From the Karl Taylor YouTube Channel:
Make your Sky Outstanding with this Top Photographer Trick! – What I’m going to show you today is how you can enhance the sky in some of your photos. So if you’ve ever taken a shot but feel the sky needs a lift then this knowledge is for you.
I’m using Photoshop and you can apply this technique to any of your photos. You’ll probably find that other photo editing software enables you to use the same techniques.
The Creative Cloud Photography Plan (Photoshop CC & Lightroom CC) is an excellent value at only $ 9.99/mo.
