I really like her face in this picture, but the background sucks, and is very distracting.

Suggestions? Unfortunately I don't have this one RAW.

No pic here either, but you can cheat and select everything but her face (magnetic or polygon lasso, then invert selection) and run a guassian blur on it (filters/blur/gaussian)

Shannon, there are a couple of different ways to blur a background out... once you get the selection done properly (the Quick Selection tool in CS3 works great, with the Refine Edge control) you can use any combination of blurs and filters that gives a good result. Sometimes you can use a combination of a very weak mosaic (or other art) filter to break up the detail, and then gaussian blur to give the effect of bokeh. It only works well on certain subjects though. Standard gaussian blur also works well on many subjects.

That's really odd...I linked to this one in the same way I've link all my other ones. :(

Here's a clicky: http://picasaweb.google.com/shannon.lantzy/LolaLantzyPuppyPictures/photo#5210991601932426018

I've been looking for that tool all my PS life! :banana: I guess I don't look hard enough. Thanks Jason.

Refine edge is grayed out though...

Gotta have a selection active first.

:lol: I was there at the base of the falls a ways back with Caitlyn and we couldn't figure out if that girl was naked or not so I took a shot with the 70-300.

Just make sure not to over-do it. Its easy to get carried away with PP stuff like that.

I dont think so. Just more a general caution. Its one of those things its easy to get over excited about. I did this with some of my PnS shots before and thought they looked great until I went back much later and said "Damn those are photoshopped"

shannon--put the whiskers back in. you can mask them off very carefully at high magnification. you kind of lucked out because the background behind them is relatively homogeneous, which makes it easier (or even possible).

i have to say that my preferred method is to create a depth map in an alpha channel and then use filters/blur/lens blur to create the OOF effect.

there are a lot of advantages to this method vs. a simple gaussian blur method, especially when the OOF area is not equidistant from the camera... in other words, you need varying levels of focus/blur. an object slightly OOF/blurry is not the same as an object way OOF/blurry with partial opacity.

you can see what i mean in the top edge of the green pillow in my second faux-dof shot--see how you can see the clear edge, then the blurry layer of partial opacity on top of it? i had wanted that pillow to be slightly less OOF than the background (because it was closer to the focus plane) and i tried to fudge it after the fact. what i SHOULD have done is thrown that layer away and regenerated a lens-blur layer with a tweaked alpha channel (aka depth map). but i was in somewhat of a hurry so i didn't.

i know this is a bit difficult to take in all at once but it gets easier!

^ What he said regarding the whiskers. You can use the magic wand tool for some of that stuff, too, at high mag.

Can you describe how you would do "i have to say that my preferred method is to create a depth map in an alpha channel and then use filters/blur/lens blur to create the OOF effect." in PS?

Someone posted a link to a really good tutorial on masking hair awhile ago. Anyone still have that link?

whoops sorry i missed this. it's kind of a long explanation though, so i think i'll start a new thread with a little write up...
