I took my first spherical panorama in 2007 but didn't get fully into the hobby until a few years later.   Despite doing this for awhile, I'm still learning new techniques as I go.  I take photos of anything & everything, particularly of offbeat places only the locals would know about (or maybe not know about); my primary themes include:

 

Mountain summits (including gigapixels)

Lakes/waterfalls/bodies of water

Glacial geomorphology

Geology

Historical sites

Places of mystery/tragedy/crime

Caves/mines/tunnels

Aerials

Abandoned ruins/places in decay

Fire lookout towers

Cemeteries/specific graves/veteran memorials

Night scenes/cityscapes

Floral & botany

Trashed & destroyed vehicles

Art scenes/one-of-a-kinds

Anything of sentimental value

 

Photographing has always been my pictoral diary as one never knows when something is going to change.  Many of my adventures have been of solo exploration & I hope for many more.
