Re: Single camera stereo ( where subject moves or camera slides)

I agree cross freeviewing is not easy for a portion of the population, and probably impossible for a small portion. I liken it to learning to ride a bicycle. It's hard (ouch) at first, but once you get it, it gets easier and easier.

I can also parallel freeview, but large images cause eye-divergence, which ALL the population finds uncomfortable. I can comfortably freeview Holmes cards at less than arms length.

Viewing has always been the downfall of stereophotography. All the parallel viewers you mention are great solutions, but IMO, a Realist Red Button (for 35mm) or a Keystone Visual Survey Telebinocular (for Holmes cards) are amongst the best viewers commonly manufactured. YMMV.

As to image element "z-axis placement" on the screen, it makes no difference if parallel or cross.

I WOULD suggest you purchase a cheap used "Windoz Box", JUST for SPM. I freeview the images (cross) on screen and make all common stereo adjustments (aligning, cropping, window setting, slight horizon leveling) in real time. BUT, there is a learning curve. It has LOTS of features, and accepts/ouputs just about all stereo formats ever devised, and is updated frequently.
