Debayering a DSLR's Bayer matrix.

[Gina]

This is one fascinating thread , would it not be an idea to contact Canon to ask about the adhesive they use ?

Steve.

You think Canon would tell me?

[Gina]

Yes, if it still works Gina, you should post it on a Canon forum so they can see it. They would freak out.

I think they might

[RAC]

I'm sure canon would have a bucket load of old 1000d sensors they could send me for testing. They should so make a mono camera!

[Chris]

erm I'm starting to think you might be flogging a dead horse Gina? "A" for effort though and if it still works its a testiment to Canons build quality!

[Gina]

I'll test it tomorrow - I want good light to take out all those tiny screws to put it in a working camera. With hundreds of G of shock applied to it the result will be interesting

If it doesn't work I might just break the glass and attack the insides - maybe attack it with chemicals and see what happens. We already know the effect of grinding it down.

[Chris]

One last thought, couldn't you use a Dremel type tool to grind away the glass around the edge?

I've been thinking that myself

I guess I could - I have some grinding tools - good idea

[pixelsaurus]

Keep up the good work. I find this thread riveting.

[allcart]

Can you still buy those Gina?? Haven't seen them for years.

I think it must be worth a go too, though I can't help wondering if you won't end up with something that's impossible to replace.

There is always refridgerant spray. Perhaps freezing it will cause the epoxy to give up.

I simply couldn't contain myself and took the back off my spare 1100D, with the aid of my ring light magnifier, saving the screws onto double sided sticky tape attached to a sheet of paper. Disconnected it's own sensor and connected the test sensor. The result was entirely white frames. I've only viewed the results on the camera screen and the camera was on fully automatic mode. I think I need to connect the camera to computer and run live view with the back completely off (not connected to the main board). Then I can alter exposure easily without juggling camera, test sensor etc. taking great care to prevent anything shorting out. I've put the camera back to it's own sensor now and tested it with a lens - all working fine.

I just tried some paint stripper on a webcam and it cleaned the bayer layer off perfectly in seconds and left a perfectly clean surface. I fell the canon sensor won't be so willing to play ball. Good news for webcam imagers though. Now i need a dead camera to test it with or i might do a little test on the sensor i have alread butchered but just do it in a corner.

Paint stipper does not work on the Canon 1000d sensor, it does nothing at all.

Good

Oh dear - not good

Thank you for posting the results and for doing the tests

No I meant Ajax and Vim.

I might try this on my webcam guide cam!

Oh, I don't know - I don't use aggressive cleaners like those, there are more effective chemical cleaners that don't scratch.

[Gina]

I've brought my netbook indoors and connected up my spare camera. Set to live view and checked first with it's own sensor and then swapped to the test sensor - with a strip of red insulation tape over one half of the sensor area to provide a crude image.

Guess what??? IT WORKS! After all that torture - amazing!!

[Gina]

Next is to attack the glass with a grindstone

[Gina]

Took a grindstone to the glass but it's quite thick - over half a mm - and took quite a lot of grinding through. Having got through it in one place at the side of the sensor away from the tiny gold wires I tried getting a craft knife under the glass. It broke away in pieces. I carefully broke away most of it staying clear of the fine wires. Here is the result photo.

[JamesF]

Does it still work?

I have no idea what that glue must be, but it clearly forms a very strong bond between the glass and the backing. it's almost like it's welded rather than glued.
