San Francisco, Sep 18 (IANS): Tech giant Apple has introduced a Twitter "hashflag" to promote the filmmaking capabilities of its new iPhone 13 series, a feature lineup made possible through improved hardware and software enhancements.

The rather verbose "HollywoodInYourPocket" hashflag debuted on Friday in a promotional tweet from Apple's official account, meaning it does not currently appear on the company's main feed.

Featuring a clapperboard embellished with an Apple logo, the hashflag takes a cue from Apple's "California Streaming" event where the company introduced a slate of new iPhone 13 camera features, reports AppleInsider.

Along with across-the-board camera hardware upgrades, Apple is bringing a new "Cinematic mode" to both iPhone 13 and iPhone 13 Pro handsets.

Mimicking professional videography techniques, the technology uses machine learning algorithms to automatically shift focus to people, pets and objects, adding a depth effect for cinema-style shots.

"Cinema mode" can anticipate when another subject enters the frame and users can manually adjust focus after footage is captured.

The new feature, enabled by Apple's A15 Bionic chip, is shown off in a video embedded in Apple's tweet.

"HollywoodInYourPocket" should remain active through December 17, giving iPhone 13 users plenty of time to shoot and share their own "Cinematic mode" content, the report said.
