[Gimp-user] from the shadows . . .

[dep <dep drippingwithirony com>]

greetings, everybody.

one of the things i've long hoped for, that photoshop has had and gimp 
hadn't but now does in 2.10.x, is the highlight/shadow controls.

but i'm a bit puzzled by one aspect, and i'm hoping someone here can help 
me sort what i'm getting wrong.

when i use the shadow control to bring detail out of the muck, past a 
certain point it also adds blotchiness to areas such as the sky. should i 
try to generally select the areas i want to de-shadow, or is there some 
other control or setting that will help with this? the three sliders at 
the bottom of the control, white point, radius, and compress, are not 
particularly intuitive to me, but i'm guessing some relief might be found 
there.

i suppose i could experiment, but i thought if the answer is known and 
simple i needn't try to discover it.

thanks in advance.
