My second attempt....I love antiquing and mountains are a great subject for this style.
What I did:
-Cropped a bit off the bottom
-Desaturated and colorized sepia
-Adjusted histogram midtones (-14)
-Duplicated layer, applied gaussian blur and blended soft light at about 50%
-Merged all layers
-Duplicated layer again and painted in scratches...opacity 10%
-Merged all layers
-Duplicated layer, applied gaussian blur and blended overlay at about 50%
-Merged all layers
-Added noise
-Created a vignette with a mask, choosing a color from the photo (near black)
-Blurred the mask to better blend the vignette
-Added a thin black border and then a white border. Used the fill tool to change the black border to brown and it ended up filling in some other spots in the photo. Definitely not intentional, but I thought it added some 'antiquing' quality to the photo so I left it. To me it almost looks like the photo was burned or something...
-Painted over the brown border into the white border to make the border edge less defined
I definitely like this better than my first attempt, although I need to expand my horizons beyond 'antiquing' because I am using it a lot.
