Example 1:

# Import Image from wand.image module 
from wand.image import Image 
  
# Read image using Image function 
with Image(filename ="koala.jpeg") as img: 
  
    # Sepia simulation using sepia_tone() function 
    img.sepia_tone(threshold = 0.6) 
    img.save(filename ="sepiakoala2.jpeg") 

Output:

Example 2: Increasing threshold value.

# Import Image from wand.image module 
from wand.image import Image 
  
# Read image using Image function 
with Image(filename ="koala.jpeg") as img: 
    # Sepia simulation using sepia_tone() function 
    img.sepia_tone(threshold = 1) 
    img.save(filename ="sepiakoala.jpeg")
