Press Association photographer Niall Carson returns for the final part in his mini series to talk about the excitement and enjoyment the job still brings him, despite being shot, bombed, punched and arrested! It seems it's all in a day's work. He also talks about the mental health pressures of photojournalism, his favourite news photograph and a forthcoming book.

Today's show is kindly supported by MPB, trading thousands of cameras and lenses every week across Europe and the US.
