The document discusses various techniques for using or not using a flash in different lighting situations. It provides tips on using higher ISO settings, aperture priority mode, image stabilization and post-processing to improve low-light non-flash photos. Flash can produce washed out images while ambient light results in more natural colors; bounce flash or off-camera flash can provide better lighting than on-camera flash. The assignment is to post a photo using fill flash outside or not using flash inside to rely on ambient light.
