photoshop

This effect was created the sharpen and blur tool.
The mountains at the very back were blurred by 85% then the slightly closer mountains by 50% then finally the closest ones behind the church i blurred by 20%
I sharpened the church by 205 and finally blurred in front of the church by 50%
All of this has enabled me to create the church in focus and the rest of the picture to be out of focus.
