Briefly This workflow can be used to adjust the sun location and lighting in a shot by moving The Big Slider! To the right the sun sets down the horizon to the left it rises up. The Workflow is originally intended for architectural visualization. It works best with shots that have a clear visible sky in the shot so It would place the sun accordingly.

More in Detail - In this workflow, I apply gradient masks using IC-Light to concentrate the attention of the lighting onto a specific focal point so that the most probable interpretation would be a sun. This mask would be controlled by a number slider so that it would go along side a path defined by a simple math formula. Since the location of the sun follows the mask focal point you can move the sun in your scene.

Since the workflow wouldn't necessarily give this golden-hour effect when then sun sets, I artifically implemented this "Dynamic prompt" which changes the weight of certain prompts according to the position of the number on the number slider. In this example it was the words.

I'm a big fan of Workflows/Scripts that require minimal input therefore I put only one Slider to control them all. Also I made the positioning and controlling of the masks be dependant as much as possible on the resolution of the image (after downscaling it in case the resolution is too high for SD1.5)
