We are going to take our light painting images and tidy them up today, to get them ready for collaging. 

1. Crop any excess black background

2. Image-->Adjustments-->Levels. Set your black point, and adjust white slider for color if needed.

3. Any other changes you may want. You could change colors in Image-->Adjustments-->Hue/Saturation

When your images are tidy and bright, you can start layering them together in an interesting collage. Think of it like a name banner you create and decorate with glowing images.

1. File--> New. Width 10, Height 3, 300 resolution

2. Paint bucket the background black.

3. Open your light painting files and drag them into your 10x3 document using the move tool.

4. Set the blending mode of the layer to SCREEN.

5. Arrange your name and decorations so they look bright, interesting, and fun. I want to see multiple examples of each technique: writing (your name), silhouette, portrait, and drawings. (See the example I posted a couple days ago. Its a different size, but same idea!)
