Need to enlarge to 900* 1200mm architectural photography, how accurate is the picture?

90cm× 120cm can be considered as A0 size.

Converted to 35.43×47.2 inches, temporarily regarded as 35×42 inches.

(35 * 300) * (42 * 300) = 65438+32 million pixels,

You need a digital camera that can output such a large pixel to meet the demand of 300dpi printing to 35×42 inches.

Reduce the requirements, if it is the normal printing resolution of 150 or the resolution of 175dpi. If it is 150, then you only need 66 million pixels to meet the requirements, and cameras with this pixel are still available.

If it is 175, then you need a 78-megapixel camera to meet each other's needs. This pixel camera is still available.

Don't fool people with the 135 camera (that is, Quan Huafu). No camera can satisfy this output at this stage.

If it is a medium format camera, brands such as Suha can output 65.438+0 billion pixels or 80 million pixels. However, if you have any equipment, you can do any work.

You'd better negotiate with others in case they don't accept your job then.
