The proportion we say here refers to the proportional relationship between the size of the negative image and the real thing. The maximum shooting ratio of the standard lens of 35mm camera is1:10. As a matter of fact, it is internationally recognized in the photography field that the images with the ratio of1:1:4 belong to macro photography, while those with the ratio of10:1~ 200:1belong to macro photography.
