Thanks! I think the original Image in affinity is with 297 mb too big to post it. 
But I don't get how to attach at least a screenshot of the image. Maybe you can help me there

[HSL Shift Adjustment with Posterise Adjustment]

Well, I've got a question referring to the HSL Shift Adjustment. 

 

​I have combined the HSL Adjustment with the Posterise Adjustment to create a really colorful and nice effect on an image. But when I export the picture or even zoom in the colors shift and a quite boring picture develops. 

 

So how is it possible to make these effects static to get my expected picture?
