How to remove an unwanted shadow
#1
Greetings forum

I want to remove the shadow of a street light from my image.

The background is soil/gravel.

How can I do this? The color picker for a brush picks only one component color.

I am not sure what the process is even called so it is impossible to search for help!

I want to pick up the soil texture and paint over the shadow.

Any help would be gratefully received.

Regards

There are a few ways, it all depends on your image.

Built into Gimp is the clone tool - https://docs.gimp.org/en/gimp-tool-clone.html
Use a fuzzy brush, ctrl-click to select a source, carefully paint over the shadow.

Sorry, I had trouble finding a photo with lamppost / shadow but 30 second example

Another way is create a selection next to the shadow copy / paste and move the pasted area over the shadow.

Using 3rd party plugins.

The usual is a set of plugins resynthesize / heal selection. For linux you might not have python support needed for the heal selection plugin. - Tell us what Gimp / linux you use.

There is also the gimp_gmic_qt plugin which has inpaint filters. Paint a mask using the pencil tool and apply the filter. 30 second example this https://i.imgur.com/Wbimfmi.mp4

If you do a search, many tutorials using all methods.

Can you share the pic? At least a bit with shadowy and some non-shadowy gravel?

Thanks

I have also discovered the 'heal' tool as well as 'clone'.

Now I can put the right term in my Youtube search!

I will not be uploading the picture as it is an old scanned photograph
taken some 30 years ago ( before digital ) of a canberra bomber that was sitting outside
Waterkloof airbase near Pretoria before it was plinthed.

It is now visible on street view ( google earth ) at 25.49.1552S and 28.12.4275E


I wanted to use the photograph as part of my outro on my new
Youtube channel about building a flying RC scale model. I have taken
Youtube's copyright issue very seriously so I am only using photos
I have taken myself.

Many thanks for the help

Tony.

In addition to rich2005's suggestion  "Another way is create a selection next to the shadow copy / paste and move the pasted area over the shadow" you can also first create the selection over the shadow, then move the selection (in move mode- ctrl alt drag) to an adjacent area then copy / undo / paste (ctrl C ctrl Z ctrl V) to paste the adjacent area over the shadow.
