Gaussian Blur on People

Can somebody tell me how to use gaussian blur on skin tones to make them look spectacular? I have seen some great photos that use it, but when I try it, my photos look nothing like theirs.

What settings are standard?

It's because it not just the blur effect, but a multi-step (e.g. labor intensive) work. Just get the book PhotoShop for Photographers by Scott Kelby as it is all in there.

The simplest way is to first duplicate the layer, then apply the Gaussian blur on the top layer, change the layer property to 'screen' (or you can keep it to 'normal' or experiement with others), then adjust the opacity to your liking. You can also run a bit of eraser (with low opacity) on the subject to remove the blur on that area.

What should the Gaussian settings be?

I don't think there's any set rule, so you should experiment. I just tried around radius 5 (layer - normal, opacity 50%) and it produces a very pleasant effect.

add a layer mask in first & edit that though.. so you can easily paint back any mistake

don't know why the first responder was so unhelpful - the above solutions will work fine in the majority of cases

Ok,

I made an attempt to try and soften the skin here:
Image

I am not satisfied with the results.

Here is what I did:
1. I increased the saturation a bit to boost the colors by adding an adjustment layer . The original photo was a little flat.
2. I added a curves adjustment layer to further separate the model from the background. Only minimal though.
3. I duplicated the background layer twice. On one, I added a gaussian blur about 5.0 pixels 50% opacity. On the other, I sharpened the edges twice.
4. I erased the edges of the gaussian layer. 50% opacity, 25% flow, brush size of about 10-20 depending on where I was on the photo.

My photo looks nowhere as clean as the ones seen on this link:

What am I doing wrong? I have tried to screen the guassian layer, and it just blew out the picture. It was waay too bright.

Thanks for your help.

You might want to try overlay or softlight for your blend mode and see if that works better than screen on your blurred layer.--Rene

Hmm.. that porcelain skin one - the example makes her face look unnaturally desaturated.. don't like that!

Certainly the median effect is worth looking at, tho yet again, the sample doesn't help - so maybe it is more complicated, but i sense that one has to work hard rather than rely on a blanket effect - not a bad thing!

OK, Here is my second attempt.
Image

On top of editing for color, I used the healing tool to remove some blemishes.

Then I used the polygonal lasso tool to select her skin on the background layer.

I stayed close to the edge, but not going over. I also did not select her eyes, side of her nose, lips, and other places so they would stay sharp.

I then smoothed the selection by 2 pixels.

I then contracted the selection by 5 pixels and then feathered it by 5 pixels.

I made layer via copy to just create a layer for her face and then again for her body.

I then added a gaussian blur of 4.0 pixels for both the face and skin. I left the layers at 100% opacity.

Here is another photo using the same exact technique:
Image

I feel like I am a little closer. Your opinions and thoughts ?

It would be bright if you don't reduce the opacity.

I did. I reduced it at different levels and still did not get the effect I wanted.

Actually what i did on this photo is just removed the bad stuff with the spot healing brush on the forehead and on the cheeks. In the end i have applied some Blur Brush on these parts to level the smoothness

Here is the photo:

and here is the original:

Somehow i was not able to repair a photo using the Gaussian blur. It had strange non realistic effects!!!!

OK, by accident I found that the Neat Image plug in actually does wonders for skin.
Image
Here is an image I shot on 35mm some years back. I wanted to use neat image to clean up some of the noise, but just messing around with it, I shocked myself at what I saw in the skin.

Here's another one..

I am really pleased with these results.
