Here I show you how you can get rid of unnecessary lines and the discoloration in a picture.

This nice drawing is from Adrahasis and I got his permission to use it for this example, thanks again for that.

First I removed the lines at the rim with the patch tool and with the clone stamp tool. In this image I also increased the contrast so it doesn't look that foggy. Afterwards I changed the color so that the drawing looks more like grayscale. I decreased the saturation. I didn't desaturated the image completely cause it will look unnatural cold.

In the last picture you see the drawing with a warm light. Usually I like the gray version more but in this case, I think the vintage look fits quite good.

Klick the image to fullscreen, to see the original version and the two versions from me.

I hope you learned something and I'm looking forward to edit the images for you guys.
