This past week as the weather here in Oregon has become more consistently overcast and darker (as the days get shorter) I've started to get a few more of these images.
I'm trying to figure out what what's going on with these and I came up with a working hypothesis. Please feel free to comment and correct any inaccuracies in the following, which is conjecture.
Wiki says film Solarisation / Solarization is caused in the darkroom by exposing film to light. As a consequence of this exposure to light, "parts of the image reversed in tone but a thin line is generated around areas of contrasting tone."
Something similar happens in these Vistaquest VQ-1005 glitches, but it isn't a reversal in tone, but a super saturation in color that seems to take place. This is probably related to the saturation this model of vistaquest is noted for. The line referenced in the above quote seems to have an analog here as well, grouping colors together in large swaths. I've got a pretty good example of the edge detection that can occur with the vistaquest here
Solarisation is a big can of worms if you look at the various forms of film solarisation, photoshop solarisation, and in-camera digital effects. I was tempted to call what happened in my photos pseudo-solarization, but it seems from the wiki, that that term is already taken, so I'll call it Vistaquest Solarisation for the time being.
An example is listed here and here of an early digicam, the Mavica, which included a solarisation effect. I'll try to dig up some more examples and edit this post as appropriate.
