This invention relates to diffusion transfer photographic processes adapted to be performed in the presence of ambient light and to diffusion transfer products useful in such processes wherein enhanced opacification particularly, in the green region of the visible spectrum is achieved by employing a 7-sulfonamido/5- or 6-sulfamoyl indole phthalein as the light-absorbing, pH-sensitive optical filter agent for the shorter wavelength region of the visible spectrum.
