One of the options within the menu system of the Canon 90D is Digital Lens Optimisation (DLO). It is ‘on’ by default. I know what DLO is, it corrects for known lens aberrations. I also know that DLO is a feature available within Canon’s own software, DPP, where it behaves a bit like Photolab’s lens corrections, in that a lens profile is downloaded and applied during post-processing.
What I’ve not been able to figure out, despite extensive Googling, is whether or not using in-camera DLO adds the lens correction data to the RAW file and, more importantly, if it does, how third party software like Photolab (or Adobe’s Camera Raw) handles that extra DLO data within the RAW file.
I assume using in-camera DLO will add the lens corrections to the RAW file but that only Canon’s own software (DPP) can read/use these corrections. In other words, I assume Photolab cannot read/ignores any in-camera DLO lens corrections when it opens the RAW file and instead applies it’s own lens correction magic.
Please can a member of DXO staff clarify how Photolab handles Canon’s in-camera DLO?
