Python PIL | ImageChops.subtract() and ImageChops.subtract_modulo() method
PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities.
ImageChops.subtract() method –
This method subtracts two images, dividing the result by scale and adding the offset. If omitted, scale defaults to 1.0, and offset to 0.0.

Syntax: ImageChops.subtract(image1, image2, scale = 1.0, offset = 0)
Parameters:
image1: first image
image2: second image
scale: it is floating point value (if the value keeps on increasing, resultant image becomes darker and darker)
offset: numeric value (if value keeps on increasing, resultant image becomes lighter)Return Value: An Image

ImageChops.subtract_modulo() method –
This method is also used to subtract two images but without clipping the result.
Syntax: ImageChops.subtract_modulo(image1, image2)
Parameters: This method takes two images as parameters.
Return Value: An Image.
