The point is to show regular people wearing their pants. The deadpan poses, simple lighting, and rather boring (maybe even distracting) backgrounds reinforces the idea of the "everyman" that they're marketing to. Using studio lighting, backgrounds, professional models with more classical or exciting poses would undermine the brand's identity. The lack of perfection is intentional. Desirable even. The point of using 8x10 film over a cheaper digital medium is to show that even the average person should be fully respected, as they are. Digital is seen as too easy to Photoshop. Film is perceived to be more true to life. With digital, you can take 1,000 shots and pick the best one. With film, you are much more limited in your choices. It's a celebration of each of us, warts and all. It's a statement that these people are worthy of consideration through a costly medium just as they are. And if they be flawed, then that just makes them more relatable. They know their target audience won't be impressed by traditional fashion photography and all of it's tricks and glamour Dickies is consciously making a firm stance against that. At least that's my interpretation of it all. And I, for one, like it.
