The HDR Timelapse mode combines the time-lapse with HDR (High Dynamic Range) mode. In other words, each frame of the time-lapse video will be an HDR photo.
This can be a complex goal to achieve, but the HDR Timelapse mode takes care of it very easily. This mode divides the screen into two parts. The upper part of the screen is about the time-lapse parameters. You can set the Interval value and the number of photos required for the time lapse video. The lower part of the screen shows the HDR settings The HDR part has three parameters to be adjusted, Center, EV(+-), and Frame.
Center: This parameter shows the exposure value that will sit in the middle of the sequence.
EV(+-): This parameter shows how many stops each change will be.
Frame: This parameter shows how many photos are to be taken for an HDR photo.
Interval: This parameter defines the duration between the HDR Photo sequences.
Frame:This parameter defines how many photos will be taken. You can set the frame number up to 65543. If you set the frame number to 0, this will mean that the time-lapse will continue until you stop it.
Preview: Goes to Timelapse gallery. You can view the photos taken in timelapse sessions.
Preset: You can save your settings by touching Preset button by entering a preset name.
Start: Start the mode.
Schedule: You can schedule your timelapse setup for a certain date&time using this screen.
