We are sitting in the lobby of the National Theatre in the early afternoon waiting for the photocall for Dara to begin. Six or seven photographers, one woman, all dressed in jeans and dark jackets with large camera bags, some on wheels. There is not much conversation. As a relative newcomer I don't normally speak, but on this occasion I venture a remark.

“I have seen this play.”

After a pause one of the company says, “You're keen.”

I explain that I went to a preview. Another silence then, “In one sentence, what's it about?”

“It's about Sharia law.”

Its constituent parts come in all sizes, tall and small, compact or full-bodied, and span the ages. But put them all together and an operatic chorus is a vast but single organism that sings – and moves – as one. The current Glyndebourne Chorus consists of 15 sopranos, 12 mezzos, 13 tenors and 18 basses. The longest-serving member has been singing with the Chorus for 18 years, but there is an annual intake from music colleges which will include several aspiring soloists.

A stage performance in any art form communicates through sound and motion. A photographer's task is to capture the dramatic experience in the silence and stillness of the 2D image. In the worlds of ballet and opera, none does it with more commitment to truth and drama than the great Laurie Lewis. To mark the end of the 2012-13 season, we present 25 images selected by the photographer exclusively for theartsdesk.

Bill Cooper photographed the Laurent Pelly production for The Royal Opera of Donizetti's La Fille du régiment, designed by Chantal Thomas and Laurent Pelly, conducted by Bruno Campanella, and starring Natalie Dessay and Juan Diego Flórez. Here is a selection of images, and you can read theartsdesk review here.

A new production by The Royal Opera of Tchaikovsky's The Tsarina's Slippers opens on Friday at Covent Garden, directed by Francesca Zambello, designed by Mikhail Mokrov and Tatiana Noginova, and with an all-Russian cast of principals conducted by Alexandr Polianichko.

English National Opera's new production of Bartók's Duke Bluebeard's Castle is photographed here by Johan Persson. Directed by Daniel Kramer, designed by Giles Cadle and lit by Peter Mumford, it updates Charles Perrault's 1697 fairytale to a horrific modern reality. Clive Bayley and Michaela Martens sing Duke Bluebeard and Judith. See Ismene Brown's review.
