“The photography business is different than Photography. The objective of a photography business is to use photography to rake in cash. The objective of Photography is to make beautiful photos. In that regard, if mini sessions, or mass production, can be quite lucrative if done well, then in a business sense it is actually quite creative. The business requirement is to provide a product that the customer will pay for.”
There is nothing wrong with assembly line photography because, as CC says, the business is about making money. We as photographers may balk that it’s not “pure photography” but if you can balance quality with the “take a number” formula, then why not?
