    Most images posted here are aimed at conventionally high image quality in addition to good composition.

    There is a class of processing called "Mapping" which can improve global image quality in one shot as opposed to messing with a number of editor sliders until it looks right.

    One such pre-AI mapping is called "Retinex" - invented by E. Land of the Polaroid Co. long ago. Popular for aerial shots or scenes with haze, fog or mist.

    I simulated such a scene in the GIMP:

    Then applied a Retinex mapping with the G'MIC plugin and no subsequent adjustments:

    Talk about 'cutting through the mist' !!
