Photo I took while snowshoeing at Big White, showing raw image (lower) and adjusted areas (upper). There are a few things the avid photographer should work at excelling in regarding exposure. Getting the right exposure is only part of the equation. Evenly lit scenes, especially under cloudy skies where there are no really bright areas and shadows are soft, rarely present a challenge as modern cameras can capture a properly exposed image with little fiddling, other than perhaps some exposure compensation to deal with an overabundance of dark or light values.
