  Q. using gaussian blur
           Asked by James C   Donor  (K=18903) on 9/29/2007
i saw this photo and thought it was a great idea:

I use PS CS2, anyone know exactly how you do this? just isolate the part of the photo you dont want to blur and then blur the rest? which tools are best to achieve this?

thanks ~ james

i think i've figured it out. open image --> select (select part of the image) --> inverse --> gaussian blur. any other ways to achieve this, or is this it?

one other question: putting a frame around the non-blurred portion, use layers?

You have answered your own questions adequately enough.I wouldn't use a frame around the image myself, perhaps using the elliptical marquee tool might be worth a try.

James, proceeding on the basis that you are using Windows, I try to give your answer. Use the following steps:
1. Open the photo in CS2.
2. Bring the layers pallet by clicking F7
3. Create a duplicate background layer and keep it selected
4. Put the Gaussian blur as much as you want on the whole photo (don't worry)
5. Then while clicking Alt button, click on the add layer mask button at the bottom of the layers pallet (the blur vanishes now)
6. Select a brush tool-choose as much diameter as you need
7. Then set the opacity of the brush at around 10% at the top
8. Check that the layer mask colour is black and the default foreground colour is white in the tools pallet (if not, make it white)
9. Now use the brush to "paint" the blur at the areas you want the blur...

This is the best process that I know. There are many others. Hope it helps you...please tell me for any clarification

Regards

Subhrajit
