Advertisement Posted February 5 Posted February 5 Hi Rich1, Take a look here DXO PL8. I'm sure you'll find what you were looking for!
Chrisbowls Posted February 5 Share #2 Posted February 5 Thank you for the alert, just tried it out and found some significant distortion correction going on. Quite surprising, I must admit; expected less distortion from said lens... Link to post Share on other sites More sharing options...
jaapv Posted February 6 Share #3 Posted February 6 Not surprising at all. Both Q lenses are a hybrid design. That means that the optical part is corrected to shift all aberrations into distortion which is corrected digitally. This enables the designer to produce a higher corrected lens to a smaller size and still keep the cost on a reasonable level. 3 Link to post Share on other sites More sharing options...
jaapv Posted February 6 Share #4 Posted February 6 IT only means that DXO does not fully support the Q43 as the distortion correction is an integral part of the lens design. Link to post Share on other sites More sharing options...
Robert Ardinger Posted February 6 Share #5 Posted February 6 I don't have PL8 but have DXO PureRaw 4 (PR4) which also now supports the Q43 (does PL8 have PR4 built in?). When PR4 does its conversion on a Q43 DNG there is (or at least can be if you look for it) a toggle to turn off/on lens correction. Toggle OFF and the native (I assume native) uncorrected image is shown with its barrel distortion. Toggle On (seems to be the default) and the image has just about the same correction as a Q43 DNG shows when opened up in Lightroom (LR) so at least PR4 does seem to fully support the Q43. I pretty much only use LR and Photoshop but did add PR as a plug-in (just before LR added Enhance/Denoise!) so my experience with DXO conversions is limited to the use of PR4 as an option to LR Denoise. 1 Link to post Share on other sites More sharing options...
BradS Posted February 6 Share #6 Posted February 6 I don't understand. DNG is a standard file format just like JPEG and TIFF. If software can open a DNG cannot it open any and all DNG files? Does the Q3 output RAW files that do not conform to the DNG standard? What does "now supports the Q3 43" in this case mean? Link to post Share on other sites More sharing options...

DNG is just a wrapper for the image files. The files contained within the DNG can be a standard, such as tiff, or proprietary, such as Leica raw files. The software application interpreting the raw image files contained within the DNG has to know the specific format. Hence PhotoLab 8 has only just released an update that “understands” Q3-43 files Link to post Share on other sites More sharing options...
PhotoCruiser Posted February 7 Share #8 Posted February 7 Here is a short write-up from Adobe who developed DNG https://www.adobe.com/creativecloud/file-types/image/comparison/dng-vs-raw.html A much more detailed article on Wikipedia is to find here: https://en.wikipedia.org/wiki/Digital_Negative Chris 1 Link to post Share on other sites More sharing options...

No it cannot open all DNG files. When the M 9 Monochrome 1 was released only Adobe software could open the linear ( demosaiced without RGB information) DNG files. At any rate DNG is not an image file like JPG. It is a data container file for raw data and setting data. Thus it must be converted before it can be displayed, although there can be a jpeg preview embedded. 1 Link to post Share on other sites More sharing options...
BradS Posted February 7 Share #10 Posted February 7 (edited) I guess I don't see the point then. I mean, If the DGN file format is just a container for a proprietary raw data blob, and one still needs some proprietary IP then...it fails to meet the stated objectives. It doesn't make sense to me at all. I thought it was like JPEG or TIFF. I suppose DNG does allow the software architecture to be somewhat regular across various proprietary raw data formats. Perhaps, the DNG spec requires producers of proprietary data blobs to also provide an object module that complies with a standard interface. Hmmm. maybe that's it. EDIT: Even so, I don't see the point of DNG if it is not generic. If the content is, essentially, still proprietary, it doesn't see to accomplish much.

BradS Posted February 7 Share #11 Posted February 7 I've downloaded the DNG Spec document, ver. 1.7.1.0, Sept. 2023 from the Adobe website (link in the references section of the Wikipedia page linked above) and am reading it now. Thanks all. Link to post Share on other sites More sharing options...
