Hi,

I was seeking a realistic workflow for my HDR "Magic Lanterns" timelapses, shooting in Bolivia. Via ML site, i came here. @davidmilligan you make a great plugin, necessary for photographers community.
The pictures of the day working great. But, when i work with HDR nights shoots (CR2), the render its working bad. And i dont know how to change the settings for this kind of timelapses. From darkness to light.

Has anyone pass trough the same situation? I really need help.

This is was my shoots:
issuebatch-01
issuebatch-02
issuebatch-03

And this is the output HDR:
hdr_output_wrong

Looks to me like you are simply way underexposed.

Okey David, but i was expecting the HDR leave the night black. I have noise image there, why? I can config the plugin for not touching those levels of darkness?

For example, here got from another shoot (Not HDR):

Thanks for all!

What’s the point of such an underexposed shot? I can barely see anything. There’s certainly no reason to use HDR processing methods if you are not exposing correctly to even capture the full dynamic range the camera is capable of in a single shot, usually around 9 or 10 EV. The images you’ve posted look to have barely 4 or 5 EV they are so underexposed.

The only reason of the underexposed is because the finish of the take is in daylight. I adjust the shoot for that scenario.

This its an example (now its public):

I'm new in all these stuff. But i made a few timelapses in HDR, from night to light, that i think i can have more than that render (the red noise one).

Here i got another with this noise>

You said that's imposible?
