The floorboards creak and squeak underfoot and the room echoes to conversations about David Bowie and the images presented on the panels in an upstairs floor of Dublin's Rathfarnham Castle.

This is A Portrait in Flesh, a photographic exhibition by David Bowie's favourite photographer, Denis O'Regan. 

Denis photographed Bowie at more than 200 concerts but also captured many candid scenes on travels with the music legend.

After an extensive look at the various concert scenes and the behind the scenes in black and white and colour, I chat for a time with Denis.

He tells story after story and we chat about various topics photographic from camera bags to digital vs. film photography as well as anecdotes from his time touring with and photographing numerous rock bands including Thin Lizzy and Duran Duran.

A favourite of mine comes from Bangkok 1983 and it features Bowie brandishing a guitar, wearing a cyan blue suit, his left leg aloft and the top of the guitar out of frame. There's a whole load of empty space but his raised left foot and sock matches his guitar and right shirt cuff. We see enough of his face to know it's Bowie, an image full of energy.

But there's something special about the images of Bowie relaxing in boats, walking through a flooded Bangkok showcasing O'Regan's travel documentary style and the Bowie's innate ease in front of the camera.

The exhibition ends on the 11th of February so get a move on to see it or else why not pop into O'Regan's gallery in London at 271 King Street, W6 9QF where his images of many of the 20th century's (and 21st's) greatest musicians are on display from Phil Lynott, Bob Marley, Mick Jagger, The Who, Marillion etc. to Amy Winehouse and Beyoncé.
