Use Luce for doing random rays

Doing Smoke text

Make the background layer black, and write on another layer (photoshop make it in automatic) your text, on write (image 1). Duplicate and rasterize the layer. And doing luce on back layer (image 2).
Now create a new image, and do it more greater of you original, width equal 2 time original width and height equal 4 time original height, or other, and doing the Render->Clouds, remember: if you use power of 2 for dimension, the result image will be tileable. Resample the image to original dimension (without “Constrain Proportions”), use Levels and curves (In the example I don't use curve) to adjust the cloud (image 3). Copy this image on a layer between copies of text, and use Blend mode Multiply (and try other ;) ) (image 4).
On site title, I doing the cloud tileable and move it.


The moon light

Take an image, I take an old photo of a motor same model of mine. Make the contor if it don't have (for do it, I duplicate the background layer and with the magic wand I select and delete the white areas).
Now we want make a base for luce, with a white motor, a black background and a light source moon like. For do it, I duplicate the motor layer (the original will be useful later) and apply the color overlay on white, with canvas size add border to image and move all motor on bottom left corner. After do a black background layer, and put a circle on top right corner, merging the backgroung and the white motor, and it is the result:
Now Apply Luce, with the light form algoritm, and without "add source". Show the original image and it is all. Bellow the result, with opacity of original to 50%.
Other interessant effect can be create use other Blend mode.
The same effect can be create use the follow image and Zero color algoritm:
