One of the tourist attractions on the outskirts of Ponta Delgada is the Gruta do Carvao, which is an old lava tube. I found it quite interesting and a complete contrast to the many water made cave systems I’ve visited. This photo has been ‘recovered’ using some extensive photoshop manipulation – at the very moment I wanted to use the pop-up flash on my Canon 80D it decided it didn’t want to work. I tried in vain to find some obscure control in the menu system but with no luck. When we returned home I had to send my camera off to Canon for repair…. and of course it was out of warranty!
No worries (though of course the Canon being out of warranty was so) because the image looks suitably Hadean, as I’m sure it was intended to be!
