I am trying to use Affinity to process my astronomy images. I want to make the background sky darker (almost black) and the nebula in the foreground, brighter and more colorful. I suspect this is done through layers ... but how do I do this so the area where the nebula edge meets the background edge is not a sharp border but sort of a blending of one into the other. Is this what feathering is all about? thanks

Sorry, that shud have read "bravo" not "brave"

Brave to Stuart Ord. The tutorials go too far and it's hard to make out what the cursor is doing.

Like many, I find it difficult to follow the tutorials. They go by too fast and the cursor is so small I can't see it in time.. Why not cut away to a closeup for a few secs when the cursor is referred to, and have the voice describe where it's actually going, like ... To the lasso, that's the icon on the left, fourth from the top. These type of changes would be helpful for me at least. I'm trying to be constructive here.

I too find I can't make much use of the videos because I can't find what the cursor is pointing at. The producers might consider a couple of things: "Cut" to a closeup shot of the cursor .... and explain at a slower pace what it is, perhaps adding a short description such as " .... That's the lasso shaped icon fourth from the top ...." That wud be helpful. Many of us have this problem of not being able to locate the cursor and when we finally do its too late..

This is an astonomy-based question ... In an image, If I select an object with a lasso, a nebula for example ... but I want to use curves on everything except the nebula ... how do I invert the selection so that only the background would be processed. Im sure it can be done, but I cant figure out how. Thanks for reading.

I am trying the demo version and hope to be able to user the program to process my astronomy images on my Mac. How would I do this: make the image background black(er) ... but not affect the stars, nebulae or galaxies in the foreground? I think it involves curves and/or levels, but I cant figure out how to do this. Many thanks.

I am just beginning and am trying to apply the program to processing astronomy photos that I take. Is there a simple way to make changes in only part of an image, but not the entire image ... for example to increase the contrast of the centre of nebula, but not affect the contrast in the rest of the image. Is this something to do with masks or layers? Sorry to be so clueless. Many thanks
