What fun! Thanks for sharing!
I think the major strengths of Keith Carter's images (the swampy ones) are subject, lighting, and composition. I am guessing the images might be equally powerful - possibly more so - if presented more traditionally(?)
I do enjoy looking at pictoralist-style work. But the subjects and compositions of Carter's swamp photos are so strong, I would like to pull back the veil and see them a little more clearly. (But, perhaps if viewing the prints in real life, at actual size, the subjects would appear more clarity?)
A little research (not much) did not reveal anything about what methods Carter used to make the Ghostlight images. It shouldn't matter, but...
When I see a modern photo that has a distressed or historical look, sometimes I feel like the photographer is trying too hard. Trying to make the print somehow more "arty" by use of special effects. It's similar to how I feel when I see a digital photo with grain, dust, and scratches added in post-processing -- it seems like an affectation.
But here is the funny thing. If I know beforehand that what I am calling "the distressed or historical look" is a necessary and unavoidable result of the photographer working with some arcane alternative process, then I'm fine with that. Only if I suspect the photographer has taken a technically proficient negative and manipulated it to look artificially historical does it sometimes irritate me. It's like listening to music. If a vinyl LP has a few pops and crackles, I can tolerate that as part of the analog experience. But the same noise would be intolerable on a CD recording.
Silly, I know. I should be able to like (or not like) a photograph based only on what I see, and not on what I know. But every photograph is viewed through the prejudices of the viewer (and yes, I have a few).
