Well being a big star wars fan, one of the first thing I tried in photoshop had to be the light saber, so I tried the simplest method I could think of then which i will be explaining to u below. There is another method that is NOT MINE, but was in the form of a tutorial on _www.ryan-w.com_, which I would be explaining as well. Before this lets keep some points in mind-
1) There are a gazillion more tutorials but none on instructables so here i am
2) I am discribing only the method to add the light saber effect in a picture, (videos are too cumbersome)
Step 1: GET UR PIC!!!!!
Simple get a pic of yourself or anyone holding a stick or a saber. (im using a random pic i found)
