Combining two images with Image Arithmetic. | |
 Original image #1. |  Original image #2. |
| I lightened Image #1 considerably, before doing the image arithmetic thing with it. My first of many attempts at getting a reasonably coherent picture is shown to the right. I used the following settings: Add, all channels, divisor=1, bias=0, no clipping. |  And the result. |
| Another try... | |
