1. One or more non-transitory computer-readable storage media comprising computer-executable instructions for generating a modified digital image lacking atmospheric effects present in an original digital image from which the modified digital image is generated, the computer-executable instructions directed to steps comprising: receiving the original digital image and original image metadata associated with the original digital image, the original image metadata comprising information about a directly measured distance between an image capture device sourcing the original digital image and at least one object represented within the original digital image; digitally selecting a subsection of the original digital image; determining, with reference to the directly measured distance, a distance between the image capture device and an object represented by the selected subsection of the original digital image; determining, with reference to the original image metadata, an angle between the image capture device and the object represented by the selected subsection of the original digital image; generating a directional transmission coefficient, associated with the selected subsection, with reference to the determined distance, which was determined with reference to the directly measured distance, and the determined angle, the generating being performed independently of initial colors of pixels in the selected subsection of the original digital image; digitally modifying, by a computing device, the selected subsection of the original digital image to remove the atmospheric effects, the digitally modifying being performed with reference to the generated directional transmission coefficient that is associated with the selected subsection; and generating, on the computing device, the modified digital image with the modified selected subsection.
