Colours are encoded in 16 bits but only a portion of it is used (14 bits for instance on high-end cameras), the rest is filled with zeroes. Anyway I found the answer to my question by analyzing the DNG itself. So it appears that my Xiaomi MI 8 (main back) camera sensor has a bit-depth of 10, which is good enough I guess (but I am no expert). For the curious, here's how to do it: 1/ optional: shoot a bright picture (straight to the sun for instance) 2/ convert the RAW file (.dng for instance) in .pgm...
Indeed, I don't think it is a data made available easily. It's a shame. Anyway I found the answer to my question by analyzing the DNG itself.

For the curious, here's how to do it: 1/ optional: shoot a bright picture (straight to the sun for instance) 2/ convert the RAW file (.dng for instance) in .pgm with dcraw (dcraw.exe -E -4 filename.dng) 3/ find the brightest...
I checked on my phone and the following apps provide this feature: Waze, Locus Map, Bluecoins, Mi Drop, My cars. I haven't coded in Android for years so I cannot tell you how it is done but the developpers of those apps found a way to do it. Hopefully, it might be straightforward to implement.

When I save pictures in RAW DNG format it is saved in uncompressed format with 16 bits per pixel. I deduced this by the fact that there is no embedded jpeg in the DNG and that the size of the files is slightly superior to the number of megapixels times 2 bytes (16 bits). Obviously only a subpart of those 16 bits per pixel is used (most expensive cameras use 12 or 14 bits so I don’t expect that much in my 300€ smartphone). Searching the Internet showed me that this info (sensor’s native bit-depth)...
Hi, If you need to remove EXIF metada, you still can do it afterwards (on your PC) with ExifTool. For instance to remove all EXIF metada in a picture called "filename.jpg", you simply need to write the following command line: exiftool -all= filename.jpg ExifTool is really powerfull and you can do much (much) more to match any need you might have. Next step being to perform this recursively for all the pictures in one folder, etc.
I am not a native English so my Android phone is set to my mother tongue and so is Open Camera but I’d rather have it in English. I like to have the "technical" apps set in English and most of them have such a parameter available to the user. Open Camera does not or I am not able to find it. Can you please add this feature?
