Ariana Grande's Tour Photography Policy Angers News Outlets

Ariana Grande is acting like a tyrant on her new tour ... at least, according to media organizations that are fuming over her photography policy.

Several major news outlets -- including the AP, New York Times, LA Times and 12 others -- have joined the National Press Photographers Association (NPPA) in protesting Ariana's photo policy on her current Sweetener World Tour.

The NPPA claims the tour contract she's making them sign to cover her concerts requires photographers to hand over all rights to their photos to her tour company, GrandAriTour, Inc. ... and they're only allowed to take still shots from a designated area during the first 3 songs.

If the photogs want to use their pics, they have to get written approval from Grande ... and even then, they can only use each photo once as part of a news story.

The 16 media outlets believe this is a massive overreach and flies in the face of journalistic principles ... and the NPPA president is urging members to refuse to sign Ariana's photography agreement.

No word yet if the singer will change her tune.
