85
```python
86
from PIL import Image, ImageEnhance
87

88
img = Image.open("photo.jpg")
89

90
# Enhance brightness
91
brightness = ImageEnhance.Brightness(img)
92
brighter = brightness.enhance(1.3)
93

94
# Enhance contrast  
95
contrast = ImageEnhance.Contrast(brighter)
96
contrasted = contrast.enhance(1.2)
97

98
# Enhance color saturation
99
color = ImageEnhance.Color(contrasted)
100
colorized = color.enhance(1.1)
101

102
# Enhance sharpness
103
sharpness = ImageEnhance.Sharpness(colorized)
104
sharpened = sharpness.enhance(1.2)
105

106
sharpened.save("enhanced.jpg")
