Each week our chief photographer Anita Ross-Marshall picks her favourite shot from the archives. She writes:

It is the vast variety of people, events and dramas that make this job so different. No job is ever the same, no obstacle the same and no picture should ever be the same.

But, it is the choice of what, when and how that defines the photographer when taking an image.
