Moving into August, this week鈥檚 top exhibitions reflect upon life in cities around the world. From London to Perth, these shows use stylised photography and bold installation to question and document the impact of globalisation.

Comprising work by 50 artists spanning from the late 19th century to the present day, this collection offers new perspectives on the nocturnal capital through portraiture, documentary, conceptual imagery and film. Until 11 November.

Celebrating 12 Welsh and Wales-based photographic talents, this show explores timely subject matters including eco-living, cultural diversity and the experiences of refugees and asylum seekers in Cardiff. Until 29 September.

Holzer鈥檚 digital, text-based installations deliver powerful messages, bringing into focus ideas of media stimulation and information overload whilst questioning belief systems and power structures. Until 31 July 2019.

Positioning Perth City as a centre for change, Daniel Gevaux鈥檚 intriguing images record its urban and natural spaces, reflecting on ideas of growth and globalisation in the 21st century through colourful documentary pieces. Until 25 August.

Intrigued by the metropolis, Christian H枚hn鈥檚 monumental works tap into ideas of alienation and anonymity, reflecting on the cultural and environmental impact of urbanisation in Beijing and Dubai. From 4 August.
