I think the main thing that I apologize for relating to my photography is that I don't photograph people. I have been asked a couple of times to do events and I have always apologized and said "I don't do people".
Only real photographers do people and get paid for it. They have professional grade cameras and Speedlite flashes, lighting stands and backdrops. Their cameras even seem to make a "real photographer" click when they press the shutter release. They do lots of post processing, fixing every blemish, every smudge, and even whitening eyes and teeth.
I take pictures of nature, old buildings, candy and teacups. Things that don't move unless I move them. I don't get paid to do that. I have an upper end entry level DSLR, and a nice tripod. I don't have a Speedlite flash or any studio equipment.
The thing is, I don't care that I don't do people, that I don't get paid or that I don't have high end equipment. I don't do a lot of post processing, I prefer to get it as right as possible straight out of the camera. I am happy with my progress as a photographer and blogger. I do have to work on being comfortable saying that to other people when they ask what I do.
I know I have more to learn, but that's why I take classes and continue to push myself. It is all part of the Journey.
No more apologizing!
