Being the last year as undergraduates, my class and I want to do a graduation class photo (something like this).
Even if I know the something of photography, I'm not professional (and I don't have pro equipment or good flashes of any kind). We are also considering hiring a professional photographer but I haven't had good experiences with studios in my area.
What I am asking is: what should I consider when looking for a photographer for this? (maybe equipment, what kind of events they use to cover...?) and, if I do it myself, what should I take in mind? (perhaps illumination, use some filter, try to get some good flash, post-process...?)
The design of the composition is not a problem, just photos themselves.
(I know it's two questions, but I think they are too related to separate them in two different questions)
Thank you for your comments.
