I apologize for not reading through the entire post to see if the subject has come up but does anyone ever stack two polarizer filters (and turn them as needed) to accomplish what a 10 stop ND does? I've used welding glass and tried a few other things but I was curious what others experience was with this.
You'll vignette like crazy! Much easier just to get a 9-10 stop or some welding glass and a couple rubber bands! lol.
