Dust delete data in DPP4
Nov 9, 2020 10:23:28 #
Does anyone use dust delete data in Canon DPP4? I thought I would try it, but after following the in camera steps it is still greyed out in the dpp4 menu. Does this mean I have no dust to delete or am I doing something wrong?

I haven't used that yet, but isn't there a dust info acquisition setting in the camera? Maybe it needs this information to work in DPP? Not sure.

Greyed out options nearly always mean a conflicting feature is enabled. If you, like most of us, haven’t filled up the “Custom” modes (C1, C2, etc), then one or more of the Custom modes is still the default user setup. Select a virgin Custom mode and then check whether the Dust Delete Data menu option becomes available for use.

There is a procedure in camera for shooting a white piece of paper unfocused, which I followed. I usually shoot in C1 and it shows there that the data has been updated. It is in dpp that it is greyed out.

Check these out. One references "dust delete data appended to an image", don't know how...

So getting closer, the camera says I have it turned on, but reading the exif in dpp it says 'dust delete data:no.' I brought the raw in from the camera via lightroom, but the data should still be in the raw file, no?

If the original image is still exists on the card (not imported via LR), try loading the original via DPP.
Maybe Lightroom does something funny with the dust data if LR cannot work with it??? Like drop it?

You probably want to consult your EOS model specific user manual for topic = Appending Dust Delete Data. That additional data will be relevant only to DPP and possibly only applies to images created after this data has been created in the camera.

Did that and followed the procedure. I'll have to check later if Lightroom is not bringing it with the raw, I'll try eos utility to get the raw off the camera. I assumed it was written into the raw and would travel with it no matter how I copied the raw off the camera, but could it be a sidecar of some kind? I'll experiment later.

Adobe will never acknowledge EOS specific data, whether the data is in the RAW file or not. The copied RAW file is unchanged by Adobe, not matter who / what software copies the image files from the card to the computer. But only DPP can possibly see / use this data.
The EOS 6DII manual I checked says the data is appended to the RAW and JPEG files ongoing after you've successfully created in the camera. You might post and store an original JPEG and we can inspect in DPP to confirm.

So I tried it from the beginning. I followed the in camera procedures and I see the note in the dust delete data menu in the camera: Last Updated 11/9/20. Good so far. I was in C1 so I registered C1 again just in case. I took a new photo and downloaded using the Canon utility and opened it is DPP4. Tried the menu item under adjustment/apply dust delete data. It spun a few seconds and returned: Cannot apply dust delete data.
So still a mystery. My only thought is maybe there was not enough dust or not enough contrast to trigger any data (you shoot against a white sheet of paper in the step to gather the data). Can't find anything on the web, but found a few people with a similar problem, no solutions offered.

Without a file to inspect myself, my only other idea would be to assure you have the latest DPP installed.

I'm going to try licking the sensor then touching it to a dog bed. Maybe then there will be some dust to delete.

My understanding is that where 3rd party software is reverse engineered from the raw files, there is data in the raw files that they don’t pick up, so it is possible or even likely such data isn’t included. On the other hand it would appear to be a logical assumption that a raw file is transferred intact with all original information.

I tried with an all Canon workflow, canon eos utility to get files off the camera, canon dpp to open them, no luck.
