Create Grid Overlay in Photoshop | Plus Bonus Tutorial

In this tutorial we cover how to show grid overlay in Photoshop. I also included a BONUS tutorial. Would you like to keep your grid lines when you make a JPG of your work? It might surprise you that Photoshop does not transfer your grid overlay lines when you save your work to a JPG image. In the BONUS tutorial I will show you a shortcut that will save your overlay grid to a JPG.
Note: I am using a new computer and new dual monitors. For some reason, at times, my screen capture program did not include the highest Photoshop menu. I will have a solution in my next YT tutorial.
