One simple way is:
```
from PIL import Image
import numpy as np
# Open image
img = Image.open('path_to_image.jpg')
# convert image to numpy array
img_arr = np.array(img)
```
Where img_arr will now be an array with dimensions/ shape (height, width, RGB)
Then you can manipulate the array/ image like any other numpy array and then turn it back into a PIL image using
```
pil_img = Image.fromarray(img_arr)
```
