As ansius said - longer frame times would increase the motion blur and make it look smooth. 

The final post-processed video (I haven't done anything except CR2HDR and UFRAW, then used ffmpeg to timelapse). There's a very obvious jump where ML has turned off DualISO towards the end of the video.

Thanks for this Sepa, I've added this to my workflow. Kudos to you Sir.

Hi all,

General non-ML specific question - I have a flash mirror that mounts to my hotshoe on my 600D.

However, when you mount something in the hotshoe the camera assumes there is an external flash, and promptly disables the built in flash. Is there any way to disable this behaviour, so that I can fire the built in flash when there is something in the hotshoe?

Thanks for the info guys, much appreciated.

I will think before firing next time.

Added a new link. Not sure why the old one didn't work.

Should have the original CR2, interpreted DNG, UFRAW and resulting JPG.

Thanks for the help man.

Thanks for the help.

I changed the XML in the UFRAW file to look for a .DNG source file, rather than .CR2, and it interpreted fine - but it is now quite grainy....

Hi all,

I decided to experiment with the DualISO module to take a timelapse of a sunset - so I combined it with Auto-ETTR.

Normally my workflow is:

Import .CR2's
Rename
use UFRAW-BATCH to interpret Auto-ETTR
use FFMPEG to timelapse.


For the DualISO pictures when I use UFRAW-BATCH the pictures come out very grainy and very pink. I have attempted to use cr2hdr.exe to pre-process the DualISO before using UFRAW, but when I try and run UFRAW on the new dng files UFRAW can't find it as it is looking for the original .CR2.

Can anyone explain what my workflow should be in this situation?

Sorry I may have misunderstood - If I feed the dng's I get out of CR2HRD to UFRAW instead of the old CR2's, will that process the Dual ISO first with CR2 and the ETTR second with Ufraw?

(P.s. thanks for the speedy response - and the awesome feature-set!)

Edit: Seems I am supposed to do that - my google-fu seems to need some work. Thanks A1ex.

Edit2: Ufraw-batch is now looking for a CR2 - when obviously I have used CR2HRD to create a DNG. Obviously there isn't a converter to go back again - what's best here?

Hi all,

Ive been shooting some stuff in UFRAW mode with Dual ISO mode on.

UFRAW conveniently produces Jpegs, but doesn't sort out the Dual ISO mode, and CR2HDR.exe produces DNG files that can't be fed to UFRAW. Does anyone have a suitable workflow to sort them out?
