1. You must have not set ISO to 100 properly because EXIF still shows ISO of 500. Did you close the manual settings UI before taking the shot by chance? If you do that, it goes back to everything auto mode.Some photo taken,with auto mode,seems a bit over exposure. I tried to set the ISO to as low as 100,but nothing different from auto mode.
On my 950, I can save a 16MP .DNG file but I don't know if I can open that type of file in Adobe Photoshop Elements 11. Does anybody out there know? I see where Adobe supports converting other camera's RAW files to a DNG but I can't seem to find out if it will import it directly. You would think it would but you never know...
