It was the transience of light that enabled Monet to repeat his haystack paintings over and over again. Each captured certain light effects that often lasted but a few minutes. Each picture, therefore, was quite different from the last. Monet turned a mundane everyday object into an art form.

Is this what Jeff Clarke is trying to do? His Paintings, Drawings, Etchings exhibition, on show until September 12, presents us with the same ordinary objects as monoprints, etchings, mixed media, acrylic, pastel, gouache oil and watercolour and pastel. The result is a series of 30 still-life studies of everyday objects gathered from in and around his Oxford studio. Some appear to be arranged on an old wooden table in a garden shed, while the detritus from the kitchen stands on a more ornate octagonal table. For each work the objects are rearranged slightly, though the difference in the compositions is marginal. They are subtle changes - an onion is removed or added, a tea cloth is given stripes and then they are taken away, a coffee pot stands centre stage and is then pushed into the background. And all the while the colours are changing.

The medium in which they are painted changes too. It's remarkable just how striking a collection of everyday items can appear when painted in charcoal and pastel and viewed hanging next to a similar work in mixed media. Two thirds into the collection, the artist breaks out into colour. The result is stunning; it's as if he has opened a new paintbox and allowed all the pinks, the blues and the orange colours to leap out on to the canvases. Take his Pink Paraffin Can, Pink Table , this paraffin can was blue in the previous painting and the table a dusty brown. Then suddenly a shocking pink transforms the arrangement, despite the fact the objects have moved very little and the artist's perspective appears to be the same.

Monet was known to alter his canvases as he searched for a harmonious transition within his haystack series. I wonder if Jeff Clarke works on several studies simultaneously then alters them slightly to offer that same harmonious transition?
