Thanks. I've written down all the pointers here. I plead "Guilty - as accused"
And excuse my frustration when trying to post the EXIF files. Too much technology coming at me too fast.
I'm a bit surprised and disappointed with P mode shooting and with the unintended consequences of AF-A focus. I chose those modes because of the automation they provide.
And the shift from Shutter Priority to Program is the consequence of being out in bright sunlight. I simply couldn't read the Control Panel or the LCD. And I'm not in the habit of scrutinizing the viewfinder for camera data. Just for framing.
It's good that the EXIF sort of throws at you "the footprints in the sand." The missteps are clear.
