I'm just back from a snowboarding holiday in Austria. My traveling companions took many photos and had fancy cameras, whereas I took only a handful and have never owned a dedicated camera – using only my mobile phone on occasion (which does take a reasonable 5mpix picture if conditions are right).
I am not sentimental, and the photos I take tend to either be artistically pleasing or purely to put on facebook to placate family that protest if I don't. That means that the photos I take are either of people (this seems to be what others want to see photos of) or desolate vistas – one of the reasons I enjoy snowboarding is that, if visibility is good, from the top of a mountain in the Alps you can see giant snowy peaks stretching out into the distance.
Mountains and clouds and big rocks and starry skies are the scenery that impresses me most; I find it kind of liberating to feel how small and temporally fleeting I am. Some may find that feeling depressing, but it isn't simply that I feel I am small and ephemeral, I feel how insignificant everything in life is – everything in everyone's life – and that makes me feel powerful because I know that most people get caught up in their mundane existences and never realise their true place in the world. It reminds me that I am different to other people; and by 'different' I mean 'better'.
