Thanks a lot guys-
for the tips and for your time trying analyze my picture.

I will keep trying and update as soon as I can.
Cheers.

Thanks,

I know I must be doing something wrong.
Here is the original file:

I use CR2HDR latest versions in order to convert it to DNG (using BarracudaGUI).
Can you please help me and explain what is the best workflow for taking a picture using DUAL ISO? I'm very confused.
I understand that I should expose for the lower (base) ISO.
I thought I need to get all the highlights without clipping (that is why I used AETTR) and the recovery ISO (1600) will take care for the shadows - Am I wrong (apparently - yes..)?
So...
Should I expose for the highlights? shadows?
Should I avoid any clipping - shadows and highlights?

Sorry for the newbie questions,
10x again.

Anyone can help please to my previous post?

Hello Magic Lantern team,

I'm trying hard to get DUAL ISO to work, without much success.
I must do something wrong in the workflow or i do not understand how to use the feature, although i read a lot of material.

When trying to get most data out of the sensor, I'm shooting with AETTR and dual iso (100-1600).
That way I'm getting a lot of highlight information, but the blacks and shadows are pitch black.
When I try to recover the data, I must pull them all the way to +100 in order to see something in the shadows,
but that of course insert a lot of noise to it. So much i cant use the picture for almost anything.

Am I doing something wrong?
Does the DR is just too big that even DUAL ISO 100-1600 cant handle it?
Should i expouse the image without AETTR?
I'm using 70D,  latest CR2HDR, ACR 9.1.1 or LR 6 (same results).
I want to use it so much, help will be very appreciated.
Thanks.

Here is an example of DNG file (after CR2HDR) I cannot bring to life:

Hello,
I'm trying hard to get DUAL ISO to work, without much success. 
I'm using AETTR+DUAL ISO (usually 100-1600) to get the maximum data from the exposure.

When i take a picture of blue sky,clouds and trees/grass the exposure for the sky is perfect but everything else is pitch black in the dual iso CR2 file. When i drag the file into CR2HDR (latest version, from last build,dec 2015) the DNG file is exactly the same - no data in the blacks, and I need to drag the exposure a lot to the right in order to see some data. This adds a lot of noise.
I am using LR6 or ACR 9.1 - the results are the same. not good.
Maybe i dont know how to use this function, but i thought that after the DNG conversion the blacks/shadows will pop out automatically.
They do not pop out at all.

Any help will be welcomed, I'm very frustrated...

From my own research and from answers in this post,
I understand that 45 Mb/s card (such as sundisk extreme) will be enough for the 70D raw video.
m i right?
I have tried looking in other posts and I'm still not sure.
Some guys told that 95Mb/s is better, but its beyond camera capabilities so i don't understand how.

I'm really think that nikfreak and all others ML developers should get percentages from Sandisk selling of SD cards.
Thanks guys.

Hello guys and thanks a lot for your work. You made a lot of us happy  .
I want to prepare for RAW video and considering which card I need to buy in order to support 70D raw video at the max resolution and FPS that would be possible with ML.
Please help me choose between:
1. SDHC/SDXC?
2. 32GB? 64GB? MORE?
3  Needed writing speed for best results at max available quality and fps resolution?
4. SANDISK/LEXAR/OTHER?

Again - Thanks a lot guys for your work. Much appreciated.
