What kind of camera do you need for advertising photography and photography?

According to customers' needs, any SLR can be used for general recipes. Architectural photography basically starts with a landline, and the high-end uses a landline+digital back. The beginning of car photography is digital back. Generally, low-end products are shot with a machine such as mamia ZD or 120 medium format film when large film is needed, and 450D can be used when large film is not needed. Anyway, except for relatively individual categories such as automobiles and buildings, all others are high-end = digital back, middle-end = medium-format film (it must be electronically divided rather than scanned later)/medium-format digital, and low-end = 135 digital SLR. There is advertising photography, a business income is almost a body of money, you can also choose the machine according to the customer's quotation.

As for camera shooting, I don't understand, and I guess it's similar. In addition, the equipment level in the later stage of camera shooting can directly determine the quotation.
