Thousands of revellers generated a carnival atmosphere on a disused airfield as Scotland's biggest music festival celebrated its tenth birthday. By mid afternoon on Saturday, the sun was shining brightly for the T in the Park weekend event at Balado, near Kinross, after getting off to a cloudy start.
Rock giants REM headed the opening day before a sell-out crowd of 55,000 people.
More than 120 acts are expected to perform across nine stages before Grammy Award winners Coldplay close the festival on Sunday night.
Tayside Police have praised the crowd for their good behaviour so far and said there had only been seven arrests for minor offences.
'Strength to strength'
T in the Park promoter Geoff Ellis spoke of his pride as the event marked its tenth birthday.
"I keep pinching myself when I think that we have got to ten years," he said.
"Some events go past their sell-by date and struggle but we have gone from strength to strength.
"And while this weekend is a milestone, it is not a plateau. We have not peaked yet."
 The White Stripes were due to play on Saturday |
T in the Park's 10th anniversary bash sold out in record time but promoters suffered a last-minute blow when The White Stripes pulled out of Saturday's main stage line-up.
A statement from the band said vocalist and guitarist Jack White had fractured his finger in a car accident in Detroit.
The Flaming Lips, who had been due to headline the King Tut's Tent, were promoted to fill their slot near the top of the main stage bill.
Away from the bands and the Slam dance tent, festival-goers can also experience the T Garden - described as a botanical garden with DJs - and a beach which has been built on site.
Music fans are also being given the chance to become involved in Oxfam's campaign against the international arms trade.
Charity campaign
It is offering people the chance to join a photo-gallery of a million faces which it hopes to present to the next big UN conference on arms control.
Oxfam says the UK is one of the world's top three arms exporters.
The charity wants action against British arms brokers wherever they operate and it wants an international arms trade treaty.
