I generally use this app:
https://play.google.com/store/apps/details?id=photo.editor.photoeditor.photoeditorpro
And for the filters, as the title says, I used literally every filter and cranked them all up to max.
If you want to better know how to use the app, here:
have not tried but i would recommend https://play.google.com/store/apps/details?id=com.pcvirt.ImageEditor&gl=US
should have all the capabilities you need.
So I actually made this "mod" and i completely forgot about it until decided to subject himself to it. Everything in it is randomized and the only things i made myself are the corrupted character models.
As for editing software, I use too apps.
In case anyone would like to know or use it.
