We're Cameramen/camerawomen!
I've been shooting & editing for 24 years. I frequently do my own interviews...and even write anchor-track pkg's. I can edit on 4 different NLE's.
But when someone on the street asks what I do for a living, I tell them "I'm a TV news cameraman." Joe Schmoe can't tell the difference/couldn't care less about the "photojournalist" or "videographer" label. All he or she knows is that I work for some local TV station and that I have a camera. I've won awards for shooting, editing...and even writing (a feature pkg that I shot & edited.) So I know what I'm talking about.
And...I don't have any delusions about who I am or what I do.
Photojournalist/videographer/video journalist sounds like a bunch of snobbery to me. It sounds like what guys tell the chicks at bars or parties to impress them...or, as in the original poster's case, what one of us would tell a class full of impressionable young kids. It's kinda like the interns at our station who go out on stories with us to hold the mic and ask a question or two at pressers: When asked what or who they are they always reply, "I'm a field producer." Naaah...you're just an intern!
Outside of our profession, NOBODY knows what a photojournalist/photog/videographer is. Tell them you're a photojournalist or news photog, and they'll ask you "What paper do you work for?" Tell them you're a videographer, and they ask you "Do you do weddings or Bar Mitzvahs?"
I tell people I'm a TV news cameraman. It is THE BEST, most descriptive description of what we do. Tell them this, and Joe/Suzy Public automatically know what it is we do for a living.
Save all that photojournalist/videographer/news photog garbage for the NPPA Seminars/Unity Convention and other professional get-togethers that we as TV NEWS CAMERAMEN/WOMEN attend...for these are the only places where the people will "buy" what we tell them.
