ha ha very funny lol
Don's was the same thing he just showed it with a car in LFS instead, actually if anything his english (no offense don! :razz

made it slightly more confusing.
If that one doesn't help any, do a google search for Photoshop lens blur effect or depth of field or something of the sort.
I remember when don released that thing I started doing that stuff, I even looked at that same cow tutorial that was.. 5 years ago

Once you follow a tutorial and figure it out it's hard to forget it.
