About this tutorial:
First let me say this is as simple as I can get this tutorial. I wanted it to be as simple as possible for someone who has never used layers in Photoshop or much less blended a photo. There was so much more I could have done in this tutorial, but that would have over complicated this for someone new to Photoshop. I will have more tutorials in time that go into layer blending much deeper. In addition, this simple layer blending technique I used here can also be used in other apps like GIMP, Paintshop Pro, Pixelmator and much more. So its not just limited to Photoshop.
This image used in this tutorial is a combination of two separate exposures. First exposure being slightly under exposed, then the second slightly over exposed. The first exposure was taken at ISO125, f/7.1 at 1/320sec, second was at ISO125, f/7.1 at 1/30sec. Both were taken on my Canon 70D and were at 34mm and hand held.
