First your video is great, you shot in d log and this is the result you get in d log, but in d log you can retrieve much more information in your video in post, one mistake when shooting Was using Auto particularly with these drones and Mavic in particular what it has done is upped your iso to 400 which will create some unwanted noise in your video, but this can also be retrieved in post, if you don’t want to do much in post just apply a simple lut this will bring out much more dynamic range in your video and it will bring out what you actually saw.
D log is a video mode it’s not as someone said a photo option, raw is the option for stills. If you want a more straight out of camera use one of the colour profiles, they can also be improved in post, using Auto is fine but if your moving in and out of different light you will get lots of bright and dark pictures, get used to manual it will help your footage greatly.
you are not correct
D-Log is a COLOR profile and its applied in both video and photo shooting modes on the mavic... its no different than applying vivid, normal, etc.. its just how the camera will process the image.. and DLOG is a processing.. its not RAW. SIMPLY D-log is just another in camera/drone processing of the image option.
I AGREE that its primarily used for video work BUT there are times to use DLOG for stills and I am experimenting with it but one obvious one would be timed shots to construct hyper laps as it would not be unlike shooting dlog in video.. the compression rate might be different and on the mavic you can't shoot RAW timed intervals below 10 seconds..
now getting into it..
First and foremost.. the mavic does not store a RAW file.. it stores a DNG file which.. spitting hairs is not RAW.. its processes (minimally) but allows the camera to present the image as it thinks it should look based on the settings.. just like it would apply to a jpeg .. more to follow
theoretically, however, if you are shooting RAW/DNG (stills) it should not change the BASE information saved in the RAW/DNG file, as by definition, if applied correctly by DJI, they should be saving the entire output of the sensor prior to processing. HOWEVER, DNG permits AS SHOT settings and the image can have a color / processing profile applied (its non destructive) however when you enter an editor, it doesn't hobble you from pushing the photo as ALL the data is there.. regardless of the initial presentation.
now if you are working with a JPEG that was shot in DLOG then you will not have full sensor information to work with so... its best to get the camera to process the image as close to your liking before it compresses the image into that JPEG.
So if you shoot a JPEG in DLOG while you MAY get more stops of dynamic range (debatable) you are likely to loose too much information to really post it properly although I have post processed a couple JPEGs taken in D-Log and they came out ok but the lighting situation wasn't a difficult one. but for video it may work again for things like a hyper lapse.. I have not tried it yet.. manual hyper lapses from stills.
here is the technical info on DNG
2) What is DNG?
DNG is also considered to be a RAW image file. It is Adobe’s proprietary image standard that was created to store image data in a generic, highly-compatible format, unlike RAW files that have specific formats based on manufacturer and camera type. Although DNG was invented by Adobe and is supported in all Adobe applications, there are other camera manufacturers such as Leica, Hasselblad and Pentax that adopted this standard and use it in their cameras as their native and supported RAW file format.
2.1) What are the Advantages of DNG format?
No need to be worried about proprietary camera RAW formats – once a RAW file in converted to DNG, it will work with any software that can properly read the DNG format.
DNG files can be made smaller than RAW files if minimal or no JPEG Preview is stored within the file.
Changes to images can be written directly into DNG files without having to create separate sidecar XMP files to store this data. This simplifies file management.
DNG files are capable of storing full original RAW files and these RAW files can be later be manually extracted, if needed (note: this will significantly increase DNG file size).
Adobe provides many ways to automatically convert RAW images to DNG format in such programs as Lightroom.
Unlike RAW files, the DNG format includes checksum information in the file to detect and prevent file corruption.
Adobe continues to work on the DNG format, enhancing it year after year and adding more functionality and features.
2.1) What are the Disadvantages of DNG format?
Conversion from RAW to DNG takes extra time during the import process. This can be significant when converting high-resolution images.
DNG does not work with most manufacturer image-processing programs. For example, it doesn’t work with Nikon’s Capture NX software.
DNG strips out most of the unrecognized meta data (such as Active D-Lighting, Picture Controls, Focus Point, etc) from RAW files, making it impossible to retrieve this data from DNG in the future.
Because all changes are written into the DNG file, you need to back up the entire DNG file every time you make changes to it.
