Since I am married to the world's greatest beauty portrait photographer, achieving a new pic would be easy. Flash her a smile with an offer to by drinks afterwards and bam you get an updated photo.
Since, I am also a good student of the craft, she handed the camera back over to me with a set of instructions on how she would like to be photographed. Bam, updated Elizabeth photo (damn she's hot!).
We go home and bask in our extreme good-looking-ness, proceed to talk about what a beautiful creation we have in our daughter. Open up photoshop and stitch together a new family photo.
A photo of you is important, do not forget that. Go get one done!
