I use a script i wrote that uses an open source cli program along with some libraries. I just right-click on the folder and select
Clean PS Watermarks.
If you want a suggestion for a program you can use to easily remove the watermarks manually, HitPaw Watermark Remover is very good and you can do sexporncomic ones super fast because they are very visible. It also works for the giant PS ones but i just don't want to do anything manually.
Obviously i am not gonna remove non-existant watermarks. The watermarks were only on 73, 74, 77 & 80. I cleaned those. I never said i cleaned the ones from sexporncomics! Why would i do that when i have access to the original ones directly from PS?
And there is no way you know what program i use since it is not something specifically to clean watermarks.
When i say i use 2 programs, i use my script to first clean the images and then i run them through a sharpener software to put back some of the details lost by removing the watermarks with the neural network.
