I see that there is a lot of confusion about RAW image capture, and what the differences between RAW image capture and JPG only mode.
RAW is an unprocessed, uncompressed image, where as JPG mode is processed using the software on camera and compressed. Both have advantages and disadvantages.
RAW Capture Advantages:
High resolution
Greater options post capture (i.e. noise reduction, sharpening, exposure, white balance, color saturation, etc.) You can increase or decrease exposure by up to 3 stops.
Non-destructive/non-permanent (meaning any changes you make can be zeroed out and start over
RAW Capture Disavantages:
Larger files (up to 20MB per image)
Need to process image prior to uploading to Facebook sending via MMS, Tweeting, etc.
No RAW image processing (right now) built into the device, must be processed on a computer (Windows/Mac). I'm not sure if you can on a Chromebook.
JPG Capture Advantages:
Smaller files (roughly half the size or smaller than the RAW file)
Ability to immediately upload to social media, email, text, etc., without having to convert (process) the file.
Plenty of apps image editing apps available for on device editing (i.e. Nokia Glam Me, 4Blend HDR, etc.)
JPG Capture Disavantages:
Limited post capture options (white balance, exposure, noise reduction, etc. are set by the camera and cannot be changed post capture).
Editing a JPG is destructive, therefoer if you make any changes, it's permanent. You cannot go back and zero out the changes and start over.
So if you want almost TOTAL control in post capture image editing, are not concerned about space, and willing to sit down and download the images to your computer to process them, then RAW capture is for you.
If you are just posting to Facebook, Instagram, emailing, sending MMS, or Tweeting, then stick to JPG capture.
The upshot is that you can change from RAW to JPG capture and back on the fly. Thereby allowing you to tailor your photography to your needs.
