There's the separation of terms Photographer and Professional Photographer... While most anyone with a camera and an understanding how to use it and to do so in a way to create images is/could be considered a Photographer, but most Professional Photographers do so for the sake of compensation whether it be money/barter/accolades, etc... The problem is most people blur the lines which is why most photographers will admit their greatest competition is amateur photographers... Professional photographers try to set their quality and price bracket at the next tier above but then again when a couple to get some joe blow off the street, pay him $100-150 to shoot an hour or two of their wedding and provide a CD of the images, hell yeah, that would be an easier sell than a pro to shoot it for $1500-3000 and get an album and handful of pictures... As for the OP, sure, call yourself a photographer but make sure if there is any confusion that you are not professional, unless you get to the point where you wish to become professional and developed a portfolio.
When someone who takes photos for a hobby refers to themselves as a photographer I don't mind so much, but then if they start to claim they are a "pro" after making a semi-decent portfolio and then undercharging to get some jobs that takes work away from people who make a living from photography I am not happy
This month I have lost out on two wedding jobs because of people like this. One was an email to the effect of "we'd really like you to take our photos, but we found another guy who will shoot all day for 100 dollars, so if you would drop you rate somewhat, say to 400 dollars (my minimum for a basic package is about 1200) we'd be willing to hire you." Errrm, no.
