I wanted to do this as an oil painting. The only adjustment I made to the original, aside from resizing and reducing pixels from 180 to 72, was to use a curve adjustment layer to brighten the lower left.
I then made an mv layer [merged visibles 1], duplicated it twice and applied filter>stylize>find edges to the topmost layer. I set that layer to 17% and merged it with the layer below. This brought out the lines in the trees, windows and vines.
I made another copy of mv1 [mv2] and painted over it with a soft pointillist brush--I believe it's called "large texture stroke." It's #54 in the wet media brush series. I used a blue but didn't keep track of the color or brush settings.
I set that layer to hard light at 100%. This left me with a pretty dark image and the paint I'd applied didn't really make the image look painted although I could see the strokes over it.
I needed more paint so I made another copy of the mv layer [mv3] and moved that to the top. I went over this with a denser pointillist-type brush. I used #5 in the same series, a "heavy stipple" brush and set it to hard light at 100%.
This combined with the preceding level really brought out the blue in the window but the image was very contrasty with an extremely dark lower right corner and a very bright upper right corner.
Thank goodness for the curve adjustment layer. Using that I was able to lighten the bottom left a good bit.
It still didn't really look much like a painting so I again duplicated the mv level and went over that with a brush that I’d swear is a wet media brush but I can't find it. It's got 4 "petals" over a sort of square piece. Sound familiar?
I set that layer to screen at 29% and decided to stop there.
I merged everything and added a canvas texture.
I wanted it framed a bit so I made a 2 px rectangle using the shapes tool. I don't know how to make a rectangle that isn't filled and I couldn't find it readily in PS help [so embarrassing] so I just made a white rectangle, selected it, contracted by 2 px and deleted the middle.
I then used the bevel/emboss tool set to inverted cone or whatever that is that makes it look like a cutout and messed with the options.
That was it.
