Hi all! A friend of mines brother is a singer and he is shooting a video clip for his new song. I was offerd to take still photography on the set, this comming saturday. Now, of course i jumped at the opportunity, concidering i havnt had too much (or any at all) experience. Only problem is, i dont know if i have the right equipment. I'm not going to charge anything of course. But i still want to do a good job. Any tips or ideas i should know of?? I have a nikon d90 with a 18-55mm & 55-200 lens' Im not sure which of these to use, i have no flash or anything.. any suggestions would be a really great help.
