I don't consider myself a landscape photographer at all, but over the past couple of years I've been taking a lot more landscape shots. Both locations are places I have known for many years - in one case the area where I spent the second part of my childhood, and I've been visiting ever since, the other an area I have been visiting for over 20 years. I can't really imagine taking or wishing to take pictures of landscapes of places I've never visited before or don't know intimately.
I suppose the pictures I take are about me, or my relationship with the place as much as anything, it's not that I actively choose to work like this, I just don't or couldn't do it any other way.
There is also a place, (i.e.house an garden) rather than a landscape, that I've been actively documenting over the past 4 years or so.
I never run out of pictures to take, or get bored - I have many shots over many seasons, one day I'll sort them out.
I don't know the ethics and values of this, it might be that I'm self-obsessed, or things have to come from within myself as much as what's 'out there', but I can't help that either...
