retired2014,

There is really nothing to it. First you set the camera to record that way. Second, you open the file in an application that will accept files from your specific camera. (Lightroom is popular. I looked and Snapseed can do it too. Third, you make adjustments to your liking.

The only thing really special is that there is a wider range of what you can do in images that need that wide range. RAWs keep all the light data. JPEGs keep only what the camera senses it needs for the scene.

It has been a few years since I saw an owl peeking out of its hole in a Tuscon cactus. I had a small camera with a short lens. I nearly cried. The only good news was that I can still see it in my "mind's eye".

A week ago I was walking around in the woods they call the Nisqually Wildlife Refuge and I caught what I think is a Barn Owl hiding in a hole of a tree trunk. Was he/she polite enough to pose in decent light? Hell no.

Here is a JPEG exported from the untouched RAW captured in a Panasonic Lumix GX8 M4/3 mirroless with a 100-400 Lumix lens. No time for tripods! Hand held with magical "dual" image stabilization and a small twist of the exposure compensation dial.

Can it be "fixed" in post processing. I put the SOOC RAW on dropbox: https://www.dropbox.com/s/ee6glkckae0uxf6/P1100277.RW2?dl=0

Please consider it public domain so that you can do anything you can or want. But, show me how to fix it!!!
