Thanks! I'll try your advices! 

[I need an idea to recreate an effect]

Hey!
After using Corel products since the 90s I changed to Affinity Designer and Photo and I love both programms. I'm not a professional designer so perhaps my problem will be ridiculous for pros.

I want to recreate the effect from an album cover. Here's a link to it on Wikipedia: https://en.wikipedia.org/wiki/Some_Friendly
I want to blur a photo with a similar effect. Just to reduce the sharpness isn't enough for my project, there has to be some (symmetrical would be fine!) pattern like an the original cover.

Any ideas? Sorry for the amateur description! Remember, I'm far from a professional user
Thanks!
Christoph

Hallo!

Ich möchte gerne den Unschärfe-Effekt eines Plattencovers mit Affinity Photo nachbauen. Hier der Link zum Original: https://en.wikipedia.org/wiki/Some_Friendly
Natürlich muß das keine 1:1 Kopie sein, nur eine Annäherung an den Effekt.

Leider bin ich alles andere als ein Design-Profi, daher brauche ich Hilfe.
Danke!
Christoph
