I bought that camera to experiment, so i may end up destroying it. I'll make more tests.

For it to work the muck needs to be near where the image is focused.

With Through the viewfinder that happens, muck on the sensor glass it's only close enough at small apertures try a pinhole 'lens' that will show it all! - Dirty lenses/filters will just reduce contrast.

It only makes sense to do tests that have a chance of working.
