Editing Steps :
---------------
1) I like to crop first
2) I found the pattern of circles and lines very interesting in the picture, so tried cropping to get the best effect.
3) Also inverted the image to bring out the element of mystery to the image
4) Channel Mixer
5) Tint
6) Dodge and burn the hell out of the image to get the grunge effect!
7) Resize for web and add border
I hope I do not offend anyone by editing the hell out of the pictures, I am just having too much fun, I am never able to do this for challenges as I am always too conservative on editing!
