Shooting problems

We have had some problems with lighting in our video, during some of the internal shots the lighting was poor. This can be seen during the shot where the girl is seen drinking tea and then it goes into it's own cup, this was difficult to correct using the editing software that is available to us. The way we are going to over come this is by reshooting this particular shot with a stronger lights against her, we have a flood light available to us which we could point away from the shot against a piece of large white paper to give the illusion of natural light against her. Doing this will improve the quality of the shot.
