[Pinhole imaging] Doubts in photography experiment

Digital camera cmos? That is to say, only cmos is used, and there is no lens in front? The image in cmos is an inverted image, and then it is converted to the display screen through the circuit, which is a positive image. Because the digital camera is in normal use, the image after passing through the lens is inverted and the image on the screen is positive.

Film machine, the negative is the reverse image. The washing process is not clear. Come out and cut into 7 inches. You must be watching.
