Hey guys I've got an opportunity to take some portraits for a coworker/friend. Her son has Leukemia and is going through chemo right now but has a week off and she'd like to get some pictures taken of him and his sister/cousins to give as a gift to the childrens grandpa. So she asked me to help. Anyhow, I'm thinking of doing it this Sunday before he has to go back in for another two weeks. My problem is that all I have is a D50 w/ kit 18-55mm lens, 50mm 1.4 and 70-300 lens. Which of those would be best for an outdoor portrait setting? Also, I do not own a flash at all so I'll be using the sun as my only light. Would you guys suggest I purchase some sort of reflector to bounce the sun a bit? If so, where would you place the subjects and reflector in regards to the sun? Thanks for any information you can offer. I hope to take some great shots to provide this family during this rough time in their life. Also Moderators, if this is the wrong forum to post this in please feel free to move it. =] edit: forgot to mention, I may be able to borrow an sb600 from a friend for the weekend.
