Super Simple Tilt Shift Effect in Photoshop - New or Improved Skill Day 14

I had no idea this was so easy to do and it's a bit of a mind bender. I got the tutorial from WeGraphics. It would be fun to lower the saturation for more of a vintage 3D effect.

My notes:
Command j to duplicate layer
Filter > Blur > Gaussian Blur. Radius 10 pixels.
To create the tilt shift effect you need to remove the fuzzy pixels. With the blurred layer selected, click on the layer mask icon, it's the rectangle with the circle inside it.
Choose a soft black brush with a hardness of 0. Your foreground and background colors need to be black and white. Start painting where you want the image to be crisp again. If you go too far, change the brush color to white, paint over the area and the image re-blurs. Black erases. white replaces.
Use the bracket keys [ ] to change the brush size.
x toggles between black and white color choices.
