Semi Out of Focus Imaging

[Kelz1990]

Hi All,

I am in need of some hints/tips.

One of my partner's band members have asked me to help them with producing some photos for their solo album cover. They are wanting:

"either a semi out of focus backgorund with me in focus on stage or me sitting on a bench playing my gutiar in focus with everyone walking past out of focus"

Is anyone able to advise how I would go about doing something like this, either through my camera itself (Nikon D3100) or through GIMP, as I don't have Photoshop as yet.

Any and all help/tips would be greatly appreciated.

Thanks.
