A Photoshop Layers Breakthrough

I had a breakthrough tonight that I just had to share.

few weeks ago I took the plunge and downloaded Photoshop. I'd never used it before. It is overwhelming. But I felt like it's was an essential part of any serious photographer's workflow so I needed to learn it. To fix ghosting in some of my amateur HDR photography I had to passably master Layers. 

Layers, for those of you that don't know, and that included me a few weeks ago, is a great tool in Photoshop that allows you to pull in multiple photos and use component parts of different exposures. For instance you might want to lighten the sky using the sky from a brighter exposure. 

had the hardest time trying to figure out which 'layer' I was working with and which 'layer' I was attempting to pull in. I was ready to throw my computer through the wall when I had a breakthrough. I finally realized that the main layer was, of course, sitting on top but the layer I was pulling in is simply one below the top layer. It's that simple and no amount of searching on Google helped me figure that out.
