dear all

would you tell me how can I use the simulated long exposure during photo taking?
is the auxiliary light turned on only in the air?

thank you very much

I bet its only on for landing and taking off

I know lots about a long exposure, but what's a simulated long exposure?

page 103 of the manual

do you mean the auxiliary light ?

That aux light can be set between Auto, On, and Off. Default is Auto.

It's a way to "fake" very long exposure photography by taking several shorter exposures and stacking them.
This used to be done in a computer, but DJI do it in-camera.

Hi there. Thank you for reaching out. To shoot regular photography in dark scenarios, the footage brightness can be increased by increasing ISO or extending exposure time. However, a relatively high ISO is accompanied by more noise, and a relatively long exposure time accumulates jitter to the aircraft and gimbal, both resulting in blurred footage. Simulated long exposure involves dividing a long target exposure time period into a number of short exposure time periods in order to obtain multi-frame footage. After the motion estimation, alignment, and stacking of the obtained footage, the output will be footage with a total exposure time equal to the preset long exposure time. The above motion estimation and alignment help to avoid accumulating jitter to the aircraft and gimbal. Furthermore, Yes. The auxiliary light located at the bottom of the aircraft can be turned on or off using the Fn button (customizable button) on DJI RC-N2 or the customizable C1/C2 button on DJI RC 2 or you can enter the camera view in the DJI Fly app, go to Settings, Safety, and Auxiliary LED. Then select “On”.

Auxiliary LED settings: The auxiliary light can be set in the app to Auto, On, or Off. In Auto, the auxiliary light is automatically enabled when there is insufficient ambient light.

Dear Paladin

Your explanation is appreciated.

I want to know whether the mini 4 pro has some function or feature to implement the Simulated long exposure. Or something else.

What is the meaning of specifying the Simulated long exposure in the manual?

Dear Paladin

Your explanation is appreciated.

The last two replies answered your question already.

Does the auxiliary light drain the battery faster ?

Thank you for your response. This part of the power consumption was ignored which means it will not make the battery drain much faster. Hope this helps. Have a nice day ahead.

Thanks for the reply. However, it confirms some kind of 'extra' drain. Which can be useful information when sparing the charge. Other factors for additional battery drain are : high speed, strong wind, cold, use of video and even the obstacle avoidance. (correct me if I'm wrong ;-) )
Kind regards.

Thank you for your response. I understand. You may consider it as less to no effect as this part of the power consumption was ignored. If you have other inquiries, feel free to contact us. Have a nice day!
