look like they were shot with 1960s Kodachrome or with 1890s sepia tone film.

Although adding photo filters to Twitter may seem like a trivial addition to a social network that processes nearly a billion 140-character missives every two days, it could prove to be an important part of the company’s business.

As most smartphones are now equipped with high-resolution cameras, photography and mobile devices go together like peas and carrots. Flickr, which was once the go-to photo-sharing site on the Web, has since seen an exodus of people who have opted for Facebook or Instagram. Twitter has proved to be very popular among advertisers who want to reach people on smartphones, where the company’s audience tends to flock.
