IS only helps with spacial motion, not temporal motion.

Does it indeed - and now here I am, thinking turning on IS freezes the world around me! Really, I was replying to alex when he said he uses dual_iso because he doesn't want to carry a tripod.

In a single capture, yes.  In a bracketing situation, IS doesn't suddenly develop skills which break the laws of physics  ;)

Which is exactly what I said above!   :P  :D

Now, let's cool down at the waterfall with a new dual ISO I took ;-)

Hi all.
I did a little test, showing how much we save the details in the image.

This is my first dual-iso image.  Driving home the other day, a really awesome thunderstorm was rolling in. I drove out into the field on the farm to get a wide, clean shot of the impending storm.  I used my 50 f1.8 on my Canon 6D and shot in dual iso 100/800.  It really helped me to get the bright clouds and the dark soil all in one shot.   The final image here is a pano stitched together in CS6.

Thanks for all the amazing work ML!

Danne,

The images with and without seem to be the exact same photo as  moving subjects seems to be the same.  With and without dual ISO would have to be two separate shots right ?   Cause you have to turn it on and off to take the two different shots yet moving objects seem to be in the same exact place.  Does this suggest that the differences can be HDR or post processing techniques ?

Thanks,
Scottie :o

Hi! It is the same pictures. The comparison reveals the higher dynamic range between the untouched lowest iso and the processed photo lifting back all those nice noisefree shadows. Of course it would be an even better comparison if I got a normal shot as well to put next to the dualiso-file

Thanks.
Sigma 35/1.4 art @ f/8.0, ML ISO 100/800.  20 images stitched in PS.  Some light processing with Viveza, to make the clouds a little more menacing.

The hardest part was brightness matching the exposures, due to the current DNG rendering method, that's based on the WL of the images.  There's probably an easier way, but I ended up just matching the exposures based on the histogram.

I've spoken to a1ex about it, fingers crossed it's somewhere near the top of his todo list.

Here is another one, looking opposite to the last, just before it bucketed down with rain.


Here is a single image from the above pano, before processing.

Where are those pictures from bkrzic?

It's in Croatia, Europe. Place called Mostari near Zagreb. I used 5D mk3 and Canon EF 24mm f1.4. Thank you all for great comments :)
