... Obsolete ...

Hi Adam,

I haven't got my manual with me to check, but IMHO RAW is RAW and no optimisation settings in the camera will have any effect on what is recorded in the RAW image. They will have lots of effect to the JPG though.

Cheers

I believe that the optimisation only applies to the jpeg. However, when you use Nikon View to view your raw pictures it shows the changes to the raw. When you open them in photoshop or something else the changes aren't applied. (I think....)

Yes, the image processing settings are used to determine how the JPEG is processed/created.

The settings at the time the photo was taken are stored in the NEF file along with the unprocessed sensor data. Nikon software uses the image settings in the NEF to generate a JPEG similar to what would have been done in camera. With NEF, you can choose to override the settings at a later date and change white balance, colour, or whatever. Hence NEF allows you to recover from some mistakes and/or improve images beyond what can be achieved with JPEG.

RAW file contains all data from the sensor and tagged info from camera's image optimize settings.

That is, it captures all the raw data from the sensor, clips the tag for sharpening, contrast, etc into the file, then when an appropriate software opens the NEF file, it will automatically apply those tagged info into the raw data and produce the image. That is why, you can change deliberately anything you can have in camera image settings on computer if you shot RAW.
