How To Measure Macro Magnification – In Camera – Reverse Rings, Extension Tubes

There are two ways of measuring macro magnification – in Camera or in Photoshop.

A lot of people are familiar with the way to measure magnification in camera.

Many even believe that all you need to do is snap a photo of a ruler…

But they are missing the most important thing – magnification is directly related to the size of your camera sensor.

The point when you reach true 1:1 macro magnification, will vary depending on the camera you use.

In order to accurately measure your magnification – first you need to:

Know your sensor size !

The magnification you get will vary depending on the setup you use.

If you are using only one camera and only one lens – or the same reverse ring or extension tube with that lens – then your magnification will remain – the same… and you wouldn’t need to perform this check more than once…

But when you start combining your reverse rings & extension tubes with different cameras
or lenses with different focal length – the level of magnification changes.

The method of measuring magnification in camera is used when you need to know your exact magnification ahead of time
– before capturing the photo, so for all the new photos you are about to create.
