1. Duplicate the layer (Ctrl + J), put as name “Blur” then convert to intelligent object. Note: In my case I had to cut the image so that the effect is only in the window and not in the whole image.
2. In the “blur” layer add the “Gaussian blur” effect. Filter> Defocus> Gaussian blur, I put “7.6”, but you can put it to your liking.
3. Click Ok, then create a new layer, click on the brush tool, choose the number 23 and enlarge or shrink it to your liking, start painting in the new layer.
4. That’s what I did, but I’m sure you’ll get much better.
5. Move the “Blur” layer on top of all other layers.
6. Right click on the “Blur” layer and create clipping mask.
7. Maybe the effect is not remarkable, but wait, inside the “Blur” layer is the “Gaussian blur” filter that we put before, click on it and the blur window will come out again, I put it in “10” but you can adjust it as you want, click OK
8. Place the rain image on top of everything, I’ll leave it in the description to download the photo, but you can use another one that you like. Note:In my case I had to cut it so that it only came out in the window.
9. Select the rain image and from “Normal”, turn it to “Soft light” and you’re done. You can adjust the levels, the tones to your liking so that the photo is even better.
