This show of work by two artists who use photography to explore the complexities of their own identity has to be the most interesting exhibition ever staged at the National Portrait Gallery, and opening in the same week as International Women's Day couldn't be more fitting.

Before we consign this miserable year to history, there are a few good bits to be salvaged; in fact, for the visual arts 2016 has been marked by renewal and regeneration, with a clutch of newish museum directors getting into their stride, and spectacular events like Lumiere London, and London’s Burning bringing light in dark times.

It’s that time of year again. The National Portrait Gallery exhibits the finalists in the annual Taylor Wessing Portrait prize. The judges have seen 4,303 photographs from 1,842 photographers and now show us 57.

There’s something familiar about those dark, piercing eyes, but the impenetrable, mask-like countenance of Picasso’s Self-Portrait with Palette, 1906, is ultimately unknowable. In fact, the painting serves as something of a rebuke: we think we know Picasso so well, but we don’t. It’s a theme emphasised by the hang of this exhibition, and the bewildering range of styles and formats from Picasso’s early years results in a visual discord that underlines his chameleon-like tendencies.

American photographer William Eggleston is famous for dedicating himself to colour photography at a time when it was still considered kitsch – acceptable for wedding and Christening photos, but not much else. The best known example of his embrace of colour is a 1973 photo of a red light bulb hanging from a red ceiling, a picture devoid of subject matter beyond redness and the associations it triggers.

A good half of the portraits in Russia and the Arts are of figures without whom any conception of 19th century European culture would be incomplete. A felicitous subtitle, “The Age of Tolstoy and Tchaikovsky”, provides a natural, even easy point of orientation for those approaching Russian culture, and with it the country’s history and character, without particular advance knowledge.

When it got too hard to ship the original American edition across the Atlantic during the Great War, British Vogue appeared as a sister publication in the Condé Nast empire.

Ever since Diaghilev’s day the relationship of dance movement to its visual design has been a lively, sometimes combative affair. Sometimes people leave whistling the set, saying shame about the dance; other times they hate the set, love the dance. As with the relationship of dance to music, the fit of look to movement can be decisive in why a new ballet escapes the curse of ephemerality and becomes a firm memory that people wish to revisit. It directs the audience how to read it.

At first glance David Stewart’s Five Girls 2014, the winning entry in this year’s Taylor Wessing Photographic Portrait Prize, is a very ordinary scene. Five young women sit behind a table, obligatory mobile phones within reach and lying amongst the remains of a rather dismal-looking lunch. They’re not looking at each other, and nor are they looking at us – in fact they are not even looking at the same thing: they embody the disengagement we like to insist is the malaise of the young.

This was the fifth and last in a series of hour-long programmes amounting to a vivid, varied and extraordinarily lively history of Britain. Although ostensibly a history of portraiture, the images have been hooks for Simon Schama, that most ubiquitous historian who bears a rather charming resemblance to Tigger – very bouncy, very chatty, very enthusiastic, a little self-regarding – to subtly engage us in a journey through the political and social landmarks of British history.
