Taking Photographs with Photographer

I am not very good at photography/ don't have a good enough camera for it so I decided to hire one of my friends to take photos for my project. I will be "matte painting" with these photos (chopping them up, putting them together etc to create a new scene). These photos won't be the same as before, if I left them the same I'd feel it wasn't my work. From there I will composite my models into the scene and I'm finished!

(These photos aren't by my photographer friend, but me documenting the event).
