Trouble following the luminosity mask tutorial. |

So I 'm a complete beginner. I just went through all the basic tutorials except the assets folder. I tried to go through the Luminosity mask tutorial, but I'm getting stuck at the "Create Even Darker Masks" section. I don't get results similar to what the tutorial has. When I subtract the lights channel (L) from the darks channel (D) I get something that looks less dark. I think I'm missing a few key steps that would probably be obvious to a more experienced user. I could provide my file for comparison if you want.
Thanks all,
-Kirby

Setting-Steps for enlarging and reducing brushes |

Hello folks,
I use the shortcuts ALT GR-[ and ALT GR-] (WIN) for enlarging and reducing brushes of all kinds.
Unfortunately, the whole thing happens in 1 pixel steps. I would like to change this and increase it to 3 to maybe 5 pixels. Can I put this anywhere?
I searched in vain in the preferences.
Thank you
PS: I use Gimp 2.10 RC1 if this is important for the matter.

Opening a 300dpi JPG changes to 72ppi? |

I make 300dpi JPG-s from CorelDraw. After export from CorelDraw I check the resolution once again in the Win Resource Management from file's properties and it's 300dpi. When I open this JPG in GIMP and check the Properties from Picture> (or Image>) Properties, the resolution is 72x72PPI. Why? I have done this 10 times to check it.
I have configured in GIMP program properties that a new document will be 300x300DPI. But this doesn't help.
If I open a photograph taken with 300dpi cellphone camera in Gimp, the resolution seems to remain 300DPI.
So, somehow my 300 DPI CorelDRaw Graphics are changed to 72PPI. Frustrating!

Atmospheric haze: Add and remove |

I'm working on a project where I am blending a couple different photos of some landscape into a single image.
The problem I've having with this is properly color-matching many of these elements, particularly with regards of atmospheric haze. Some of these mountains and hills were taken from different distances, and as a result some have more atmospheric haze than others, given them more or less of a blue tint.
To get my image to look right, I need to match these properly between each other. Some of these I need to add that blue haze, and for some of them I'd like to remove it.
I thought adding the haze would be easy; I thought I'd be able to just add a new layer of just blue and just adjust the opacity. But that didn't come out right; it didn't look like atmospheric haze, it looked like I just painted it blue. Maybe I'm just a little off and need to use the right shade of blue, or maybe there is something else I'm missing. Either way, I would appreciate some pointers.
I'm also curious if it is possible to remove atmospheric haze. I tried adjusting the color balance to pull some of the blue out of a picture, but then it just looked like I was painting it yellow. I have other pictures of the exact same kind of mountains, so I have samples of exactly what shades of green and brown and such that the various parts need to be. Is there any way I can just automatically match the colors? In fact, that would be really useful because they I can blend it other pictures where the plant-life is a totally different shade of green, or the rocks are a different color, etc.
So does anyone have any thoughts on how I can properly match the colors between these different photographs?

GAP/video |

Hi there
I started working/exploring with GAP using version 2.8.22 and MacOS Sierra 10.12.6
All goes fine until I looked for the video in the menu bar (willing to record my frames into an avi file).
It doesn't exist !
read somewhere that in this new version it's supposed to be in <Image>/Video/Encode/Master Encoder
Unfortunately it's not the case (at least for me).
Can anyone tell me what I'm missing.
Many thanks in advance.
M
