How to Measure Macro Magnification in Camera | Macro Photography

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.

Accurate macro magnification measurements
are done without any cropping or digital zooming.
You can crop all you want after you are done with measuring
but not before, because it will give you inaccurate results.
