Your post seems to indicate you tried calibrating using my instructions, THEN got prints later.
But that can't be so. My instructions clearly state you must have prints BEFORE calibrating.
No, not even close. The links you gave me have MUCH more blurred backgrounds than that.
Don't skimp on this. The background blur is crucial to the style.
Great. Now, obviously the next step is the background blur. It will be MUCH better if you can achieve it in camera in future, but for now, do this then post for me.
Don't feel bad, it's not your fault. That tool never works. It's an elaborate prank played by somebody with a sense of humour at Adobe HQ. "Let's add this feature to make people think they can extract hair! Ha ha ha!"
