The world's most colourful celebrations Jeremy Hunter has spent over 35 years travelling around the world photographing its diverse celebrations and customs. His collection Let's Celebrate 365 is the result of this life-long interest, and an exhibition of the pictures is currently touring England and Europe. This photograph shows Muslims crowding Bangladesh's River Turag on their way to attend Bishwa Ijtema, an annual congregation held in Tongi, near Dhaka, which attracts over five million devotees. For many impoverished Muslims, it's an alternative to the Hajj to Mecca. Picture: Jeremy Hunter/Telefoto
