For decades, photographers have tried to simultaneously describe, inform and critique. Lewis Baltz, Robert Adams and Richard Misrach, for example, worked the so-called New Topographics angle in the 1970s, by which technical, modernist, understated aesthetics were combined with a critique of urban expansion and environmental degradation. The images in Hong Kong Four-Cast have similar concerns, shot by four photographers with strong technical skills - Wong Wo-bik, Hisun Wong, Lau Ching-ping and Almond Chu - and connected through a sense of loss and ruin.

Wong Wo-bik's 1997 photos of the defunct Lai Yuen Amusement Park, digitally reproduced in large scale for the first time, are filled with a fabricated nostalgia. Hisun Wong's carefully fashioned black and white inkjet prints of former colonial buildings are pristine examples of a modernist's obsession with tone, light and form.

Time and detachment inform Lau's beautiful, but alienated, cityscapes, combining muted colour and an astute sensitivity to light. And Chu's large-format colour images of garbage revel in a structured, technically perfect look at waste in Hong Kong landscapes.

Yet, considering its approach and subject matter, Four-Cast lacks a coherent position from which to speak, confusing the descriptive act of showing with that of saying something informative or critical.

Unlike New Topographics, much of the work does little more than aestheticise banal, nostalgic or unwanted sites - as opposed to meaningfully engage with them. Adding to this is an over-crowded installation, with photographs framed then hung inside glass cabinets or just oddly laid on a tabletop. This creates an incongruous aura of preciousness, due more to gallery limitations than the imagery. (Lau's elegant installation of tiny, affected postcards are exceptions.)

Even with its lack of intensity and focus, the show is not to be missed. These are four of the city's best photographers. But if you're expecting an exciting, challenging show or an exploration of current issues in contemporary photography, you may be disappointed.
