Breathtaking. Only banding i really noticed was in the blue skies towards the beginning. Otherwise, I hope someday to get results half as good as you show here.

From a total noob. Intrigued by the concept of Dual ISO. Understand the concept. Installed the LR Plugin. Set my 70d to 100/1600 and took a completely nondescript photo.

Imported the cr2 into LR and with no adjustments, exported using the cr2HDR plugin.

Then exported the DNG to a 90% jpg, and again, no adjustments, here are the results:

The text file:

Active options:
--amaze-edge    : use a temporary demosaic step (AMaZE) followed by edge-directed interpolation (default)
--cs2x2         : apply 2x2 chroma smoothing in noisy and aliased areas (default)
--no-bad-pix    : disable bad pixel fixing (try it if you shoot stars)
--wb=graymax    : set AsShotNeutral by maximizing the number of gray pixels (default)

I don't even know what I am doing, and this is incredible!

Now, why do I want to pair this with ETTR?

Thanks,

Brand new. Interested in Time Lapse.  Here is my first attempt, and I just want to know if the problem is related to ML, or the lens, or the camera or something else entirely.

Canon 70D, Tamron 24-70, manual focus, stabilization off. Tripod mounted, most all settings set to manual. ML intervalometer set to 3 sec.

In alternate frames, the camera seems to jump up and down, just a little. Every other frame, all odd numbered frames seem to be recorded at a few pixels higher than the even numbered frames. The camera is mounted to tripod, and very steady.  Seems like some sort of software adjustment happening with the capture? The video goes very quickly, so it is hard to see.  I made a PDF with 10 sequential frames, but I don't know how to share a PDF file.

Here is a second export using only the odd numbered frames. Steady as a rock.  Weird.

Anyway, I don't think it is ML, but thought I would ask here first.

Thank you, love this software!
