Thanks, tn.
Quick thinking? More like quick return to thinking.
It was the very brief nature of the exposure that I thought might be of interest to people, but there's nothing new under the sun.
I've never considered cross processing, and I'm only vaguely familiar with it. That's using E6 chemistry on C41 or vice versa, right? I'll search for some examples.
I do like the effect, but with the caveat that I don't think it would work (or if the gradations in color are even possible) if it were affecting the whole image. In this case it's just enough to grab your attention and, luckily, it's placed in the sky just right to add a sci-fi-esque narrative flourish. Of course, it's unpredictable. Some other frames on the roll were unaffected, while the ones on the affected side of the spool had varying degrees of "pleasingness." One of them just had a nasty murky green fog creeping in from the corner (I hope I'm not making it sound cool, because it's not).
