1. A method comprising:
processing, using one or more processors, a plurality of channels associated with color information in a color space of an image to generate a second plurality of channels associated with corrected color information in a corrected color space;
determining, using the one or more processors, a plurality of luminance values based at least in part on the second plurality of channels and an exposure value of a camera that captured the image; and
generating, using the one or more processors, an updated version of the image using the plurality of luminance values.
