The first major retrospective of the videos, photographs and sculptures of Gillian Wearing is a deeply disturbing experience. Her videos can be just a few minutes, or as long as an hour, but are not sequential narratives. They can be dipped in and out of - unlike many video artists you do not have to acquiesce to her time scale. But take a lot of time: they are more than worth it, and repay repeated viewings.

Royal families and royal academies. Aristocrats at ease in exquisitely landscaped gardens or inside in gorgeous drawings rooms. Actors emoting, notably Sir David Garrick and his troupe. Nabobs in India. All are depicted in Johan Zoffany’s rivetingly detailed paintings of Georgian society.

He was uncompromising, honest, personal. He didn't like doing what he was told. He never followed fashion. Is this an accurate picture of Lucian Freud, or is it a description of almost every great artist who ever lived? The intensely banal voiceover for Lucian Freud: Painted Life on BBC Two which contained these insights (at least in the rough cut I viewed) made it seem like a painter out on his own, stringent in his artistic pursuit, was something we had never seen before. Thankfully the talking heads, intimates of Freud, created a properly personal portrait.

Sitting for Lucian Freud was quite a commitment. Unlike Hockney, whom he painted and who painted him, Freud was a very slow painter and he was methodical. Paying close attention to detail and absorbed by different textures, he was intent on building up surfaces meticulously, layer upon layer. This meant that sessions would usually go on for several months, sometimes years.

Pallant House in Chichester has just inaugurated the series of Lucian Freud exhibitions this season which have have now become memorial commemorations since the artist’s death last July.  Freud’s life and studio have taken on a mythic quality, here reinforced by the photographs taken by his long-term studio assistant, David Dawson (see gallery below).

In one small room of the Freud Museum, which was once the home of Sigmund in the last year of his life, are the works Jane McAdam Freud made in the final months of her father’s life. Below an imposing photograph of Freud the elder, the progenitor of the clan, are two detailed, tender sketches of Lucian in profile. In the right sketch the dying artist stares resolutely ahead, his gaze, coupled with the firm set of his jaw, capturing a sense of absolute stillness. The left sketch shows the artist now more gaunt, eyes closed, in death, we imagine, or possibly just asleep.  

The Scottish National Portrait Gallery has been transformed with a £7.6 million facelift. As a first-timer I confess I don’t have a clue what it looked like before, but I am assured it was dark and gloomy and had the air of a building cast aside in favour of Edinburgh’s better attractions.

Before the internet and the Kindle were invented, generations of Americans saw their lives refracted through the pages of Life magazine. In particular, through its photography, since writers at Life were largely relegated to supplying glorified picture captions. They were also allowed to carry the photographers' equipment.

Dogs, horses, cows, sheep, goats and pigs are the creatures that, however minuscule in stature, take pride of place in the fascinating exhibition of Thomas Gainsborough’s imaginary landscapes at the Holburne in Bath, an ideal complement to the nine major Gainsborough portraits in their British picture gallery.

Surprisingly for one of the most prominent portrait-painters in all of British art, Gainsborough's animals, lovingly portrayed, their body language based on acute observation, dominate their human counterparts in these landscapes, who are more or less rural stereotypes.

From Edinburgh to London and back, via Tatooine and Port Talbot, Rich Hardcastle has photographed playwrights and magicians, burlesque dancers and rugby captains, and regularly adorned the covers of The Big Issue, FHM and The Sunday Times Culture section. Along the way, though, the 40-year-old Londoner has missed no opportunity to shoot the great and the good-humoured, has documented Karl Pilkington’s idiocy abroad, and has produced the pictures for the illustrated book of Extras.
