The micro-blogging site is working with Aviary to power the filters and effects, which was selected as Flickr's online photo editor back in April.
Twitter is offering eight filters: vignette, black and white, warm, cool, vintage, cinematic, happy, and gritty. To use one, upload a photo to Twitter as you normally would by clicking the photo icon on the compose screen and selecting your image. Three photo options will appear at the bottom of the screen a auto-enhance wand, filters, and crop. Select the filter option in the centre to alter your pic. Swipe left to see your photo in all eight filter options. Once posted, filters will show up on a newsfeed just like twitpics do now.
"Every day, millions of people come to Twitter to connect with the things they care about and find out what's happening around the world," Twitter said in its blog post.
"As one of the most compelling forms of self-expression, photos have long been an important part of these experiences."
Rumours about a Twitter-based filtering options emerged this weekend in a report from All Things Digital. The blog pointed to the string of black-and-white filtered photos Twitter chief Jack Dorsey had been posting since the beginning of December as possible proof that filters were in the works.
Twitter stressed that "we've been making it easier and faster to share and discover and enjoy great photos on Twitter every day," a nod to its recent spat with Instagram. The Facebook-owned photo site recently pulled its support for Twitter Cards, which resulted in some Instagram photos showing up cropped on peoples' Twitter feeds. Then, over the weekend, Instagram photos seemingly disappeared from peoples' Twitter feeds altogether, though the links remained.
Not to be outdone, Instagram released an app update of its own, with a new filter and some new camera options.
Meanwhile, the social media photo wars continue, as Google rolled out an Android version of the Snapseed photo app from Nik Software, the Instagram rival that Google acquired in September.
In other Twitter news, the company announced that its new profiles, which began rolling out in September, will be available to all users as of Wednesday. Anyone refusing to upload a cover photo will see only the default grey image on their profile page.
