toni-a, I know you started the thread and contributed some pretty funny experiences (at least, after some time we should be able to laugh at our mistakes). It just could look like, that if 6 of 16 posts are from you, you're kind of photographing with no lens in front of the camera - and I'm pretty sure this would be the wrong impression.
How about of giving advice to dumb photographers by writing the moments, when looking back and feeling pretty clever by making the best out of a potentially catastrophic situation? I'm afraid, we don't learn a lot out of our or others mistakes, otherwise we could just stop making them.
Sometimes I was not telling the person in front of me that I was taking pictures with wrong exposure and/or AF-setting. The situation was still there and gave me - funny enough - courage to ask for some pictures twice in a way that I wanted to have a better photo. It depends, of course: Admitting my failures could relax the model ("he's only a man and also struggling with gear...") or make him/her thinking of "this guy is wasting my time with his dumbness".
Next to it and not meant as an excuse: We have to look at quite a lot of menu crap, button desasters and energy solutions which make us helpless, sometimes on purpose of the manufacturers as well. Yes, I could have thought about spare batteries or closing the zipper of my slingshot-bag before I saw a camera on short air-travelling towards a marble floor. But we should be aware, our misfortune sometimes has many fathers:
- Which camera let me take AA-batteries instead of proprietary ones? Except some Pentax models?
- Which cameras let me charge the batterie with USB? Except Sony?
- Which camera has a really foolproof menu? Except the analogue ones without any menu?
- Which bag has not to be opened occasionally?
Of course, we choose what we use, so again, our mistake?
