Re-filming

I am going to be re-filming a part of my short film on Thursday 8th March. It is the part where the main character is walking through the alleyway shortcut, and the abductor jumps out in front of her. The reason I have to re-film this part, is because it is simply too dark to see what is happening in this part of the film. I am going to ensure I do not leave it to get too late to film it, so it won't be too dark again. One risk of this though, is that the re-filming of this part may look lighter than the rest of the outside scenes, if this is so then I will possibly have to use lighting, as there are no street lights around because I am filming in an alleyway.
