Here’s the above image without processing in Lightroom:

As you can see it was a grey and dreary day. I tried to manage the exposure to make sure I kept some cloud detail in the highlights of this photo. However, this meant the foreground was a bit dark. It got even darker when I pulled back the Exposure to -1 to really get the sky to pop. So, I dialed in a big handful of Fill Light and a touch of Recovery. Finally, I tweaked the individual color Luminance sliders to get the blue sky and the yellow crane to really pop. I applied similar settings to the rest of the photos I took with varying results:

Unfortunately there was a locked fence around the facility which greatly limited my composition options. I’ll have to try again sometime when there is better light.
