If one tries this course, it's better to add some benzotriazole (or maybe bromide) to it.

Yes, Jorge! It is benzotriazole you want to add (I've done it - back in the 80's). Adding benzotriazole will decrease XR-1's activity, so be careful and add just enough to knock the fog level down - experiment! Adding benzotriazole will also tend to increase contrast with XR-1.

Adding KBr to XR-1 didn't have a noticeable effect on the fog levels.
