Burst Mode and how to take Multiple Exposures #63

Open vitaminrad opened 6 years ago

vitaminrad commented 6 years ago

Howdy, I can connect to the camera and issue commands to set Burst Mode, however I cannot get multiple exposures using the take_photo() command. Am I missing something?

`from goprocam import GoProCamera from goprocam import constants gopro = GoProCamera.GoPro(constants.gpcontrol)

Waking up... Camera successfully connected! Connected to 10.5.5.9

gopro.mode(constants.Mode.MultiShotMode, constants.Mode.SubMode.MultiShot.Burst) gopro.gpControlSet(constants.Multishot.BURST_RATE, constants.Multishot.BurstRate.B3_1)

gopro.overview()

As you can see only one exposure is recorded... any ideas?

Oh hey,

gopro.take_photo()

switches to Photo mode, if you wish to capture a Burst sequence:

gopro.mode(constants.Mode.MultiShotMode, constants.Mode.SubMode.MultiShot.Burst)
gopro.shutter(constants.start)

However this will not give you different exposures (EV stops). For that check my script: https://github.com/KonradIT/gopro-py-api/blob/master/examples/hdrphoto.py

Thank you!

I discovered that the sequence of images is not readily available from listMedia(), however the files are still there.

The sequence for burst photos is as follows:

Gyyyxxxx.jpg

‘yyy’ = group number ‘xxxx’ = file number

If the number of burst photos taken is known, By getting the filename from listMedia, we can assume that incrementing the file number will link to valid media.
