The big advantage of Icontrast is the increase in dynamic range, without that all these small sensor cameras are near useless in bright daylight. You can see this for yourself in your examples, in the first one the sky is still blue but blown out in the second one. If you had set your camera EV to -.3 the sky in the first one would be close to perfect.

You could say 'why not lower the exposure and then raise the shadows in PP', but why bother with that process all the time when the camera will do it for you. I am not exactly sure how it works, some cameras merge two differently exposed images, while some may change the tone curve, so I would be interested to hear from someone who knows exactly how it works also.

So I leave it on all the time, the only down side seems to be the apparent reduction in overall contrast, but I set My Colors, Contrast to +1 to compensate for that, the result is images that are equal to cameras with much larger sensors, in a camera that costs almost nothing.

By the way, I am using Icontrast in the SX260 which can only be set to OFF or AUTO, it is the AUTO mode that I like because it varies with scene content.

Icontrast is the best thing since sliced bread.

You seem to have a far better technical understanding than I.  I have to agree for shooting jpg I always leave iContrast on.  When I shoot RAW I get the same results in PP, but it saves time in PP when shooting jpg to use it.
