I have a simple (I hope) nube problem.
I open a jpeg in Affinity Photo 2. I add an adjustment layer. I am just reducing the brightness of a black and white sketch. So I have a background later and now there is an adjustment overlaid on top of it (in the same layer). But I can move that into a separate layer, which I do (though same problem either way, whether I move the adjustment into its own line or not). So I now have a background (original) layer and also an adjustment layer (reducing brightness). I can group them or not (same problem either way). I can move one layer above the other, which as expected applies the effect in the main screen or not (depending on the order, as expected). When in the right order I can see the adjustment in the main window. It also appears at the bottom of the sidebar (below the layers). So it looks like I have successfully added my adjustment. It looks great, just how I want it. So I go to export my adjusted image. I choose File/Export and choose my format (same problem whatever the format). In the export panel the preview is not adjusted. It is the original image, not the adjusted image. Sure enough, when I export I just get a file with the original, unadjusted image. No difference if (prior to export) I select one layer or both layers, or group the layers. I have also tried using the Export persona with a slice. Same experience/outcome - the adjustment is not included in the exported file. Though (prior to export) I can see the adjusted image in the main window, no matter what I do I can't get the adjusted image to export.
I can't work out where I am going wrong. Any assistance would be appreciated.
