Filters in Photoshop

I was playing around in photoshop the other day, testing different filters. 

I used a picture I took of Hallgrímskirkja at 101 Reykjavík on a beautiful&really cold day:

Before: 

 

cyan 70 saturation -100

deep emerald 70

deep emerald 70 saturation -100

red 35 - saturation -100

  

 red 50

 yellow 45, saturation -100

sepia 70

 

sepia 70 saturation -100

underwater 60

 

 warming filter 50

 

What a difference a photoshop-filter makes...
