This is a simple effect; it enables you to put a watermark on the image.
Clicking on the Image... button allows you to choose an illustration to use as a watermark. Using the slider allows you to modify the intensity of the watermark.
The illustration chosen as an example here is the Time-Lapse Tool text appearing on the top right side of the image. The intensity of the watermark has been set to 50%. And image saved in the PNG format has been used so that the outside of the Time-Lapse Tool logo will be transparent.
If the intensity of the watermark is brought to the 0% position by moving the slider all the way to the right, the watermark becomes completely opaque. Please note that the time lapse software watermark is just a being used as an example in the demo project; it will not show on your projects.
Note: this effect is available in the free version of Time-Lapse Tool.
