Patrick David's Simple Embossed Watermark in GIMP video: Gimp operations extracted

From time to time I need to watermark some images. I find Patrick David's Simple Embossed Watermark in GIMP video (6:28 minutes) most valuable. In the video he adds some comments and background of what he accomplishes in each step. Which are worth understanding. Yet I had difficulties extracting just the raw steps to implement for my images. Which is why I am writing this page.

The algorithm is:

  1. Start by creating the text of the watermark.

    0:20min / 6:28min
    File → New... → Advanced options → Fill with → White
    0:47min / 6:28min
    Foreground color: pure gray
    1:02min / 6:28min
    Tools → Text (insert the text)
    1:28min / 6:28min
    Turn off the background layer
    1:34min / 6:28min
    Layer → Duplicate Layer of the text
    1:37min / 6:28min
    Select the middle layer
    1:44min / 6:28min
    Colors → Levels → Output Levels to pure white (left and right counters will read 255)
    1:54min / 6:28min
    One can see it by turning off the top layer
    1:57min / 6:28min
    Filters → Blur → Blur
    2:02min / 6:28min
    Move the layer off just a bit
    2:26min / 6:28min
    Layer → Duplicate Layer
    2:31min / 6:28min
    Colors → Levels → Output Levels to pure black (left and right counters will read 0)
    2:40min / 6:28min
    Move the layer off just a bit in the opposite direction to the prevoius movement
    2:56min / 6:28min
    Select the top layer, Layer → New from Visible
    3:11min / 6:28min
    Edit → Copy (Ctrl+C)

  2. Now add the watermark to the image. The next steps are with the image where the water mark is to be added.

    3:13min / 6:28min
    File → Open (Ctrl+O)
    3:16min / 6:28min
    Edit → Paste (Ctrl+V)
    3:28min / 6:28min
    Layer → To New Layer (Shift+Ctrl+N)
    3:38min / 6:28min
    Set the Mode to Overlay
    3:58min / 6:28min
    Layer → Duplicate Layer (Shift+Ctrl+D)
