Вот как я делаю снимок с помощью камеры
import logging
import gphoto2 as gp
def main():
def callback(level, domain, string, data=None):
print('Callback: level =', level, ', domain =', domain, ', string =', string)
if data:
print('Callback data:', data)
logging.basicConfig(
format='%(levelname)s: %(name)s: %(message)s', level=logging.WARNING)
callback_obj = gp.check_result(gp.use_python_logging())
camera = gp.Camera()
camera.init()
try:
camera_file_path = gp.check_result(camera.capture(gp.GP_CAPTURE_IMAGE))
except gp.GPhoto2Error as ex:
print("callback: ", ex, ex.code, ex.message, ex.string)
camera.exit()
if __name__ == "__main__" : exit(main())
Если камера не может сфокусироваться, она выдает следующую ошибку
...
WARNING: gphoto2: (ptp_usb_getresp [usb.c:466]) PTP_OC 0x90c8 receiving resp failed: Out of Focus (0xa002)
WARNING: gphoto2: (camera_nikon_capture [library.c:3153]) 'ret' failed: 'Out of Focus' (0xa002)

Код ошибки исключения -1
но как я могу получить Out of Focus
предупреждение?
