A few weeks ago I took a bad picture and I knew it when I took it. I also knew that I could fix it. Below is a quick video on how you fix blurry photos using Photoshop CC shake reduction tool. Once you play with a the tool a few times you will get the hang of it. Warning though, it does much better with daytime pictures where there is a lot of light.
I played around with more settings than I needed to but the picture came out all right for a demo.
