Does magnification reflect change in area or perimeter?

Postby wildfunguy » Sun Feb 03, 2013 10:14 pm

Suppose I have a 1x1 square with a height of 1 and an area of 1. Suppose I magnify it into a 2x2 square with a height of 2 and an area of 4. Would my magnification have been 2x or 4x?

I believe that if you find any picture that is 1éx, than the distance will be 10-times larger. Tha same for maps etc.

Cis or trans? That's what matters.

Thanks, but what is 1éx?


This link gave me the answer. Cambridgeincolour is a very good source for info about images and photography.

With that picture of the quarter, its perimeter is halved when you roll over:
1:2 or 0.5X magnification
, and its perimeter is one-fourth when you roll over:
1:4 or 0.25X magnification

It's perimeter (distance).
