The Mark of Cain is highlighted on the forehead of the individuals in the photograph.
The Mark of Cain is not a disorderly coloration of the forehead as the examples show that the corners and shape are defined in the form of a rectangular colorized (brown-red-dark red) stamp.
The Mark of Cain should not be confused with the presence of colorization revealed by the BioMarx app filter in the photograph, since it is well-defined and appears as a colorized stamp across the forehead.
BEST PRACTICES
To produce the best photographs, multiple images in varying light can produce the best results.
It is counter-productive and un-natural to produce photographs without shadows or with excessive light.
A clear balance that provides a natural photograph can improve the results.
