My point was mostly we shouldn't expect JPEG and DNG to match because of the color depth differance and it espically will show up in Greens and some in yellows. RAW images are also not usually just pure raw data either unless you have a snowflake camera. The Mavic 3 (especially being DNG files) are based off TIFF format and if you look at the DNG metadata it will tell you it's Raster image data. It just has more data and a profile that doesn't match a standard like JPEG.
All camera RAWs are processed in some form otherwise collecting and trying to store actual analog data would have much larger files. RAW files are just less processed and store more data.
OK, but that's not really the point I'm on. I've tried to be fair to DJI all the way on this thread. Yes, DNGs are processed to some degree, but they are meant to represent raw data from the sensor. A jpg is already heavily processed with a color profile, color space, photo style (contrast adjustments etc). So, yes, a jpg will usually look somewhat different than an _unprocessed_ DNG. But, what I'm seeing in my DNG files is significantly incorrect color, especially in the yellows and greens. Not easily corrected without a proper color profile/mapping for the sensor from DJI. Another way of looking at it is : I should be able to process my DNG file to look identical to the camera-produced jpg (same bit depth, color space) but, again, without a DJI-provided color mapping/profile that is very difficult. I would think it would be a top priority of DJI to provide this, given their focus on imaging with the Mavic 3. |
