Fusion Timelapse Exposure

[reedpi]

Hey there!

How do you lock the exposure in the TL Video Mode on the Fusion?

I shot a sunset the other night and noticed that the exposure continued to automatically adjust throughout the video, which was no bueno as I wanted the colors to grow richer as the sun went down. 

I've searched for answers and scrolled through the menu settings and can't seem to find an exposure lock. 

Thanks in advance for your time,

JR

Be sure to turn on Protune first. After you do that, you should see the options to adjust the Exposure Value Compensation (EV Comp).

Jeff, 

I need to set the apature and leave it fixed for timelapse. 

I was not able to to control this with EVC. 

Can you manually control the apature / f-stop?

Protune is on. 

Please be specifc in your reply.

Thanks - John

There are several settings you can control once Protune is on. I believe you can set the ISO, exposure, and other similar settings on the Fusion. You can find out more in the Fusion manual at https://gopro.com/help/productmanuals.

GoPros don't control for aperture or f-stops, expect in terms of the EV comp and ISO, as mentioned earlier.

Same question here. Shot a time lapse of sunset last night and the exposure jumped around as it got darker. I set protune to on, ISO set and 0 exposure compensation and still fluctuation... Manual Settings are sparce on the Fusion. Any thoughts? I also have the YI 360 and do not have this issue, but there are more settings.

You might have been seeing a change in the ISO value as it got darker. On a sunset you should be fine locking it at 400. Also, setting the ev to -0.5 or lower will help with blow outs from the sun and should keep the overall exposure consistent.

Thanks for the feedback, danielr15.  I had the ISO set at 400 but every photo produced a different ISO value up to 400.  The selection in Timelapse Photo is labeled "ISO Max", so it seems that it is not able to be locked in.   I chose to set the EV at 0 as a test against my Yi 360VR, as the Yi has a tendancy to overexpose and I set that at -0.5 as a standard and get a nice result.
