from picamera import PiCamera, Color
from time import sleep

camera = PiCamera()

Set the camera to take a bit smaller photos (lower resolution). This will make our image processing a bit faster.



In [2]:

    
camera.resolution = (480, 320)
camera.vflip = True
camera.hflip = True



In [3]:

    
camera.start_preview()
camera.annotate_foreground = Color('white')
camera.annotate_text = "Colorswap Effect"
camera.annotate_text_size = 10
camera.image_effect = 'colorswap'
sleep(2)
camera.capture('img/colorswap.jpg')
camera.stop_preview()

One can see all the available effects by listing the camera EFFECTS

Let's just loop through some interesting ones:



In [5]:

    
camera.start_preview()
sleep(2)
cool_effects = ['none', 'watercolor', 'negative', 'emboss', 'washedout', 'solarize', 'oilpaint', 'sketch']
for effect in cool_effects:
    camera.image_effect = effect
    camera.annotate_text = "Effect: %s" % effect
    camera.capture('img/effect-%s.jpg' % effect)
    sleep(1)
camera.stop_preview()

Let's grab a few more photos to do some work on. Try to move in the frame as these are taken.



In [ ]:

    
camera.start_preview()
sleep(2)
camera.image_effect = 'none'
camera.annotate_text = ""
for i in range(3):
    camera.capture('img/frame-%s.jpg' % i)
    sleep(2)
camera.stop_preview()

Now we'll clean up our camera object...



In [6]:

    
camera.close()
