hi i want to blur out the background of an image

had a go with gassian blur, but it seemed to pick a focal point on its own.

can I manually set the focal point?

thanks

would've done the same as darkmotion, but i'd also experiment with layer masks:D

you can't do a proper lens blur if you don't have a proper depth mask. since your image is probably not a 3d render I recommend knocking out the foreground/background objects and blurring each accordingly

Use the blur tool and blur out each and every portion manually as you want it. Tedious, but it's very effective especially when a situation like that is at hand.

Yeah good point^^

If you have a zdepth channel (if it were 3d), you could apply it as a new channel, and perform a selective blur.
