Auto Exposure?

[Jeff Lower]

I've been playing around doing some timelapse with my Scarlet and I thought I'd try using an auto exposure.

Then I started digging around on the forum, the web, and the manual, to see if I could figure out how to do it. I have come across a few hints at auto exposure with the epic/scarlet, but nothing solid. Perhaps I am not looking hard enough. Can someone please tell me how to do it?

Thanks in advance.

I'm pretty sure it can't be done with the current builds. I'm not even sure how it would work, would it adjust the aperture until just under traffic light clipping in any channel at the sensor?

There's no way to adjust gain of the sensor; that's the nature of Raw. So all that can be done is adjust aperture. As far as I can tell, lenses with an electronic aperture can be adjusted in 1/3 or 1/4 stops. So it won't be a smoooooooooooth transition over the range of the aperture over the course of the timelapse.

More common solution: use HDRx to get more stops available to you, and then grade it in post.

can't you hook up to a laptop with an electronic iris motor?
