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

You would think that sunshine is the photographers best friend - but not always.

It makes colours come alive, people relax and the days seems longer.

But it also means that photographers have to get their flash units out.

We have to battle with shadows and use a system called “fill in”.

It is a process where light is used to enhance light and the results can be beautiful.
