Last new Photoshop technique

HDR-ish images!
in 8 easy steps:

[ 1 ] We'll call the original layer "ORIGINAL", now duplicate ORIGINAL and place it above that layer. (We'll call this "BLACKWHITE")

[ 2 ] Change the Blending option of BLACKWHITE to "Overlay"

[ 3 ] Go to Image > Adjustements > Desaturate (SHIFT + CTRL + U)

[ 4 ] Now invert BLACKWHITE: Image > Adjustements > Invert (CTRL + I)

[ 5 ] And add a gaussian Blur to it (Filter > Blur > Gaussian Blur) around 40 pixels (This causes the so called 'bleeding' of the edges, tweak the amount to personal likings)

[ 6 ] Now duplicate ORIGINAL and place it above BLACKWHITE, name this layer "LINEAR_LAYER"

[ 7 ] Change the blending type of LINEAR_LAYER to "Linear Light"

[ 8 ] Give LINEAR_LAYER an opacity around 62%. And you're done (For better results, tweak this percentage)
