Alan Cristea Gallery, London, until 2 July
Observation and representation of the body is central to Antony Gormley RA’s practice. In his latest work, the sculptor continues to explore the theme, questioning the ways in which the body is conditioned by the built environment. Experimenting with various techniques, Gormley has placed woodblock prints alongside his crude oil and petroleum jelly Body Print (made by Gormley pressing his own body onto the paper), asserting the freedom of the body in space.

The Fine Art Society, London, until 26 May
The artist Laura Knight RA made her name painting scenes from the ballet and the circus. This exhibition of etchings and acquaints transport viewers back to the seductive world of the theatre in the 1920s, revelling in its glamour whilst also disclosing private, quiet moments. The tonal effects permitted by printing techniques feel perfectly suited to the subject matter in its ability to evoke the atmosphere of the ballet, with some performers depicted on stage bathed in light, while others are submerged in shadow, rearranging their garments backstage. These beautifully poetic works demonstrate both technical virtuoso and a keen eye for intimate moments often lost behind the glitz of the stage.

Newport Street Gallery, London, 18 May – 16 October
An artist who has continued to garner attention throughout his career, Jeff Koons’ latest exhibition at Newport Street Gallery is sure to rouse just as much public interest as his last UK show at the Serpentine in 2009. In Now, Koons returns to the motif of the inflatable – a hallmark of his practice since his earliest years as an up-and-coming artist in the 1970s. Deploying state of the art technology, Koons recreates fragile air-filled blow-ups in stainless steel to create jarring paradoxes. Gaudy, playful and joyous, Koon’s works both tease and embrace American popular culture for all its idiosyncrasies.

Jerwood Space, London, until 19 June
Francesca Blomfield, Archie Franks and Dale Lewis have been selected as the 2016 Jerwood Painting Fellows. Now in its third edition, the prize supports outstanding emerging painters by awarding them a £10,000 bursary and mentorship by three distinguished UK painters: Phoebe Unwin, Jane Harris and Dan Coombs. RA Schools graduate Archie Franks has a distinct style of painting, with an excessive use of impasto endowing his canvases with a sculptural dimension. Dale Lewis’ work constructs powerful social commentaries through a deceptively naïve painterly style, whilst Francesca Blomfield chooses niche subjects – from human hair to tagliatelle – in order to experiment with colour and texture.

Megan Piper, London, until 19 June
Artist Tess Jaray RA presents three recent triptychs and two small paintings, in which she meditates on shifts in light, questioning, “at what point does colour turn into dark, or light, where it transcends itself and becomes another state?” She achieves her characteristic geometrically precise style by using a computer to draw the background and foreground components. Bold juxtapositions are a prevalent feature, yet within the same canvases there are also muted transitions in colour. Both subtle and acute, Jaray’s deceptively simple works reveal the emotional responses evoked by certain colour combinations.
