Calculating Extension Required For Close-Up Photography
In order to calculate the total amount of bellows and monorail extensionneeded for close-up photography, use this formula: R x F + F = EX
R (reproduction ratio)
F (focal length in mm)
EX (extension in mm)
Let us say you want to photograph at life-size, or 1:1, using a 150mm lens.The amount of extension needed would be: 1 x 150 + 150 = 300mm
