Yosemite Valley, July 2008. I take stereoscopic (3D) photo pairs. I use 2 cameras to shoot a left view and a right view simultaneously. Seeing scenery in full depth is so much more realistic and enjoyable. Most people, seeing a good 3D image for the first time, say "Wow, it's like I'm there!"
See if you can view this "parallel" pair in 3D! If you can make the left eye focus on the left image and the right eye see the right image, you will see it as a normal two-eyed person would see it... in true depth. It can take some practice... I learned to "freeview" 3D pairs like this by placing a long sheet of paper from my nose to the screen to act as a septum, forcing each eye to be able to see only its own view. As an alternative, one can obtain inexpensive viewers (like the Loreo Lite Viewer from loreo.com) for a couple dollars each.
My father took stereo photos with a Stereo Realist camera and slide film back in the '50s. I grew up enjoying those images, and now I make my own. I started with film, but lately I've switched to digital 8x10 prints viewed in a special viewing device.
For me, RVing is primarily a way to see and photograph the wonderful, diverse scenery this country has to offer.
