Hi every body, I saw your topic a few days ago and got interested I have an old Canon 30D and tried to debayer it. It seems like canon 30D doesn't have the two separated filter of LPF1 and LPF2 and there is only one filter that should be replaced by an IR-cut filter. I went through the process and removed the filter (it looks like three combined filters that can not be separated) and then got rid of the glue around the glass. I tried to lose the glue by pushing the edges of the glass gradually. I dd it successfully, but the glass was not coming out and after 1 hour trying it didn't survive. Finally I started the debayering. I tried to scratch the coating by a hard plastic piece and didn't work. Then I used a toothpick and it scratched it in a few minutes. But, I am not sure which layer/layers I have removed. It seems like I need to remove one more layer. Can someone please help me and tell me which layer/layers are removed. You can see some scratch like defects in the attached last two pics. I thought I have damaged the sensor, but the scratches contain information and it seems like the scratches are what I am supposed to get which means one more layer should be scratched. If it needs one more layer, it would be hard to do by a wooden tool. The camera is now full spectrum and there is nothing in front of the sensor. any help appreciated.
