There is a very practical answer to this question.
five words: four hundred dollars an hour
But for a more philosophical one, it is very simply a question of what you are trying to photograph. Some of the ugliest people I have ever photographed have been size two models. Vapid, narcissistic, self-aggrandizing, bundles of unpleasantness wrapped up in a body that is a 10. It is very hard to shoot someone in a way that you can’t see the rotting cesspool that is their soul. I’d rather shoot an overweight person with a good attitude and a modicum of humility about themselves. Real photographers capture more than the body, we get the distinct honor of capturing a glimpse into the soul. If you can’t see past that, it is a sad loss indeed.
But, I don’t expect you to change your mind today, in fact I wish you luck that you might find a gorgeous person to be with you who is shallow enough not to be detoured by your view on life. I even wish you eternal youth and boundless wealth, so that your world view never need be shattered by the reality that you will one day shrivel up and die, ugly and alone.
And for the record, so you don’t need to make assumptions on my appearance, YES, I am getting old (I’ve been a professional photographer for over 20 years) and YES, I’m not in as good a shape as I used to be (about 30 lbs overweight). But here is the funny thing, I have the personal cell numbers of over a thousand actresses, actors, models, and musicians who I have shot over the years, and when I text or call one of them, they not only remember who i am, but they are excited to hear from me, and it might just be because I am far more interested in who they are than what they look like. So, all in all, it seems like living life by my ideals has also netted me the benefits you hope to achieve by clinging to yours.
