My first go at HDR: 3 pictures shot at 100ISO and long exposure times, plus and minus 2 EV, 13sec, 2.5sec,30sec). It's reindeer lichen, a very slow growing lichen eaten by mainly Reindeer/Caribou.
This lichen I found while hiking up in Norway with my wife. It is highly protected and it is absolutely forbidden to break off. This loose piece photographed here I found on the ground in a swamp, it was partially eaten. I did not have to break it off, only pick it up, so I was kinda in the clear.
I did not know the reason for it having such a protected state. Years later I read about their very very slow growth rate.
Reindeer lichen is slow growing (only 3–5 mm per year) and may take decades to return once overgrazed, burned, trampled, or otherwise consumed. This piece is about 4cm in radius, so about 10 years old. I did not know that..
This piece is about 10 years in my possession now, residing in one of our book shelves. It is battered a bit, discoloured too. I'll have to make due.
