The first music festival to be slotxo held in Northern Ireland since the Covid-19 pandemic began on Friday.
Stendhal Festival, which is based in Limavady, County Londonderry, welcomes back fewer numbers than previous years.
The festival attracted a 10,000-strong crowd in 2019, but this year about 2,500 visitors are expected.
It follows Stormont's announcement that live music in Northern Ireland could resume from 5 July, as part of further relaxations to Covid-19 rules.
While music performed indoors is restricted to an "ambient sound level" with screens placed in front of musicians, no volume restrictions apply to live music at outdoor events.
Stendhal Festival was established in 2011 and has grown into one of the biggest music and arts events in Northern Ireland.
