I have an image like this one:

enter image description here

I want to control the edges in order to gradually blend them, like this: enter image description here

Is there a function to do that in Adobe Photoshop? Thanks!

  • It seems like you are already doing it. How did you make the lower image and why can't you use that method? – Wolff Nov 29 '19 at 23:06
  • Substance Designer. I have to learn it from scratch and I though that I could achieve the same in Photoshop quickly. – user840718 Nov 29 '19 at 23:07
  • What do you mean by "learn it from scratch"? What your image is showing seems to using a gaussian blur. Have you tried that? – Billy Kerr Nov 29 '19 at 23:41

Here are two different methods to dynamically blur the edges of a shape.

Method 1: Gaussian blur a Smart Object

  • Right-click the layer and select Convert to Smart Object to convert your layer to a Smart Object and enable applying filters dynamically.
  • Enter Filter > Blur > Gaussian Blur to apply blur to the layer. Press OK when done.
  • Now a Gaussian blur filter is added to the layer. You can enter the settings at a later time by double-clicking the filter below the layer. You can now only edit the contents of the Smart Object layer by double-clicking it.

(This method affects every pixel of your layer.)

Method 2: Layer Mask with Feather

  • Select your layer.
  • Press Ctrl / Cmd + A to select all and then Ctrl / Cmd + C to copy the contents of the layer.
  • Create a black solid color layer.
  • Create a white solid color layer.
  • Hold Alt and left-click the layer mask of the white solid color layer.
  • Press Ctrl / Cmd + V to paste the contents of the layer into the layer mask. Press Ctrl / Cmd + D to deselect. (This only works so easily because your image was black and white to begin with. In a layer mask the darker tone the more transparent the layer gets.)
  • Now, in the Properties panel, you can dynamically control the Feather of the layer.

(This method only affects the edge defined in the layer mask, not the contents of the layer.)

  • It works! Excellent...thanks! – user840718 Nov 30 '19 at 0:22
