If you didn’t remove a larger sensor and cut it up and put it into your camera you don’t have a ‘cropped’ sensor. You have a sensor in APSC format, it is no more a ‘crop’ than a ‘full frame’ sensor is to medium format sensor. Short people aren’t ‘crops’ of taller people.

At any rate, a fast lens and a focal distance of at least 50 mm has brought me some good success. Pack a lot of patience and shoot a lot of frames. Bounce flash can save you indoors. If that isn’t possible, turn up the lights, more than you think you need.
