samos Posted February 10, 2016 Share Posted February 10, 2016 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 Quote Link to comment Share on other sites More sharing options...
Staff DWright Posted February 10, 2016 Staff Share Posted February 10, 2016 Hi samos, The way to do this is using layers for the adjustments and masks to define the area that the adjustments are applied to. Feathering is the used to blend between layers. There are several ways that you can achieve the effects that you are after I recommend looking at the videos regarding Layers and masking and adjustment from the following link. Have a play with the different adjustments and If you have any questions please ask. samos 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted April 5, 2018 Share Posted April 5, 2018 You can quickly make a starless image of your nebula and place it over the image you want to amend Change the blend mode of the starless layer to overlay and then adjust the fill level - this increases contrast Also try a new adjustment layer - levels with a blend mode of linear light - then adjust the fill and mask the over bright sections Many people don't try the blend modes with a level layer but changing its blend modes can do nearly everything you need - try them all at 50% fill first for great effects Quote Link to comment Share on other sites More sharing options...
