Each week, the BFP’s chief photographer Anita Ross Marshall chooses some of her favourite pictures from the archive and give an insight into capturing the perfect image.

Some jobs on the surface can appear to be slightly daunting.

Pressure to get the best shots at the right time and place can sometimes get in the way of images that normally you would achieve with ease.

The key is to shut out all the outside forces and concentrate only on what matters - what is going on in your view finder in the camera - because ultimately that is all that matters.
