Ultra Raw format

[Crzyhorse79]

I have Xiaomi 15 Ultra, global version and I was starting to test the camera. When shooting in UltraRaw, I cannot recover highlights as I can do with standard raw files. In theory I should have at least the same recover possibilities I have on raw files (uraw weight almost three times a standard raw). I have tried with many software (RawTherapy, DarkTable, LightRoom on Desktop, Snapseed, Lightroom and Xiaomi Gallery on the smartphone), but I always get the same results.
Is anyone experiencing the same? Am I doing something wrong or is there any configuration somewhere?

Same here, for some reasons the raw files (not only ultra raw) are overexposed. The exposure does not match the shown histogram. Support needs to fix that, I hope you opened a case.

Btw. there are more raw related issues:

​

Exposure Presets Do Not Work with RAW​

• Issue: The saved exposure presets always switch the image format to JPG, even if RAW was previously selected.
• Expected Behavior: Presets should either store the selected image format or ignore it (keeping RAW if it was active before).

Switching Cameras in 50MP RAW Mode Forces JPG​

• Issue: If you switch to a camera that does not support 50MP RAW, the system automatically switches to JPG. Even when switching back to the main camera, the setting remains JPG.
• Suggestion: Add an option to oritize either 50MP or RAW when changing camerSO Inconsistencies in Pro Mode (JPG vs. DNG
• Issue: When shooting in ProMode, if I set the ISO to a specific value (e.g., ISO 12.500), the JPG file reflects that ISO correctly. However, the corresponding DNG file is recorded at a significantly different ISO (e.g., ISO 6410). The JPG appears soft and muddy, whereas the DNG looks clear and preserves details.
• Expected Behavior: Both JPG and DNG files should maintain the same ISO value to ensure consistent exposure and image quality. Since the JPG is essentially an extracted copy of the DNG, both files should exhibit the same level of detail.

Missing GPS Coordinates in DNG Files​

• Issue: When shooting in Pro Mode, GPS coordinates are stored in the JPG file but missing in the corresponding DNG file.
• Expected Behavior: GPS data should be included in both file formats, as it is essential for geotagging and later image management.

ISO Inconsistencies in Pro Mode (JPG vs. DNG)​

• Issue: When shooting in ProMode, if I set the ISO to a specific value (e.g., ISO 12.500), the JPG file reflects that ISO correctly. However, the corresponding DNG file is recorded at a significantly different ISO (e.g., ISO 6410). The JPG appears soft and muddy, whereas the DNG looks clear and preserves details.
• Expected Behavior: Both JPG and DNG files should maintain the same ISO value to ensure consistent exposure and image quality. Since the JPG is essentially an extracted copy of the DNG, both files should exhibit the same level of detail.

ProMode dng+jpg produces unusable soft jpgs​

• Issue: When using Pro Mode with the “DNG+JPG” setting enabled, the resulting JPGs are significantly worse. They are noticeably softer, duller, and lacks detail compared to the DNG .
• Interestingly, if you switch to JPG-only in Pro Mode (no DNG), the resulting JPG is much better. This suggests that the bad JPG quality is directly tied to the DNG+JPG combination (storing the low quality embedded preview as jpg copy?).
• Expected Behavior: Jpg should have the about the same level of details as the dng and not look like a 10% compression level copy

other Inconsistencies:​

Inconsistent Focal Length on HP9​

• Issue: In Photo Mode, the HP9 sensor is used at a 4.1x magnification, corresponding to a focal length of about 96mm. In Pro Mode, however, it is labeled as 4.3x, which corresponds to approximately 100mm. Both modes produce images with the same field of view, meaning one of the labels is incorrect.
• Expected Behavior: The labels should be consistent and accurately reflect the true focal length.
• Update: Auto Mode now starts at 4.3x and is called 100mm, ProMode at 4.3x is still wider (sams as what was previously called 4.1x 96mm in Photo Mode) but also called 4.3x 100mm, can't be both correct.
