How to make a cool looking ghost trail?

[true_blue1878]

For example like take the Netherlands flag and drag it across a background sideways while leaving a sort of transparent with slight glow colour trail? 

I have affinity photo 1

Thanks!

While I don’t fully understand what you mean by “sort of transparent” or “slight glow colour”, one quick option would be to duplicate the flag, stretch the duplicate layer, add a mask to the duplicate, and put a gradient fill on the mask – see attached image.

If this isn't what you want then you might need to be a bit more precise in your requirements.

If the embedded image was supposed to be an example of what you want to achieve, I guess I misunderstood.
But according to the description, I would try a shifted copy of the flag + Motion blur, or Gradient, and decrease the Opacity.

This is close to what I want thanks guys!! And is it possible to make it look more natural like if you were to freehand sorta sideways S shaped trail? 

I'll try to find examples of what I mean. But I've seen lots of things done especially in sport or action settings and the player/actor leaves a trail which is kinda like a ghostly glow. 

But this is close to what im trying to achieve but maybe with a smokey glow trail to give like an electric / energised look. Cheers 🙂

You could start by looking into the Motion Blur filter

Good point.. And maybe I can add a glowing outline to the effect after? I'll have a test. Cheers!

There was a tutorial posted in the forums years back that was about this sort of thing but I can’t find it.
However, this thread might be useful: https://forum.affinity.serif.com/index.php?/topic/167212-how-to-create-a-pixel-stretch-effect-in-affinity-photo/
