For me, the introduction of photography was quite by chance, has it helped me, yes on many levels. My girlfriend is an artist, she specializes in high realism paintings and drawings. She used to work on pieces at home all the time, she does not so much any more as she works with special needs people teaching art. She was working on a piece at home, a huge sectional piece, that she wanted to take some pictures of for her portfolio. She asked me if i would use her camera and take the pictures while she held and moved it. I said sure, as i was doing so, i instinctively was looking for the right angles and light to bring out her piece, she observed this, and told me i should think about trying photography, basically nudging me.. So i did for awhile, but soon became frustrated with the cheap bridge camera i was using. I am an outdoor person, hiking and camping being among my favorite activities along with watching wildlife. While trying to shoot with this cheap camera, i found the autofocus just could not keep up with the subjects i want to shoot "hence the frustration". So i put it down for a while.
Months later my 14 year old son, had a sudden asthma attack, that took his life. I went into a depression and did not want to do anything for the longest time. My girlfriend was worried about me, and decided to give me a gentle nudge again. She got me a new camera with the lens set.. I am now getting out more again, and into nature, where i am feeling a little more whole again.
So for me, like Rick58 , it is a form of therapy. It has brought me most of the way back, from a place i did not think i would return from. Even though i am a amateur with a long way to go in the learning department, i enjoy it, and dedicate my better shots in a folder for my son..
