I really like this one in b+w because it has a different mood than the colour version. Maybe I'll post the colour version later but this one almost demanded to be converted into a monochrome pic!

ABOUT RAINTINGS
Rainting is a word I coined describing a painterly effect, achieved by photographing the subject through glass that is being rained on, like a windshield or other. It achieves an oftentimes pretty or soft flowing effect, and sometimes other-worldly. It is usually creative, fun, and fluid, seldom harsh in my opinion. I have an album of them on Flickr. Rainting is already in "The Urban Dictionary" but I would like it to also be in a more sophisticated/educational type of dictionary. I started a public Flickr group of Raintings on New Year's Day 2020.
The more collegiate type of dictionaries say that the word has to actually be used by people before they're likely to publish it. So if you like the word and my idea, say it loud and say it clear and take a few Raintings and post them to my new group. Using my word and trying my new group are not inclusive of one another.
******************************************************************
This particular image has what I call a Faux Rainting effect. It wasn't actually raining; just a spray bottle of water on my truck window. I'll put it in my new Raintings group, but eventually I'll try to label the ones that didn't actually use *real* rain. The majority will be real rain, as that is what I used to take my beginning "Raintings" when hadn't yet thought of a name for what I described above. And that is why I rhymed my word of Rainting with Painting. My State of Oregon USA is known for lots of rain; so I shouldn't have to resort to Faux Rainting too often (grin).
******************************************************************
ABOUT LIGHTLINGS
Lightling is an even newer word I coined to name the odd little sort of anthropomorphic characters that sometimes appear in my images when doing a Rainting. They come in many sizes, shapes and colors and often times have what appear to be various facial expressions. In school we may have learned that a square is a rectangle, but a rectangle is not a square. Well Raintings can exist without Lightlings in the scene, but Lightlings cannot exist without a Rainting.

A pool side view of the sinking hotel. I find an irony of a getaway island and abandoned structures.
Rotated to a Nikon F with 50mm f1.2 lens - unusual for me since I 'see' more wide angle then conventional - weird that way. But I think I must've mixed my Xtol wrong, as I had some challenges with grain and development. But overall the exercise with a 'normal' view was a good one. I continue to thank the flickeranians who inspire all of us to keep making the images - practice x a million.

Elfrida, Arizona (population 459).
Elfrida's less than thirty miles from the US-Mexico border. Stopped here for lunch on the way back to Tucson from Whitewater Draw. (The Sundown Steakhouse was pretty good.)
Uptown, downtown, entering and leaving... much of Elfrida is seen here. Truly a taste of small-town America.

I've been surprised sometimes at how inclusive various leaders have been in history. In these stone churches in Lalibela one can see crosses from many parts of the world, including India, and also David's star. Inside one of the buildings in Agra one can find similar inclusiveness, symbols depicting different faiths.
