Apparently Photolab saves all color channel separately in a DNG while Lightroom does not. One of the issues when converting files between Lightroom and Photolab is that the colors are not retained. It would be nice to have the same colour balance between the examples as that distracts from the other differences School vs School by Interceptor121, on FlickrĭXO_Corrected by Interceptor121, on FlickrĭXO_Uncorrected by Interceptor121, on Flickr Images taken with Panasonic GH5 in Nauticam housing with 7 Acrylic port that is the best performing option on the port chart
The images are at full resolution it will take time to load This image has residual barrel distortion in it which has not been corrected The second file has been processed by DxOLab using an optimised profile for the Panasonic 8-18mm lens as you can see there is less crop and the image is sharper with less pull in the cornersįinally there is the same file where distortion correction has been turned off this results in no pull in corners however in my opinion the quality is less than the Dxo Profile. What I can observe is that lightroom is using the lens parameters embedded in the raw file and there is no way to remove the correction the outcome is the lowest quality output in terms of sharpness with some limited pull in the corners but the image is still ok The shots that I am enclosing here are 3 versions of the same RAW files, the first is the file as I processed it in lightroom, the second is the same file where I processed it exporting a DNG and then applying settings in lightroom to my surprise it turned out different, the third is a file where the lens distortion correction has been turned off I have been testing DxO Photolab primarily to deal with rectilinear lenses.Īt first sight the functionality is similar to lightroom then there are some really technical tools but what makes it interesting is the lens profiles by DxOMark
