Change the JPEG style to the most neutral setting. Change the color space to Adobe RGB, which won't affect the DNGs – but it will make the live view image and histogram more closely match what you get when you open the DNG in post. Do you need to turn on JPEG to change the styles and color space with the Q2? I can set styles and color space without generating a JPEG image on my Q. I do that to set the viewfinder/rear screen in monochrome mode. The Q uses those settings to create the embedded thumbnail. Link to post Share on other sites More sharing options...

True, but with JPEG off and I go to review an image on the rear LCD/EVF: Am I not reviewing the lower-res JPEG previews embedded in the DNG instead of the separate high-res JPEGs?

I never review images until I get them in LR. If I think I’ve made a mistake with a shot it’s faster to take a second shot rather than review in camera. It’s easier to delete a poor shot in LR and work on any changes I want to make on the shot I kept of the same subject. Link to post Share on other sites More sharing options...

Makes me wish Leica made a Q2-D 🙂 I'm probably too addicted to viewing images on the Q2 LCD with a quick spin of the control wheel or double-tap to zoom in all the way.

I don't know for sure, but I think not. And the reason I think not is looking at available metadata from any image taken with my Q. It contains two binary fields: "Jpg from Raw" and "Preview Image". Here are the values from a sample image (Q, not Q2) Image Size : 6120x4016 Jpg From Raw : (Binary data 1200881 bytes, use -b option to extract) Megapixels : 24.6 Preview Image : (Binary data 147069 bytes, use -b option to extract) Note that the JpgFromRaw image is 1.2 MB in size. I extracted that metadata. It is a 6000x4000 jpeg image. The preview image is a 1620x1080 jpeg file. Because my camera was set to B&W the two embedded images were processed as B&W.

The JPEG embedded in Q2's DNG file is a TIF with dimensions 8368 x 5584 (full size). P.S.: you can use ERawP application to extract the embedded JPEG.

The extracted embedded data is saved as <filename>.tif . In most cases TIFF files are lossless, but they can be lossy with JPEG compression. 1 Link to post Share on other sites More sharing options...
