In this how-to I will show you how to blur the background of your photos using GIMP. I like this kind of cool effect who makes the photos more "professionnal"
In the image below you can see some cool examples of nice photos with blur backgrounds I found (photo credits in outro).
Finish the main selection by joining the start point with the last point of selection. Just click around until you reach the last point, then click on it.
Now we need to remove some parts of the selection, because we just want the girl to be selected. Just switch the lasso to "Subtract mode" so each selection we will make will be removed from the existing selection.
Double-click the layer named "Floating Selection (Floated Layer)" to rename it to "girl". Doing that will transform the floated layer into a "normal" layer.
Now we need to reduce to white part in the background layer. To do it we will duplicate the background into the white shape. Click the stamp icon to start cloning!
To start cloning, GIMP needs a "source circle". To set a "source circle", press
Ctrl
then click somewhere in the image. Here, we want to clone the background into the white part so just set the source in (1) then put your mouse at the right side of it to get ready to clone.
For the horizontal parts, just do the same as step 15 but horizontally: β’ Set the source circle up then put your mouse on the bottom β’ hold left click and clone all the way to the right
Each time you release the left click, the source circle comes back to its original position. This can be useful for the right armpit, so we can spread around the grey background!
