The Mall Galleries specialise in genre shows and the latest exhibition is all about portrait painters, using both classical and contemporary styles.
There are over 200 works by over 100 artists on display and most of the artwork is available to buy.
There is a large collection of formal portraits including members of parliament and the royal family - with a special selection of portraits of the Queen to mark her Jubilee year.
However, where this exhibition shines is when it breaks the mould, such as Daphne Todd's muti-layered canvases and David Sagerson's portrait that seems to be made of post-it notes.
The stand out of the show has to be Andrew Salgado's piece (pictured). The broad brush strokes are reminiscent of Freud and Cezanne and his painting has an energy and a unique colour palette that makes it stand apart from the rest of the exhibition.
The Royal Society of Portrait Painters annual exhibition is on display at the Mall Galleries until 18 May. Admission is £2.50, £1.50 for concessions.
