altering my sky
I was using the tool to cut the sky from the land so I could enhance the sky and land seperately.
Maybe the wrong way to do it - I am a novice.
Anyway I made a mistake, clicked in the wrong place.
Ctrl Z did not undo the last point, clicked F and all my work was undone.
What should I have done, before I do it again!

RE: altering my sky
You seem to like keyboard shortcuts, I have been looking for an up-to-date shortcut chart, plenty around but all still have remnants of Gimp 2.6 in them.

Crtl-Z will back off the last operation, down the undo stack see: edit -> preferences -> environment. I think the default is 5 but there is also a memory limit. If nothing happened then maybe you had not completed any operation.

The key 'F' selects the free select tool and that is all it does. If there is an active selection that stays until you complete the free-hand selection. Then it is up to the selection mode, what happens next.

I should not complain about old references since this is Gimp 2.6 as well

but it does demo the different selection tools and modes, just the same in Gimp 2.8

edit: looking back over my videos, a couple that might help

http://www.youtube.com/watch?v=aUHEI-bVSPo

this one deals with fringing that often occurs when trees are involved.

this one is a bit old but shows the use of a mask to remove a sky, it is less destructive than a simple select-and-cut.
All sorts of ways to remove a sky, Much depends on the image. Free-select not always the best way.

RE: altering my sky
When your done with the videos

One way I would go about this is to duplicate your image(it will make new layer)

Make your adjustments on that layer until the sky looks more than half decent(ignore any over darkness, your original picture will be underneath,
then make a loose selection with the lassoFreeselect or pathsPath tools around the sky.)
Be sure to allow enough space around the sky for erasing around it.
*If you select directly around the sky, when you erase you might erase part of the sky easier(you don't want that)
-Selection > Invert...
-Push delete.
Then erase around any parts that are not the sky with a soft edge brush.

RE: altering my sky
Many thanks for the replies.

I have to admit to not getting to grips with masking and layers yet.
I need to spend more time on it.

What I wanted to do was select the sky and give some enhancement and contrast, but not the scene under the sky.

when you're working with layers, if you only work on one layer with your enhancements & contrast, it shouldn't affect the layer below(landscape)

By putting your sky on a separate layer, you can isolate it, good luck! Smile

rich's vids on selections are the gist of how you select very well.

The thing about selections is;
You want to select something complicated.
Look at it the other way, select something you do not really want, the background, sky, maybe even transparency, then invert the selection to get what you want.
