New millimeter Galactic plane surveys are identifying thousands of massive star-forming clumps, but cannot give any information about the embedded sources. Ideally we would like an automated method of identifying the protostellar content that can be applied to the much larger sample of clumps being discovered by these surveys. As a test case, we performed aperture photometry as well as automated PSF photometry on a sample of 20 massive star-forming clumps. 2MASS and GLIMPSE images were used to obtain photometry at wavelengths ranging from 1.25 to 8.0 microns. Protostars are clearly detected at wavelengths between 1.25 and 4.5 microns. Longward of 4.5 microns diffuse PAH emission becomes problematic. We present the results of a comparison between these two methods, and discuss implications for future work.
