The below example opens a jpg image and applies the grayscale operation on it.

# Importing Image and ImageOps module from PIL package  
from PIL import Image, ImageOps 
    
# creating a image1 object 
im1 = Image.open(r"C:\Users\sadow984\Desktop\download2.Jpg")
     
# applying autocontrast method 
im2 = ImageOps.grayscale(im1)
  
im2.show()
