Semiotics of photography is the observation of symbolism used within photography or "reading" the picture. This article refers to realistic, unedited photographs not those that have been manipulated in any way. Roland Barthes was one of the first people to study the semiotics of images. He developed a way to understand the meaning of images.

(In photography, the magnification is usually defined to be positive, despite the inverted image.) For example, with a magnification ratio of 1:2, we find f = 1.5 ⋅ F {\displaystyle f=1.5\cdot F} and thus the angle of view is reduced by 33% compared to focusing on a distant object with the same lens.

But seeing-in cannot really say in what way such surfaces resemble objects either, only specify where they perhaps first occur.
Linear or point-projection perspective (from Latin perspicere ' to see through ') is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection.
