In theory it should be very easy to capture an image of a celebrity but you encounter problems you don't expect. The person concerned was constantly surrounded by people and  getting a shot of her without other people in the frame was next to impossible. 

My solution was to take the best shot I could of her and then a seperate shot of the background afterwards. Once I downloaded the images it was an easy job to recomposite the celebrity into the new background by cutting her out of the original shot, blending her into the new background from the same photoshot. 

I then matched and harmonized the colours and created a new master. This was common practice for years in newspapers but a harder job to do and it was film cameras in those days so involved a lot of work which nowadays can be done in hours.
