Hi born2see.So what software are you using? In your other topic you said you'd let us know. Also it implies it has to be done with a camera. I guess in today's digital world you don't need a physical camera anymore.
I have tried the software which you can download, but it doesn't do a good enough job as this website does.
Website link which converts over your screenshot: http://tiltshiftmaker.com/
Take your screenshot, visit the website, upload it, tweak it, select your photo size, download it, and post it.
Here is another conversion.
[InCombat] If you wish to download the program, I'll post the link.
Later.
