‘Here am I, at nearly 77, about to embark on a totally new technical journey,' the famed war photographer tells Canon Europe.
McCullin - who says he has printed all his own pictures in a career spanning more than 50 years - is seen using a Canon EOS 5D Mark III in the South of France, under guidance from documentary wedding photographer Jeff Ascough.
‘I'm not good at technical things - I have my limits but I'm willing to learn,' McCullin adds in the 27-minute video, called Seeking The Light.
Meanwhile, next month McCullin is due to appear on Sky Arts in a television interview with Sir Michael Parkinson.
A spokesman for Sky Arts said: ‘Talking through some of his most iconic works to date, the photographer opens up to Sir Michael about capturing images in warzones and the physical and psychological strain he's suffered for his art.'
The interview, which is due to be broadcast on 4 December, is part of a series called Parkinson: Masterclass.
