A day's walking in the Mourne Mountains today with some friends . On the way out I noticed a rock which I had photographed before (on 30 December 2010) and I decided to take another. The thing which caught my eye from a distance is the patch of white lichen which stands out very starkly against the rest of the rock.
It's interesting to compare the different treatments a year apart - 2010 is a bit underexposed to preserve the detail in the mist on the background. Both shot with a Canon G10.
