Hi a1ex, your new cr2hdr works a treat now with actual exiftool are working! (saves me doing them 1 by 1 )

I have to say many thanks to you and the members who helped in developing the cr2hdr 

Cheers

During conversion, why the exiftool always say didn't work when I have them in every folder for conversion?

Do you have dcraw.exe on the same folder as well?

I just wanted to include my experience using Dual ISO somewhere for others that might be having the same struggle with the conversion to dng.

I am running Windows 8 64 bit which might be my problem .

I downloaded the cr2hdr zip folder from this post. I unzipped into the same folder as my dual ISO cr2 image file. I dragged the cr2 image onto cr2hdr and it launched, but it seemed to stop only part way through processing the file. It produced 2 files:

tmp.pgmCamera
tmp.txt

I searched for references to pgmcamera in an attempt to find a solution but found none, at first I thought I had the wrong copy of the .exe. In the end I had to run cr2hdr from the command prompt in order to produce a dng file I could use. After navigating to the correct folder just type:

cr2hdr.exe image.cr2

Where image.cr2 should be replaced with the name of the image you want to process.

Thanks but still have no joy with this, cr2hdr always show exiftool don't work... 

I just did one: exiftool -tagsfromfile img_1234.cr2 img_1234.dng

But I think cr2hdr already does this.

Hi engardeknaye,

Do you mind to PM me on how to copy exif tags from *.cr2 to *.dng with exiftool please?

Many thanks.
Robin

White balance has been completely erratic with dual ISO. I just tried copying all the exif tags from the .cr2 to the .dng with exiftool (presumably what cr2hdr already does) and the white balance was still off.

Not to suggest that it really matters.

I am using one of the cr2hdr_exp.exe and it always give different exposure results even though my images were exposed manually and in the same light setting.

Another issue is sometimes it has blue overcasts on shadow too.

Plus it doesn't always convert the dualiso raw file and sometimes it need few attempts before it detects the dualiso raw files.

A1ex, any chance for you to look into this.

Thanks
Robin

Hi,

When I do the conversion the exiftool always say didn't work for some reason 

Hi Alex, can you post the download link for this on your first page please?

Thanks
Robin

Uploaded a fix (download cr2hdr_exp.exe again). Can you check with your other pics?

Thanks for your help arrinkiiii and Danne...

Hi all, newbie here but I have done all the installations... on some test shots I've done, when viewing at 100% I can see some horizontal lines as opposed to normal exposed images. Is there any reason for this?

I tried cr2hdr.exe but seems that the converter does nothing just open and close in 1/2 secs... any thoughts?

Here is a sample, this is 100% crop, exposed to highlight to prevent pink/magenta at highlight area, dual ISO 100/1600...
