7. Other. I've been doing this as a serious hobby for almost 20 years now. It's a huge part of my dental practice, which allows me buy a lot of very nice equipment that otherwise would be out of my reach as an after tax expense. I can use about 90% of my dental camera purchases on weekends for myself when I need to use high end equipment (and of course I'm responsible to the practice for it should I break the equipment) , and I use the office photostudio for family portraits and friends on weekends three or four times a year as well. There is also my personal camera gear that I can deduct a portion of for tax purposes because I use it 75% of the time at the office, but which I take home everyday for my own use and for which the office is not responsible if I break it. Unfortunately, most of my photography is dental at this time. I haven't had much time for any real creative vision based photography for myself even on weekends (last week's vacation pics notwithstanding), it's been all documentation driven photography (which unfortunately accounts for 95 out of every 100 shots I take). . That and the fact that my other hobby is competing for time with this old hobby. I do take a lot of photos of my kids, documenting their lives for posterity, but that's not quite the same as looking at the world through the viewfinder and creating the what our minds see through that viewfinder.Originally Posted by Copy_Kot
