  We have developed photometric techniques that can be applied to images with
highly-variable backgrounds, as well as to slightly-extended objects (object
size comparable to or smaller than PSF size). We have shown that ordinary
stellar PSF-fitting photometry can be applied to slightly-extended objects,
provided that one applies a systematic correction to the photometry that is a
function primarily of the observed sharpness. Applying these techniques to the
Cepheid target NGC 3627, we find that we are successfully able to photometer
the stars and clusters, as well as discriminating the cluster population with a
negligible number of false detections.
