Managing levels in two different parts of the image? |

Hi!
I cannot find out to do this so posting here:
I have an image of a bright sky over a grass in the foreground. The sky is far brighter. Now I want to adjust levels, so that I get a lot of detail in the sky, that is, darkening it, without making the foreground black. So essentially treating the two parts of the image indepently in terms of levels, brightness, contrast. My idea is to do this with some kind of mask, or to separate in two different layers, but I cannot figure out how (I'm quite a newbie to GIMP, trying to learn).
Anyone have advice or can point to a good tutorial somewhere?
EDIT: GIMP 2.8.22, running on Ubuntu 18.04
A scaled down version of the image is here:

Hi, All,
Noob here. I am trying to write a very simple GIMP-python script; all I want to do is:
(a) starting with a clean background
(b) read a .jpg file from my disk into an image object (e.g., a blue sky with clouds)
© have the image appear on top of the background
(d) write some text in black on top of the image (e.g., "Sample Text")
(e) save the whole thing as a new .png file somewhere on my disk.
I am almost all the way there; I am getting an error when I save (noted below) using this line:
pdb.gimp_file_save(1, new_img, layer, outputpath, 'AAA_TEST.png')
Thanks in advance! All help is welcome!
CODE FOLLOWS:
def python_sample_scriptC(image, layer) : #FUNCTION DEFINITION
pdb.gimp_image_undo_group_start(image)
pdb.gimp_context_push()
imagepath = 'G:/Users/Star/Dropbox/Projects/Stock photos/blue-clouds-day-53594.jpg'
outputpath = 'G:/Users/Star/Dropbox/Projects/Stock photos/AAA_TEST.png'
text = 'SAMPLE TEXT'
drawableFLAG = None
xval = 10
yval = 10
borderval = 0
antialiasFLAG = FALSE
sizeval = 100
sizetypeval = 1
fontnameval = 'Arial Heavy'
pdb.gimp_message('LOAD IMAGE')
imageobj = pdb.file_jpeg_load(imagepath, imagepath)
pdb.gimp_display_new(imageobj)
pdb.gimp_message('CREATE TEXT LAYER')
textlayerval = pdb.gimp_text_fontname(imageobj, drawableFLAG, xval, yval, text, borderval, antialiasFLAG, sizeval, sizetypeval, fontnameval)
pdb.gimp_message('SET TEXT COLOR')
pdb.gimp_text_layer_set_color(textlayerval, '#ff0000')
time.sleep(1)
pdb.gimp_message('DUPLICATE')
new_image = pdb.gimp_image_duplicate(imageobj)
pdb.gimp_message('MERGE')
layer = pdb.gimp_image_merge_visible_layers(new_image, CLIP_TO_IMAGE)
pdb.gimp_message('SAVE')
# THE CODE FAILS ON THE NEXT LINE
pdb.gimp_file_save(1, new_img, layer, outputpath, 'AAA_TEST.png')
pdb.gimp_context_pop()
pdb.gimp_image_undo_group_end(image)
pdb.gimp_displays_flush()
#return

Alignment tool layer lock 2.10.10 |

In GIMP 2.10.10 layer locking works fine with the move tool, ie all locked layers are moved, but has no apparent effect using the Alignment tool, where only the currently set layer is aligned.
Is this a 'feature' or a bug?
