What is the reason why RAW data is not the default value after Nikon D750 is shot in raw format? How to adjust it?

Although the original format file is the original information recording format of the sensor, all parameters are adjustable. But by the way, I also recorded the basic setting information of the camera at that time as a reference for quickly converting JPG files, and there is no need for later adjustment. Such as white balance, optimized calibration options, etc. When recording in RAW format, it is suggested that the white balance should be selected automatically, and the calibration should be optimized according to the shooting scene selection criteria or scenes and portraits.

When the free software ViewNX-i provided by Nikon was first installed, there was no default value. The default value is designed for lazy people. As a general adjustment option of personal movie style, it does not apply to all movies. Please refer to the software manual for how to set the default values. For the post-processing of Nikon RAW format files, the original ViewNX-i is the most convenient and applicable. LR and CR should consider RAW format files such as canon, which is not easy to use

It is worth noting that RAW format records are not omnipotent. Some exposure parameters cannot be changed, such as ISO, shutter speed and aperture combination. If the high ISO setting is wrong (noise obviously deteriorates the image quality), or the exposure parameters are seriously overexposed or underexposed beyond the exposure latitude of the machine, it will be difficult to make up for it.
