Here’s a litte Python script that enhance a jpg image.

import os
from PIL import ImageEnhance, Image

def enhance(input_dir, output_dir, factor=1.75):
    os.makedirs(output_dir, exist_ok=True)                                  # Create output directory   
    for filename in os.listdir(input_dir):                                  # Loop through all files
        if filename.lower().endswith('.jpg'):                               # Check if JPG image
            with Image.open(os.path.join(input_dir, filename)) as img:      # Open the image file
                enhanced_img = ImageEnhance.Color(img).enhance(factor)      # Enhance image
                enhanced_img.save(os.path.join(output_dir, filename))       # Save image

if __name__ == '__main__':
    input_directory = '.'                                                   # input directory
    output_directory = 'output'                                             # output directory
    enhance(input_directory, output_directory)                              # enhance
