It took me a while to get to Yellowstone, and I can't really explain why, for I'd photographed in most of the other major Parks in western USA some years ago.  But I did manage to put that right in late September 2012,  spending a week or so inside the park as well as some time in the Grand Tetons and Montana.  We stayed in the Park Lodges, so had no excuse not to be out and about in the right places whenever the light was worthwhile.

My major objective was to photograph Yellowstone's thermal features- the pools. geysers, the colourful run-offs and the steam.  I did some landscape work too, both in the Park and also before and after in the Grand Tetons and Montana, but to my mind at least this ran a distant second to the thermal activity and its fair to say that i might not have travelled 5000 plus miles for the landscape opportunities alone.  Meanwhile the thermal features were absorbing and varied.  I hadn't realised how different things might look under heavy steam in the early mornings and under bright or overcast skies later in the day.  So each of the areas merited and got several  sessions.  Yellowstone might have been a long while coming for me, but it certainly felt worth it in the end.
