if 36mm (3.6cm) give 1:1 , 60mm (6cm) should approximate to 1:2 or (36mm/60mm) = 0.6x magnificationOriginally posted by hwchoy
yah the ruler don't look so good, done without flash so maybe handshake.
how do you calculate magnification? Is it the length of the subject divided by 36mm? So I can see the ruler is 56mm does it mean mag = 0.64?
