Blurring a Photo Background-Bokeh-Using Gimp Free Software

In this tutorial I will be teaching you how to blur a photo background, or create bokeh, using Gimp free photo editing software.  As most of you know, getting bokeh straight out of the camera with a point and shoot is super hard.  Fortunately, creating bokeh with Gimp is super easy!

1)  Open your photo with Gimp.  Duh!

2) Use the Free Select tool to outline the area you want to keep in focus.
3) File > Copy Visible
4)  Layer > New Layer
5)  Edit > Paste, Then click on the image to anchor it. 
6) Click on the eyeball next to your new layer to turn it off (A) then make sure your background layer is highlighted in gray (B).  Then go to Filters > Blur > Gaussian Blur.  If you can't see your layer box click on CTRL + L and it should pop up.
7)  Make sure your Blur Radius is no less than 30.  In this tutorial I used 50.  The higher the number, the more blur you get.  It's really just a personal preference.
8)  Once the photo has been blurred, turn on your new layer by clicking on the place where the eyeball should be (A).  Your in focus part should now be on top.  Go to Image > Flatten Image (B) and you're done!
Super easy huh!  The only (small) downfall is that you get a slight halo around your in focus area.  As hard as I tried, I couldn't figure out a way to get rid of it. 

If you are a bit picky like me and you have some sharp edges between your in focus area and your out of focus area you can use the Blur tool to help:
Just make sure you have "Blur" clicked and your radius is all the way up to 100.

One of these days, I'll make a tutorial on how to select fine, small areas of photos such as hair.  That way you won't have the problem above :)

There you have it!  You can have bokeh with a point and shoot camera, you just have to do it with your photo editing software :)

You make it seem so easy...but when it comes to editing, I am a gimp!

I don't use Gimp but this is a great tutorial.

Ashley, this tutorial should be useful for Photoshop or other similar software too.

I wonder if there is anything in Lightroom that does this, or if I should try downloading Gimp? With your new camera, is there a way to do this? I have been trying and trying but not successful. Maybe it's just not possible.

I love your GIMP tutorials! Thanks Jamie!

Reaching My Limit--I'm not familiar with Lightroom so I don't know if bokeh can be done with it.
To be honest, I haven't had a whole lot of time to play with my new camera to try out some new features. Right now I'm just working on getting the basic feel for it! I'm gonna try to get bokeh to work with it. I did it with my old camera but only in the macro mode.
