UV-A and a bit of UV-B in Hawaii
The view from our flat east - this is the Mauna Loa.
The next photo is a sunscreen in UV-B.
Gear: GFX 50R mono, UV-Nikkor, UV-B Plus filter from uvroptics.com (https://www.uvroptics.com/index.php?UVBplus).
Got to the summit another day (3rd trial), alone, was at the top before the sunrise.
Temperature was +3 degrees Celsius (37 F) and the air pressure was 582 hPa.
Climbed to the actual summit 4207 masl.
I like how Mauna Kea casts shadow into the saddle between Mauna Kea and Mauna Loa - tens of miles away.
Those photos are from unconverted Fuji GFX 100s + GF 50/3.5 lens.
