Don't do in Photoshop. Bokeh is best done on camera.

The top picture, in photoshop, roughly select the foreground. (Don't have to be exact, meaning using the lasso tool, and do it in 5 seconds rather than taking 5 minutes to get an exact selection). Then Select > Feather > 95. Repeat the feather 3 times. Then Select > Inverse. Lastly do gaussian blur. Adjust the slider till the picture looks nice.

You'll notice that the foreground in the top picture is also in soft focus. So Select > All, and do gaussian blur again. This time, do just a tiny bit to get the soft-focus effect for the foreground.

To get the warm colour tone, use levels and/or curves.

The bottom picture, bokeh is hard to simulate in Photoshop because you'll note that the bubbles are in sharp focus. Could be done, but takes more time.

did you edit this picture with PF T.J.'s consent/permission?

people ask about soft brightness / contrast and you are talking bokeh? 

the best way is just to play around with contrast setting.

how about just buy this and get it done easily? http://www.niksoftware.com/nikcollection/usa/intro.html

anyway sometimes editing you can't be lazy lor, have to do multiple layers if need to.

I think the 2 photos in the first post, is not just about post editing to get that kind of effect.

And using Gaussian Blur in the other image doesn't work. It looks fake.

I had a similar photo, from my experience, I think it has to do with the lens, large aperture, soft lens, and also slightly overexposed. In the first image (girl looking at her hair), the sky is all washed out, and second picture (blowing bubbles), the flare makes the picture soft too.

Try shooting with the light source or bright background at the back of the model.

Here's a photo I took 1 year ago, I've edited it to a bit warm, but you can see the flare makes the photo soft. Shot with Nikon 50mm f1.8D lens.
