I just wanted to share this with you all because ... it is very cool stuff in Photoshop.

I recently posted this first photo of the twin pines.  I wasn't quite satisfied.  When I came back to it a few days later I realized what the problem was – I should have shot it at a much wider aperture, say f/5.6 or even f/4 rather than f/16 in order to really have the two pines stand out. As it is, everything is a bit too busy and the pines don't quite get the full billing that was intended.   Well I can’t go back and reshoot but there is an amazing application in Photoshop called Lens Blur.  It involves making what is called a "depth mask", which determines what will be in focus and the extent to which the focus fades.  But once that is done, and in this photo it was pretty easy, it is only a matter of deciding how wide an aperture effect I wanted to have and setting it up.  This application didn’t make this photo great but it certainly improved it and got it more in line with what I’d envisioned.  Very cool stuff.

That makes all the difference in the world. The two trees almost get lost in the first photo, but smack one in the face in the second. ON1 Photo RAW has a similar lens blur tool. I have not tried it yet, but as you demonstrated, it can be a game changer. Nice work and thanks for showing this.

Wow, the trees really stand out. Almost has a 3D appearance....certainly lives up to "depth mask" name!

I have used the tool on occasion with with wildlife photos to separate the subject from the background. When used very subtlety I have found it useful but to my eye it looks different then the real blur created by dof when cranked up.

There's no question that the optimum would be to have done this in camera.  But its a good technique to have in my back pocket for where a large aperture either isn't possible or where I just plain forget  :blink:
