A sample 16mm scan from the Retroscan 2K


That looks remarkably like dust on a filter in front of the sensor itself - I see this all the time with digital cinema cameras where lens changes in, shall we say, less than ideal conditions are frequent. It’s very rare to have a bare sensor in an imaging device, usually there is some kind of filter in front, e.g. IR filter, OLPF, cover glass, etc. So when dust (or a scratch or defect) gets on one of these filters, it forms a shadow that looks an awful lot like what you’ve got there. If you’re nearby any camera shop, they’d probably have someone who could at least take a look at it on a bench and do a cleaning pass on it.


I would never have touched the sensor if Roger Evans had not told me how to do it.

So I did it. It worked! (What can I tell you?)

Otherwise, I agree with you. I don’t want to touch the sensor at all.


I’m happy it worked out for you.

There was a guy on the photo forums that ruined his sensor screwing around with it and some commercial cleaning kit. I think it was a ‘dry’ kit that was supposed to pick off debris. I think has cam was a few thousand $$…now destroyed.

Anyone know what the big $$ film scanners use for cams?
