1. Mark DeLong works in commercials, celebrities and models. He makes pictures whether they look natural or trying to model for the camera. He works mostly in color and not in black and white too much. He typically has the models dress up, have makeup on and have their hair done. He says that his photos have a "distinct style".
2. He claims he likes working with variety of things but they all end up blending at the end because its his own type of work. All of his clients say he goes above and beyond and always meets their expectations or even go higher. He has the models and people getting their picture taken always have their hair and makeup down professionally done.
3. I think Mark works well with capturing the best angles and lighting. He doesn't just do a basic family photo, he can but he likes to look as if they models are the only thing in that photo. He wants them to stand out.
