I know it's been a month since anyone posted but I just came across this and gave it a try on a sensor that was just sitting around. My question is that everyone says that theres 2 layers to remove (lens and cfa) but when I was doing it there was a 3rd one... did i just go to far? You can still see some microlens layer around the edges. Then the green cfa layer. Then theres kind of a clearish layer then what I guess is just the sensor ..please excuse the glass... it made me mad lol
