How To Compare Images

For a quantitative comparison between different signals or images, where the black and white levels are set to the same physical signal levels, please set the same

• Formula in the Formula bar
• Minimum and Maximum values in the Range toolbar
• Colour and inverse in the Colour toolbar

for both signals or images, as in the example inserted below.

Note that Intensity Bars in the two images have the same range -2 nA to 5 nA.
