Test shots.

I had to mess around with the lighting to get it right so that there was enough light but not too much artifical light from different areas of the room.

This lighting would have been ok because it didn't create too much of a shadow however Molly and Katie's hair would have faded into the background because it so light.

This lighting was too bright which made the subject too pale and their skin faded into the background.

This lighting worked well because the flash wasn't too bright so that it made the subject really white and the skin tone colour looks really natural.

This one was using the flash without any other light sources in the room which I think worked the best. As it didn't create too much of a shadow to the side of the subject and the subject stands out from the background.
