Friend, thank you so much, now i 100% understand of the function already. 

After shoot the CR2 with dual ISO, then use cr2hdr.exe make the DNG file, it can open in photoshop like RAW file, it will less noise and it can adjust recovery/shadow until a perfect HDR photo, awesome !!!


Nice works, thanks again 

What's the matter with cr2hdr?

Maybe i misunderstanding of the Dual ISO function, i think it is direct adjust and shoot will get effect view in camera.
But i shoot every Dual ISO photo will get whole line texture picture like the photo i share.

Now i understand the Dual ISO function photo after shoot the CR2 file then need using computer cr2hdr.exe convert to DNG file only get the perfect Dual ISO image.

Also, please don't create duplicate posts in the forum.

ok, thanks and sorry for the duplicate posts.

For this DualISO shooting, it is only the way using the CR2 file convert to DNG file using "cr2hdr.exe"? No other way, right?

Hi friend, i read it  already, i saw that "3 ADTG/CMOS register tweaking", but it showing explain some code, i can't understand, i'm still confuse of it.

And i read many page of this topic too, i found some people is after shooting Dual ISO as CR2 photo, then drag the file to "cr2hdr.exe" then will be convert to DNG file with dual ISO combie.

Dual ISO is only success with this cr2hdr.exe software or got any solution can direct perfect shoot in the camera?

Hope someone can let me know the clearly answer, thanks
