674224 2008-05-31 05:53:00 Hi there

Anyone have a suggestion as to an easy way to create a Depth of field effect on an image .

Ive been trying to do this for the past hour but not getting very far .

Basically I create a second copy of an image, blur it, then switch to the original and cut away everything but what I want crisp and clear in the front, then merge the two together .

In my attempt today, Ive not been very successful, I cant get the Magnetic Lasso to work as once Ive completed my selection whereever I move the mouse to say the toolbar, it add to the magnetic selecton .

Thanks

John in Mosgiel

674226 2008-05-31 08:32:00 Use the pen tool to outline what you want to stay in focus, right-click>define selection, Select inverse, Then filter,blur as required.

No idea really if thats what you want as your question is a bit messy, So I'll do a pic,upload it, and you can tell if thats what you were after...

If you want to that is, You could just ignore me all entirely.

674227 2008-05-31 08:41:00 Start with Quick Mask (Q), use Gradient tool (3rd from left-B to W), put G tool where you want it remaining in focus dragging to where you want out of focus. It will now look red to transparent.
Press Q again to come out of Quick mask. Go to Filter, Blur, Gaussian Blur and enter the amount of blur you want at farthest point on image and press ok.
Go to Select and chose Inverse (which switches the selected area from the blurred area to the in-focus area.
Apply Unsharpen Mask to the area that's supposed to be in focus. Try 150 for Amount, 1 for Radius, 4 for Threshold - then OK.
Deselect by pressing Control-D. (a la Scott Kelby for Photoshop CS but should work in CS2) :)

674231 2008-05-31 11:35:00 That's quite effective!


I like the radial blur applied to the rims.....


And it just occurred to me I was playing with a tool the other day that sounds like it works along the lines of whats described by RM, a blur based on a gradient map, I think it might have been incorporated into Picasso 2.
