The sky is an integral part of just about any landscape photograph, and as such, it deserves a healthy dose of your attention during the editing process. If you would like to improve your landscape images, check out this excellent video tutorial that will show you three different ways to adjust the sky using Photoshop or Lightroom.
Coming to you from Matt Kloskowski, this great video tutorial discusses three different ways to adjust the sky of an image using Lightroom or Photoshop. If you have not tried out the automated sky masking tools in Lightroom yet, you are missing out. I have to admit that I have been mightily impressed, as it has been able to successfully select 99% of the skies I throw at it, even those shot through complex windows and trees. This has made it far easier for me to work with a lot of images and has made my editing process much more efficient, which is always appreciated. Be sure you aren't overlooking the panel. Check out the video above for the full rundown from Kloskowski.
