Vozhani village.

They are not from the same series, actually from two.
The first rime, f13, 1/13s, CPL+gradient grey:

Lead-like clouds, f13, 1/15s, CPL+gradient grey:

Vozhanskoye lake panorama, f13, 1/15s, CPL+gradient grey:

The village, f13, 1/13s, CPL+gradient grey:

The entire series was taken on the same day, even more to say, within half-an-hour.

The next image is earlier, dating back to 2016, f14, 1/80, CPL and possibly gradient grey, but I'm unsure.

Balamutovo village.

The railway embankment proved right what I need. That few is everything I could select from a pile of images taken in various conditions.

Looks like a combination of CPL and skylight, unsure though:

Not too successful example of the ND4 application in counterlight conditions:

An old photo, no filters at all, no .raw, just jpeg:

The valley view. In my opinion, it looks oversaturated, nonetheless, may it exist:

Came too late, from another spot – see here – the lighting was mediocre: 

Just jpeg, almost no way to edit:

...to continue.

One spot series once more.

It’s one of the very few places hereabouts suitable for the panoramic photography. Traditionally, represented as a series containing various conditions like seasons, time, weather. Unfortunately, thanks to a time gap between taking then and publication, I have totally forgot, what filters were used here. CPL is unchangeably used as a sine qua non everywhere, but the second one is alternate – as general, either gradient grey or skylight, more rarely gradient blue or orange. It’s typically possible to recognize a filter’s type, unless the image is not overprocessed. 

Winter morning, right before the moment of sunrise:

The first rays have arisen:

Filters, as far as I can guess, CPL+gradient grey, skylight also could be applied, less probable though. 

Belated spring (taken in April), colours of sunrise:

Cold summer (taken in June), the last sunrays:

The same with CPL+gradient blue filters: 

The first moment of night: 

Summer (don't be hoodwinked by yellowish shades  – the images were taken in June) shouldn't look like this:

The same picture a bit later:

Colours of eary autumn:

It would be logical to continue with some gloomy samples of autumnal landscape, but I have none to offer, except low quality ones, very difficult to process. 

Sunset over a gloomy landscape.

Actually, it’s an old example of a genre that I call “Infernal esthetics” – just my personal definition, I have no idea whether it’s current anywhere or not. Here we see the entire set of preconditions to fit the infernal esthetics concept’s frames: the cement factory (“Eurocement”), railway, cemetery between the author’s position and the factory, technological road and dull landscape. The series was taken in 2015, now I have edited it anew. The set looks like a desperate attempt to vivify a gloomy picture. Unfortunately, I neither used filters nor saved data in .nef, those are pure jpegs.

Geometry. 

Sosnovka village and "Eurocement":

Pastel-like colours. Facing towards “Eurocement”: 

The same view from a railway:

A-114 crossroad.

Nothing in it, in my opinion. Hope to take a better version.

Hot morning, Zinovya Gora.

Hot morning, Zinovya Gora. Aperture f16, shutter speed 1/10s, CPL filter. 6.20 local time.

Thunderstorm is approaching.
