Photography is poor for three generations. What does it mean that SLR destroys life?

This is just a metaphor, referring to the endless money spent playing SLR. There is a saying that photography is the art of running out of light. Without light, there would be no photography. Some movie friends interpret this sentence as "photography is the art of using light", that is to say, you have used up all the money in your pocket.

My aim is rational consumption, enough is enough. Buy equipment that suits you according to your financial resources, and don't follow suit.
