Originally posted by ismaelg So if I shoot in any of those modes, say portrait mode for example, and I see the settings: shutter speed 60 aperture 5.6. Will the picture be exactly the same as if I go manual and set those exactly? Or does it also affect colors or tones etc?
It does change the color balance, saturation, sharpening etc. for JPEG output.

The raw image data is not changed, so yes it only affects the physical settings. There is metadata in the PEF/DNG file that some software (such as Pentax Photo Lab) can use to match the color/tone/etc settings the camera would have chosen if you like them, but you are free to process the image any way you want.
