I've discovered the highlight priority mode, very nice, but now that I know how it works I wonder, is it a good idea? Essentially it's taking photos at half the ISO setting I actually set and then the brightness levels need stretching back out in post processing by a compatible raw editor that knows what highlight priority mode is.
So if I know my sensor theory right the brightest stop of the sensor is 50% of the brightness levels and each stop down is 50% of what is left so potentially I'm simply throwing away up to half my sensor data in exchange for not blowing any highlights.
If I did not use it I guess I would be bracketing or underexposing to be safe at which point I am back to where I would be using highlight priority but having to process it myself.
