Ist time here.
Looking at GIMP to supplement DXO PhotoLab. I am starting to do some long exposure "Fine Art" photography and want to know if GIMP can remove horizons? Photo Lab does not do that of course and I have Photoshop CS4 available on my laptop but GIMP sounds promising overall.

It would be helpful if you post an example photo and explain what you mean by removing the horizon.

I do not have any samples of my own. I could link you to a Youtube video but basically it is blending the sky and ocean where they meet at the horizon; so the horizon disappears.

It is going to very much depend on the image. You could try the gimp_gmic_qt plugin, the blend seamless filter. http://www.gmic.eu
Not a wonderful result, but reasonably quick for a largish image.
(1) Select the sky above the horizon. Copy and then paste puts as a new layer in Gimp 3. Kill the selection, Selct -> None.
(2) Use the move tool to "nudge" that layer to cover the horizon.
(3) The gmic plugin and blend
(4) The result, not great, I could probably get a better result if I tweaked the overlap layer a bit to give a better fit with the background.

Very nice Rich! It looks like I have a lot to learn to get to where I want to be. Thanks for the input.

I tried this (I used a photo from Robert Woeger on Unsplash) :

Again, it depends on the photo.
MyPaint brushes are often overlooked because they are considered "too artistic" but they can be used. This the blur brush and it can give a softer effect than the Gimp smudge tool. The MyPaint water brush sometimes worth a try. Before / After

Yes Rich, depends on the photo and when the person is satisfied with the result. It's always nice to see different responses when solving a problem. Thanks for the tips.
