I consider myself an advanced amateur. I only consider a person a pro if he/she makes their living from it. That is my definition and I am sticking to it.
I was raised around cameras as my father loved to take photos. I learned from him on his Kodak Retinette 1A range finder. I used the Kodak throughout my elementary school years. When most kids were playing with legos, I was outside with a hand held light meter and a camera. Yes, I was a strange kid in retrospect lol (I still have the camera).
My first SLR was an Olympus OM10. This was in my grade 9 year. I used it for several years until I took a photography course at the High School. On my first day, I saw another student with a Minolta Maxxum 7000. I fell instantly in love with the AF feature. I quickly did some homework and bought my first Pentax, the SF10. That would be around 1988-9. Around the same time, I built a basement darkroom. I sort of had darkroom acquisition addiction for a time. I dare say I had more enlargers then the school did, as a lot of people were ditching their darkroom gear at around that time.
I have been in digital as soon as it became semi affordable. My first Digital camera was an Olympus Camedia D320L back in 97-8. I then spent way too much on a Nikon Coolpix 990 in 2000. When I saw Canon produce the Digital Rebel SLR, I bought one because the price was affordable, and I so wanted a DSLR. I then moved on to my 20D when it first came out. I haven't seen the need to upgrade the camera yet, as it does everything I need. I bought my father a K10D, as he enjoyed his P3 for ages, but I later inherited all his photo gear due to his declining health. He just can't go out much and take photos. So I now use both cameras. I also own a Sony H5 for those times when lugging a DSLR just won’t do.
I have taught photography at the High School level for a period of 4 years until declining school enrolment and the cost of the program ensured it would get axed. I am still the school's primary photographer, and am busy taking photos for yearbook and other events. I use my work to justify equipment purchases (don't do this folks, it will just fuel any addictions associated with photography..although I consider my LBA well in check). I have also shot 4-5 wedding for pay...and swore to never do THAT again.
