Simple really - What knocks your confidence with regards your photography? Or are you lucky and you're bullet proof? Or do you not care?
Interested to hear your thoughts.
It helps if you don't care too much, don't take yourself too seriously. Don't expect too much - magic just doesn't always happen every time you pick up a camera, same as with any other creative/artistic endeavour. Worthwhile images always have a lot of effort invested in them, one way or another.
And certainly don't expect anything of others. Why should they care? That way you won't be disappointed
For most people, photography is light hearted, fun, and disposable. It is generally easy and therefore has a low 'value.'
Pictures of gurning babies mean the world to the parents, and nothing to anybody else. (Pictures of cats often fall into the same category.) Most photographs are 'personal' in that sense, and simply don't have any wider significance or appeal.
If an image doesn't relate to you emotionally in some way, you cannot respond to it. When pressed, people then tend to fall back on technical criticism of exposure/focus/composition when what they really mean is 'I don't give a damn.' And frankly, why should they? How to you respond to other people's everyday snaps? Don't try and read artificail significance into them, that's phoney. Real quality shines out.
If your photography is more recording than creating, then prepare for a low hit rate. Even the greatest photographers cannot go out and bag a load of great images at the drop of a hat. It doesn't happen.
But what you will find, without fail, is that those folks who consistently post great images have put in a huge amount of time and effort getting them. Good photography was never easy, and despite amazing technology today, it still isn't. The great landscaper Ansel Adams, who was largely at the mercy of nature and the elements reckoned than 12 keepers a year was a very good score! And he was at it every day.
If you are more into creating stuff - maybe portraits, still life, unusual technqhues etc - basically stuff that does not present a great image without you doing something to change it, you have a better chance (but fewer excuses).
I'm lucky in that photography operates on three levels. Of course, taking great pictures is the biggest buzz, but I also enjoy employing skill/knowledge/craftsmanship in a creative way, just for the sake of it. Satisfaction of a job well done and all that. And then I also like the kit - I'm a bit of a gear head! I also enjoy reading and writing stuff on here. All part of the fun. So that's four enjoyable aspects!
