jpg file equivalent to what the camera can produce without the need for any editing on the users part, I'm now pretty confused. Since an idea that I've had up to now is that DPP4 is able to produce a. Another guess is that this lens specific data that is loaded into the camera has no affect on the raw files produced by the camera. Insofar as this lens specific data is only used when processing raw data, I'm also guessing that it needs to be present in the camera if it is to be used by the camera when producing images in. Another guess is that it might be 'Digital Lens Optimizer', which in this case may only apply to certain cameras. Then there is also something called 'DLO' with no mention of what that term (e.g., ? acronym) means.

The user manuals refer to 'Lens aberration correction data' which appears to be applicable for all cameras. Apparently there are some complications (i.e., differences) based on the kind of camera/s being used. I didn't notice anything in the user manuals about this idea. I presume that removing data for unused lens/es might be necessary because of capacity restrictions but that is only a guess. Apparently the camera is preloaded with data for some lenses but, depending on the lens/es being used, it may be necessary to add data for the lens/es being used. Moving on to the EOS Utility, it appears as though it can be used to either add or remove lens correction data to the camera.

Now what? The controls for the various tools are pretty straightforward but what is supposed to happen when they are used is not described? In that, what to look for? So far I've played with them a bit but cannot say that I've noticed any affect. I was able to exercise the control that finds the data and turns the 'Lens Data' indicator from 'No' to 'Yes'. With that tab selected there is a tool called 'Digital Lens Optimizer' that appears to depend on having access to data specific to the lens in question. DPP4 has a tab in the editor called 'Perform image lens correction'. As best I can tell lens correction is something that only applies to the raw (i.e., as yet undeveloped) data.

Having looked through the various user manuals associated with the subject software there is very little information that helps to inform a user just learning about digital image processing what's being done.
